Jerry Koosman was on the mound for the final out of the 1969 World Series, having won both of his starts to help the New York Mets to their improbable championship. He was an excellent pitcher in the post-season, posting a perfect 4-0 record with 31 K's in 40 1/3 innings. Koosman was the left-handed compliment to righty Tom Seaver on the Mets for more than a decade. He retired with 222 wins and more than 2,500 strikeouts.
#36 (1967-1983), #37 (1984), #24 (1984-1985)
Koosman and Steve Carlton teamed as the Phillies' fifth starter in 1985. The following season, Mike Maddux replaced Koosman in that role.
Koosman won 17 games during the regular season, when he fashioned a 2.28 ERA, which ranked fifth in the circuit. In the post-season, the lefty won Game Two of the LCS against the Braves, took Game Two of the World Series, and was on the mound for the final out of the Series in Game Five.
On the final day of the 1979 season, Koosman shut out the Milwauke Brewers, 5-0 for his 20th win. The shut out was the Brewers only one of the entire season, preventing them from joining the 1932 Yankees as the onlt teams to not be whitewashed during a season.

Koosman was a terrible hitter: 52% of his outs were via strikeout.
On August 19, 1983, in the second game of a doubleheader in Texas, Koosman won his 200th career game, pitching the White Sox to a 6-1 victory.
Koosman twice fanned 15 batters in a game: first on May 28, 1969, in ten innings against the expansion Padres; and again on June 23, 1980, against the Royals in a 4-1 victory. Koosman struck out ten or more batters in a game twenty times.
Koosman holds New York Mets franchise records for most career starts by a lefty (346), and most starts in a season by a lefty (35 in 1973 and '74). He is also tied for most consecutive complete games (eight in 1976), and tied for most innings pitched in one season by a lefty (265 along with Jon Matlack in 1974.)
