Tris Speaker holds the major league record for turning the most unassisted double plays during a career with six. In the National League, no outfielder has ever had more than two during their career.
On May 31, 1931, Adam Comorosky of the Pittsburgh Pirates turned an unassisted double play. On June 13, 1931, he turned another thus becoming the first and only National League outfielder in Major League history to have two outfield unassisted double plays during the same season.
In 1928, Charlie Jamieson of the Cleveland Indians became the only outfielder to ever start two triple plays during a single season — one on May 23, 1928 & the other on June 9, 1928.
