On March 2, 1886 — 1886 – The American Association meets and overrules president Denny McKnight (also owner of the Pittsburgh Alleghenys club) and suspends second baseman Sam Barkley for signing with Pittsburgh before the dispute over his sale is settled. The AA adopts new rules. The number of balls needed for a walk is reduced from seven to six; the pitcher’s box is one foot deeper, giving the pitcher seven feet behind the 50-foot front line in which to execute his delivery; stolen bases are adopted as an official statistic, although the definition is rather vague initially.
