Stanky was famous for his ability to draw walks; he drew 100 walks each in 6 different seasons, twice posting 140. In 1946, Stanky hit just .273, but his 137 walks allowed him to lead the league in OBP with a .436 figure, edging out Stan Musial—who led in 10+ batting departments. His best season was probably in 1950 with New York, when he hit an even .300 and led the league in walks (144) and OBP (.460). On August 30 of that year, he tied a Major League record when he drew a walk in seven consecutive plate appearances. He accomplished the feat over a two-game span.
Leo Durocher, who managed him with the Dodgers and Giants, once summed up Stanky's talents: "He can't hit, can't run, can't field. He's no nice guy... all the little SOB can do is win." Yankees shortstop Phil Rizzuto still complained years later about a play during the 1951 World Series where Stanky kicked the ball loose from Rizzuto's glove. Whenever he was the runner on third base, Stanky developed the habit of standing several feet back of the bag, in left field. If a fly ball was hit, he would time its arc, then take off running so as to step on third base just as the catch was being made. In this way he would be running towards home at full speed from the beginning of the play, making it almost impossible to throw him out. This tactic was made illegal following the season. Stanky was also (in)famous for what came to be called "the Stanky maneuver", where he would take advantage of his position on second base to distract opposing batters by jumping up and down and waving his arms behind the pitcher. When Stanky was manager of the Cardinals, he also delayed games which might be called for darkness or curfew, by going to the mound after every pitch to confer with his pitcher, which resulted in the one-trip-per-inning rule.
Stanky was a contributor to the breaking of the color barrier in 1947. When Jackie Robinson joined the Dodgers, he was treated harshly and faced discrimination. For a while, this had no effect on Stanky. Later, though, he could take no more. During a game against the Phillies, he began to yell back when they tried to discriminate against Robinson. It was not long after he did that the other Dodgers began to stand up for Robinson.
