Michael Henry McGeary (February 12, 1851 – After 1910) was an American Major League Baseball player. He played mainly infield positions during his 11 league seasons, which included stints for seven different teams in two leagues. Three of those teams employed him as player-manager.
McGeary was a native of Philadelphia. He made his professional debut at 19, as the regular catcher for the Troy Haymakers in 1870, the last season of the National Association of Base Ball Players. The NABBP had first permitted professional clubs for the 1869 season and the "Haymakers" had been one of twelve pioneers. Formally they were the Union baseball club of Lansingburgh, New York, a city neighboring Troy and subsequently annexed by it.
While the team played 25 professional matches in 1870 (with 11 wins and one tie), McGeary played in 37 of all 46 games on record. He was a little below average as a batter in the company of his teammates.  It was a solid team in the professional class. Seven of the including McGeary were remained together when the club participated in the first professional league during 1871.
His league statistics seem to show that Mike was a solid ballplayer, but rumors that he threw games persisted throughout his career, though never substantiated. He was suspended by the St. Louis management for allegedly "throwing" a game on May 27, 1876. The game took place against the New York Mutuals at the Union Grounds, and Mike had made four errors.
Little is known about Mike McGeary after his baseball career. The best resources may only be census records. The last of these records appear to be from 1910, which hints that he may have died between 1910 and 1920.
