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.

The Giants make up a 13 game mid August deficit, and then win a three game playoff against the Dodgers on Thomson's three run 9th inning homer. Willie Mays begins his assault on the all time Giants WAR mark, still held by Mathewson at that time. Stanky moves on after two terrific Giants seasons.
