James F. Macullar (January 16, 1855 – April 8, 1924), also known as "Little Mac", was an American Major League Baseball player from Boston, Massachusetts. He played mostly at shortstop, but did play many games in center field, for three different teams in two leagues. He holds the record for career games played at shortstop by a left-handed thrower, at 325, and is the only lefty to ever play more than 250 games at that position. Nicknamed "Little Mac", due to his small stature (5'6", 155 lbs), he was briefly a player-manager for the Syracuse Stars in 1879. Finishing with a 5-21 record, he never managed again.
