'''Seals Stadium''' was a [[Minor League Baseball]] stadium in [[San Francisco]], California, United States; it later became the first home of the [[Major League Baseball|major-league]] [[San Francisco Giants]]. Opened in the [[Mission District, San Francisco|Mission District]] in 1931, Seals Stadium was the longtime home of the [[San Francisco Seals (baseball)|San Francisco Seals]] (1931–1957) of the [[Pacific Coast League]]. The PCL's [[Mission Reds]] (1931–1937) shared the ballpark with the Seals for the first seven years, then moved to [[Los Angeles]] and became the [[Hollywood Stars]].

In 1958, Seals Stadium became a temporary home for the Giants for their first two seasons in San Francisco while [[Candlestick Park]] was under construction. Less than three decades old, Seals Stadium was demolished in late 1959 after construction on [[Candlestick Park]] was finished.<ref name=tutbe>{{cite web|url=http://mlb.mlb.com/news/article.jsp?ymd=20060420&content_id=1410202|publisher=Major League Baseball |title=There used to be a ballpark here|last=Sullivan|first=T.R.|date=April 21, 2006|archive-url=https://web.archive.org/web/20131203013205/http://mlb.mlb.com/news/article.jsp?ymd=20060420&content_id=1410202| archive-date=2013-12-03 |access-date=December 1, 2013}}</ref>

==History==
===Early years===
Seals Stadium opened on April 7, 1931, after a construction cost of $1.25{{nbsp}}million. It was of concrete and steel construction and was named after its key tenant, the [[Pacific Coast League]]'s [[San Francisco Seals (baseball)|San Francisco Seals]]. It was uniquely designed to host another San Francisco Pacific Coast League team, the [[Mission Reds]]. The ballpark land had been part of pioneer land plots of the "Home Plate Mine", which became an early nickname of the ballpark. Built during the [[Great Depression]], Seals President [[Charles H. Strub|"Doc" Strub]] described how laborers would leap onto the running boards of his automobile and beg for the opportunity to work on the project for $3 a day.<ref>{{cite web |url=http://www.foundsf.org/index.php?title=1931-WWII:_The_Seals |title = 1931-WWII: The Seals - FoundSF}}</ref><ref name="baseball-almanac.com">{{cite web|url=http://www.baseball-almanac.com/stadium/st_seals.shtml|title=Seals Stadium Historical Analysis by Baseball Almanac|website=[[Baseball Almanac]]}}</ref>

With two tenants, Seals Stadium was uniquely constructed with three dressing rooms. One dressing room was for the visiting team, and one for each of the minor league home teams. The stadium had six tower banks for lighting, which were described as the best in minor league baseball at the time.

Opening with a capacity of 18,600, Seals Stadium had no roof over the grandstands, because of San Francisco's little rainfall during the summertime and the fans' preference to sit in the sun.<ref>The Sporting News "Take Me Out To The Ball Park", 2nd Edition, 1987 by Lowell Reidenbaugh – p 230</ref> The original uncovered grandstand stretched from foul pole to foul pole. In some years during its minor league days, a live seal was kept in a water tank underneath the grandstand. The field was oriented southeast (home plate to second base), with the right field bleachers bounded by 16th Street.<ref name=sshpfa>{{cite news|url=https://www.wired.com/playbook/2010/02/seals-stadium-home-plate-found-after-50-years/|magazine=Wired|last=Malinowski |first=Erik |title=Seals Stadium home plate found after 50 years |date=February 12, 2010 |access-date=December 1, 2013}}</ref>

The initial dimensions of the outfield were planned to be {{convert|364|ft|m|abbr=on}} along the left field foul line, {{convert|450|ft|m|abbr=on}} to center field, and {{convert|385|ft|m|abbr=on}} to the right field foul line.<ref>San Francisco ''Examiner'', February 1, 1931, p.29</ref> The eventual posted distance to left field was {{convert|365|ft|m|abbr=on}}.

For the 1946 season, bleachers were built across the right field area, with the plan to reduce the foul line distance by "about 25 feet".<ref>San Francisco ''Examiner'', January 21, 1946, p.17</ref> The final distance turned out to be posted as {{convert|348|ft|m|abbr=on}}. An inner fence was also constructed across center field, reducing the distance to about {{convert|400|ft|m|abbr=on}}.

For the 1951 season, bleachers were built in front of the left field wall, reducing the foul line distance to {{convert|347|ft|m|abbr=on}}. This was done at the behest of the Seals' president, Paul Fagan, and the area was dubbed "Paul's Porch". That experiment lasted just the one season, and it was removed in the spring of 1952.<ref>San Francisco ''Examiner'', January 31, 1952, p.26</ref>

=== San Francisco Seals (1931–1957) / Mission Reds (1931–1937) ===
The San Francisco Seals began play in 1903 as charter team in the [[Pacific Coast League]]. They played at the wooden [[Recreation Park (San Francisco)|Recreation Park]], located at Valencia and 14th Street, before Seals Stadium was built for them. In 1926, the Pacific Coast League Mission Reds (named after the [[Mission District]]) relocated from [[Los Angeles]] where they had been called the [[Vernon Tigers]]. They joined the Seals at Recreation Park.<ref name="sfchronicle.com">{{cite web|url=https://www.sfchronicle.com/bayarea/article/In-the-depths-of-the-Depression-SF-had-the-best-12908333.php|title=In the depths of the Depression, SF had the best ballpark in the country - SFChronicle.com|date=12 May 2018|website=[[San Francisco Chronicle]]}}</ref>

[[File:San Francisco Seals in Japan 1949.jpg|thumb|left|1949 San Francisco Seals in Japan]]

On March 13, 1931, Seals Stadium officially opened with a spring training game between the Seals and the [[Detroit Tigers]].<ref name="foundsf.org">{{cite web|url=http://www.foundsf.org/index.php?title=1931-WWII:_The_Seals|title=1931-WWII: The Seals – FoundSF|publisher = Shaping San Francisco}}</ref> At the regular season home opener on April 7, 1931, [[Ty Cobb]] threw out the first pitch, with 25,000 fans in attendance.<ref name="goodoldsandlotdays.com"/> The Missions opened their home season at Seals Stadium a week later, April 14 - hosting the Seals.

Notably, [[National Baseball Hall of Fame and Museum|Hall of Famer]] [[Joe DiMaggio]] grew up in San Francisco and played for the Seals from October 1932 through 1935. In 1933, DiMaggio hit safely in a record 61 straight games for the Seals, with 169 RBI and a batting average of .340.<ref name="foundsf.org"/> Another future major league player [[Gus Suhr]] had an incredible season for the Seals in 1929, hitting .381 with 51 home runs and 177 RBI. Other notable Seals players included Hall of Famers [[Earl Averill]], [[Paul Waner]], [[Lloyd Waner]], [[Joe Cronin]] and [[Lefty Gomez]], as well as [[Dominic DiMaggio]], [[Vince DiMaggio]], [[Albie Pearson]] and [[Ferris Fain]].{{cn|date=June 2022}}

[[File:Corbett & Fields, 1933.jpg|thumb|[[Young Corbett III]] (facing camera) and [[Jackie Fields]] at the Seals Stadium, 1933]]
Seals Stadium hosted other events. On February 22, 1933, boxer [[Young Corbett III]] defeated [[Jackie Fields]] at the stadium, earning the title of [[List of welterweight boxing champions|World Welterweight Champion]]. Corbett later won the [[List of middleweight boxing champions|Middleweight Championship]] at Seals, beating [[Fred Apostoli]] on February 22, 1938.

While the Seals remained, the [[Mission Reds]] left Seals Stadium and moved to [[Los Angeles]] in 1938, where they became the [[Hollywood Stars]], playing at [[Gilmore Field]].{{cn|date=June 2022}} The Missions wrapped up their time at Seals Stadium with a doubleheader win over San Diego on September 19, 1937.

After World War II concluded, Seals owner Paul Fagan invested in a stadium makeover. Fagan had all billboards removed and had the entire stadium painted green. Nearby the stadium was the Rainier (later Hamm's) Brewery. The roof of the brewery contained a sign depicting an enormous foaming glass of beer that was lit up at night and was visible from inside the park. Also nearby was the Langendorf Bakery, which sent the smell of baking bread into the ballpark. At the corner of 16th Street and Bryant was the Double Play bar and grill, which was open from 1909 until a fire destroyed it in 2022.<ref>{{cite web|url=https://www.sfchronicle.com/bayarea/article/A-total-loss-Fire-destroys-S-F-Mission-17465003.php|title=‘A total loss’: Fire destroys S.F.

The Seals drew well at Seals Park. In 1948 they set a minor league attendance record, drawing 670,000 fans. This showcased the feasibility that San Francisco could someday sustain and support a Major League franchise and Fagan was posturing to position the Seals to become a major league franchise.<ref>{{cite web|url=http://www.hawkeegn.com/Seals/|title=San Francisco Seals|website= hawkeegn.com}}</ref><ref name="sfchronicle.com"/>
In 1950, Fagan briefly halted peanut sales at the stadium, possibly due to cleanup costs. The move was ill-advised, as disgruntled fans brought their own peanuts and hurled the shells onto the field. After the “Peanut Revolt,” Fagan gave away 18,000 free bags of peanuts.<ref name="sfchronicle.com"/>

The Seals closed out their time in San Francisco on a high note, winning the PCL championship. The actual final PCL games at Seals Stadium were a meaningless doubleheader loss to the [[Sacramento Solons]] on September 15, 1957. The second game was played for laughs, with managers and even the umpire taking brief turns at playing for the teams. The finale was well-attended, with 15,484 spectators. With the Los Angeles and San Francisco markets due to be taken over by major league baseball in 1958, it was feared that the PCL would disband.<ref>San Francisco ''Chronicle'', September 16, 1957, p.25</ref> But the PCL continued, in other cities.

In 1958, after the [[New York Giants (NL)|New York Giants]] confirmed their intention to move to San Francisco, the Seals relocated to [[Phoenix, Arizona]], becoming the [[Phoenix Giants]].

===San Francisco Giants (1958–1959)===

On May 28, 1957, the [[New York Giants (NL)|New York Giants]] and owner [[Horace Stoneham]] announced they intended to leave the [[Polo Grounds]] in [[New York City]] and relocate to San Francisco. The major league owners approved the move under the condition that the [[Brooklyn Dodgers]] would also complete their intended move to Los Angeles. Dodgers' owner [[Walter O'Malley]] and San Francisco Mayor [[George Christopher (mayor)|George Christopher]] had worked to partner with Stoneham on the move to San Francisco. Both teams moving to California together made sense for scheduling balance and travel. On August 19, 1957, official announcement of the moves was made.<ref name="sanfrancisco.giants.mlb.com">{{cite web|url=http://sanfrancisco.giants.mlb.com/sf/history/timeline.jsp|archive-url=https://web.archive.org/web/20100613150141/http://sanfrancisco.giants.mlb.com/sf/history/timeline.jsp|url-status=dead|archive-date=June 13, 2010|title=Giants Timeline|website=San Francisco Giants}}</ref><ref name="auto">{{cite web|url=https://www.history.com/this-day-in-history/baseball-owners-allow-dodgers-and-giants-to-move|title=Baseball owners allow Dodgers and Giants to move|website=HISTORY}}</ref> By agreement, both teams would play in temporary locations while each city build a new ballpark. The Giants agreed to play at Seals Stadium while [[Candlestick Park]] was under construction and the Dodgers played at [[Los Angeles Memorial Coliseum]], (bypassing smaller [[Wrigley Field (Los Angeles)|Los Angeles Wrigley Field]]), while [[Dodger Stadium]] was under construction.<ref name="sanfrancisco.giants.mlb.com"/><ref name="auto"/>

To accommodate [[Major League Baseball]], more seating was needed at Seals Stadium. A separate uncovered bleacher section was added in left field. This reduced the left field line to {{convert|361|ft|m|abbr=on}}, with left-center posted as {{convert|364|ft|m|abbr=on}}. The other posted distances were {{convert|401|ft|m|abbr=on}} and {{convert|397|ft|m|abbr=on}} to the center field corners; {{convert|350|ft|m|abbr=on}} to right center field; and {{convert|348|ft|m|abbr=on}} along the right field line. The ballfield remained without a warning track. Given the temporary usage by the Giants, Seals Stadium was not renamed.<ref name=Lowry>{{cite book |title=Green Cathedrals |last=Lowry |first=Philip |year=2006 |publisher=Walker & Company |isbn=978-0-8027-1608-8 |page=212 |url=https://books.google.com/books?id=Afo5vtVTz4wC&q=green%20cathedrals&pg=PP1 }}</ref> The original plan was to play just the first year at Seals Stadium, but that proved to not be the case.<ref name=sfpsimj/>

[[File:Willie Mays cropped.jpg|thumb|left|Willie Mays with the SF Giants in 1961]]

On April 15, 1958, the first [[West Coast of the United States|West Coast]] Major League game was played at Seals Park. With Hall of Famers [[Willie Mays]] and [[Orlando Cepeda]], the Giants opened with an 8–0 victory over [[Don Drysdale]] and the new [[Los Angeles Dodgers]]. Mays would go on to hit .347 with 29 home runs in 1958 and Cepeda would win the [[National League Rookie of the Year]] Award. [[Willie McCovey]], another future Hall of Famer, then won the award in 1959.<ref name="sanfrancisco.giants.mlb.com"/><ref>{{cite web|url=https://www.baseball-reference.com/awards/roy_rol.shtml|title=MLB Rookie of the Year Awards, Mariano Rivera, Trevor Hoffman, & Rolaids Relief Award Winners|website=Baseball-Reference.com}}</ref>  Cepeda would hit his first career home run at Seals Stadium on April 15, 1958.<ref name="baseball-almanac.com"/>

The Giants drew well at Seals Stadium. Finishing 80–74 in 1958, they drew 1,272,625 fans. That increased to 1,422,130 in 1959, when the Giants finished 83–71.<ref>{{cite web|url=https://www.baseball-reference.com/teams/SFG/1958.shtml|title=1958 San Francisco Giants Statistics|website=Baseball-Reference.com}}</ref><ref>{{cite web|url=https://www.baseball-reference.com/teams/SFG/1959.shtml|title=1959 San Francisco Giants Statistics|website=Baseball-Reference.com}}</ref>

Prevailing winds to left field aided right-handed hitters; of the 45 home runs hit in its first 19 major league games in 1958, 36 were to left field.<ref name=ffhrh>{{cite news|url=https://news.google.com/newspapers?id=ps4TAAAAIBAJ&pg=7178,1600863|newspaper=Eugene Register-Guard|agency=Associated Press |title=45 home runs hit at Seals Stadium |date=May 9, 1958|page=4B }}</ref> All-Star Giants pitcher [[Johnny Antonelli]] was not a fan of the ballpark, telling reporters after a loss, "A pitcher should be paid double for working here.

At the time, its weather was thought to be considerably less favorable than the site of the park under construction at [[Candlestick Point]].<ref name=sfpsimj/>

The final game at Seals Stadium took place on September 20, 1959. The Giants lost to the Los Angeles Dodgers 8–2 in front of 22,923 spectators.<ref>{{cite web|url=https://www.baseball-reference.com/boxes/SFN/SFN195909200.shtml|title=Los Angeles Dodgers at San Francisco Giants Box Score, September 20, 1959|website=Baseball-Reference.com}}</ref>

===1959 demolition and site usage===

With Candlestick Park nearing completion, Seals Stadium was demolished in November 1959. Many of the seats and the light towers were eventually repurposed at [[Cheney Stadium]] in [[Tacoma, Washington]].<ref name=tutbe/><ref name=cstfpt>{{cite news|url=http://seattletimes.com/html/sports/2001990554_rainiers28.html|newspaper=Seattle Times |title=Cheney Stadium the focal point for Tacoma's link to M's |last=Sherwin |first=Bob |date=July 28, 2004 |access-date=December 1, 2013}}</ref>

After demolition, the site (bounded by Bryant Street, 16th Street, Potrero Avenue and Alameda Street) initially housed a [[White Front]] department store. For many years after, there were several automobile dealerships after the 1982 demise of Van Ness Avenue's famed [[auto row]]. In the late 1990s, the area was converted to a shopping center.<ref name=tutbe/><ref name=srwgod>{{cite news|url=https://www.nytimes.com/2012/10/25/sports/baseball/big-box-stores-where-giants-seals-stadium-once-stood.html?_r=0|newspaper=New York Times|last=Branch|first=John|title=Shoppers roam where Giants once did|date=October 24, 2012|archive-url=https://web.archive.org/web/20200711023250/https://www.nytimes.com/2012/10/25/sports/baseball/big-box-stores-where-giants-seals-stadium-once-stood.html?_r=0|archive-date=2020-07-11|url-access=subscription|url-status=live|access-date=December 1, 2013}}</ref>

==2008: 50th anniversary tribute==
On April 15, 2008, the San Francisco Giants paid tribute to the 50th anniversary of their move to Seals Stadium. There was a ceremony at the Seals Stadium site and another at [[Oracle Park|AT&T Park]] to commemorate the 50th anniversary of the 1958 Opening Day.  The Giants' home game that day – against the [[Arizona Diamondbacks]] – was started at 1:35&nbsp;p.m., the starting time commemorated the same time of day Giants' pitcher [[Rubén Gómez (baseball)|Ruben Gomez]] threw the first pitch at Seals Stadium on Opening Day, April 15, 1958. The first 20,000 fans attending the Diamondbacks-Giants game received a commemorative poster print of the Gomez' first pitch from 1958. [[Orlando Cepeda]] and [[Gino Cimoli]], the first men to bat on that historic day, threw out the ceremonial first pitch.<ref name="ReferenceB">{{cite web| url = http://sanfrancisco.giants.mlb.com/news/press_releases/press_release.jsp?ymd=20080411&content_id=2516478&vkey=pr_sf&fext=.jsp&c_id=sf| url-status = dead| archive-url = https://web.archive.org/web/20080413155955/http://sanfrancisco.giants.mlb.com/news/press_releases/press_release.jsp?ymd=20080411&content_id=2516478&vkey=pr_sf&fext=.jsp&c_id=sf| archive-date = 2008-04-13| title = The Official Site of The San Francisco Giants: Official Info: Giants to commemorate first game at Seals Stadium}}</ref><ref name="sandiegouniontribune.com">{{cite news |url=https://www.sandiegouniontribune.com/sdut-giants-celebrate-50th-anniversary-1st-game-san-fra-2008apr15-story.html|title=Giants celebrate 50th anniversary|work=[[San Diego Union-Tribune]]|date=2008-04-15| archive-url=https://web.archive.org/web/20190422173804/https://www.sandiegouniontribune.com/sdut-giants-celebrate-50th-anniversary-1st-game-san-fra-2008apr15-story.html  |archive-date=2019-04-22 |url-status=live}}</ref>

There were pre-game events at the site of Seals Stadium. Ceremonies included the unveiling of a new bronze historical plaque at the site, a recreation of the radio call of the first pitch by [[Jon Miller]], an honoring of Mike Murphy, the Giants 50-year legendary clubhouse manager, as well as speeches/recollections by [[Willie Mays]] and others. Among those recognized were Giants Hall of Famers Mays and [[Orlando Cepeda]] and 1958 Giants players [[Jim Davenport]] and [[Eddie Bressoud]].  Descendants of former Giants' owner [[Horace Stoneham]] and Mayor [[George Christopher (mayor)|George Christopher]] (both instrumental in moving the Giants from New York to San Francisco) were in attendance.<ref name="ReferenceB"/><ref name="sandiegouniontribune.com"/>
