Major League Baseball recognizes the player or players in each league{{ref label|League|a|a}} with the most wins each season.{{ref label|Qualify|b|b}} In baseball, wins are a statistic used to evaluate pitchers. Credit for a win is given by the official scorer to the pitcher whose team takes and maintains the lead while he is the pitcher of record. If a game is tied or if the lead changes to the other team, all pitchers who have participated and exited the game to that point are unable to receive credit for the victory. A starting pitcher is ineligible for the win unless he pitches at least five innings. (If he doesn't, but nevertheless leaves his team with a lead that it never relinquishes (a rather uncommon combination),{{Cite web |title=Relief Win (RW) |url=https://www.mlb.com/glossary/standard-stats/relief-win |access-date=July 24, 2024 |website=MLB.com}} the scorer would award the victory to the relief pitcher who was "most effective... in the official scorer's judgment".){{cite web|url=http://mlb.mlb.com/mlb/downloads/y2008/official_rules/10_the_official_scorer.pdf|title=The Official Scorer: Winning and Losing Pitcher|publisher=Major League Baseball|access-date=March 25, 2010|archive-date=February 5, 2009|archive-url=https://web.archive.org/web/20090205082219/http://mlb.mlb.com/mlb/downloads/y2008/official_rules/10_the_official_scorer.pdf|url-status=live}}

History

The National League's first win champion was Albert Spalding, who led the senior circuit with 47 wins after leading the semi-professional National Association in each of its five seasons. Hall of Fame pitcher Cy Young led the American League in wins in each of its first three years (1901–1903), amassing 33, 32, and 28 victories in those seasons for the Boston Americans.{{cite web|url=https://www.baseball-reference.com/players/y/youngcy01.shtml|title=Cy Young Statistics and History|work=Baseball-Reference.com|access-date=March 26, 2010|archive-date=February 10, 2009|archive-url=https://web.archive.org/web/20090210031934/http://www.baseball-reference.com/y/youngcy01.shtml|url-status=live}} Warren Spahn leads all players with 8 win championships for the Boston and Milwaukee Braves in his 21 seasons.{{cite web|url=https://www.baseball-reference.com/players/s/spahnwa01.shtml|title=Warren Spahn Statistics and History|work=Baseball-Reference.com|access-date=March 26, 2010|archive-date=April 25, 2021|archive-url=https://web.archive.org/web/20210425191534/https://www.baseball-reference.com/players/s/spahnwa01.shtml|url-status=live}}

=Most wins in a Major League season=

File:Radbourne charles 1.jpg

Charles "Old Hoss" Radbourn holds the single-season record for the most games won in a major league season; he notched 59 victories in 1884.{{cite web|url=https://www.baseball-reference.com/leaders/W_season.shtml|title=Single-Season Leaders & Records for Wins|work=Baseball-Reference.com|access-date=March 26, 2010|archive-date=January 2, 2021|archive-url=https://web.archive.org/web/20210102185550/https://www.baseball-reference.com/leaders/W_season.shtml|url-status=live}} There is a discrepancy in Radbourn's victory total in 1884. The classic MacMillan Baseball Encyclopedia, as well as other sources credit Radbourn with 60 wins (against 12 losses), other sources place his win total as high as 62. He and John Clarkson (53 wins in 1885) are the only pitchers to exceed 50 wins in a single season in the current major leagues; Guy Hecker also accomplished the feat in the American Association. The American League leader is Jack Chesbro, who won 41 games for the New York Highlanders in 1904; his total is the highest since 1901.{{cite web|url=https://www.baseball-reference.com/players/c/chesbja01.shtml|title=Jack Chesbro Statistics and History|work=Baseball-Reference.com|access-date=March 26, 2010|archive-date=May 27, 2009|archive-url=https://web.archive.org/web/20090527130837/http://www.baseball-reference.com/players/c/chesbja01.shtml|url-status=live}} The highest total in the National League since 1901 is Mathewson's 37 victories in 1908.

The number of wins required to lead the league each season has gone down significantly over the last century. For example, from 1900 to 1920, the average number of wins for the AL league leader was 30.8; from 1990 to 2010, it was 20.9.

=Ties=

Ties for the win championship are common. The most recent tie in the American League was in 2012, when Jered Weaver and David Price tied for the lead with 20 wins each, and the most recent tie in the National League was in 2011, when Ian Kennedy and Clayton Kershaw tied with 21 wins each. The most pitchers to share the title in a single season is six, accomplished in 2006 when Aaron Harang, Derek Lowe, Brad Penny, John Smoltz, Brandon Webb, and Carlos Zambrano each won 16 games in the National League. In the American League, four pitchers shared the award in the strike-shortened 1981 season.
