My WAR calculation is a combination of Baseball-reference and Clay Davenport; I believe it to be the "best" WAR number available for historical comparison. 8 WAR is an MVP quality season. The record is pythagorean adjusted for 162 games.

RP Ken Trinkle -.05-WW2 was not kind to the Giants, even its ending doesn't raise the club out of last place. This is the year Durocher said "nice guys finish last" about Ott, who got thrown out of both ends of a doubleheader in June. Schumacher and Bartell both retire. So does Rucker, who finishes his career with 2700 PA and a negative WAR; he's the worst Giants player of the first 64 years of the club's existence.
