In 1996 Ivan Rodriguez of the Texas Rangers set the Major League record for doubles hit by a catcher during a season with forty-five. The record is five more than the National League record and he actually had forty-seven doubles over the course of the full season, but two were hit while playing at the designated hitter position.
Did you know that in 1970 Dal Maxvill of the St. Louis Cardinals set the Major League record for fewest doubles hit in a complete season (minimum of one-hundred fifty games played) with only five two-baggers?
Hank Borowy (Chicago [NL] May 5, 1946 - 7th Inning), Fred Goldsmith (Chicago [NL] September 6, 1883 - 7th Inning), Ted Lyons (Chicago [AL] July 28, 1935 - 2nd Inning), and Joe Wood (Boston [AL] July 4, 1913 - 4th Inning) are the only pitchers to hit two doubles during the same inning.
