Ralston Burdett Hemsley (June 24, 1907 – July 31, 1972) was an American professional baseball player.

[2] At the end of the 1932 season, Hemsley was traded to the Cincinnati Reds along with Johnny Moore, Lance Richbourg, and Bob Smith for Babe Herman.

[2] He played well for two more seasons for the Browns, but a batting average of .222 in 1937, as well as a suspension for violation of team rules on July 2, 1937,[3] led to a trade on February 10, 1938.

[5] His consistency in the 1940 season saw him lead the American League catchers with a .994 fielding percentage, and led to a couple MVP votes as well as his fourth All-Star appearance.

When Dickey's backup, Buddy Rosar, left the team without permission to take examinations to join the Buffalo police force and, to be with his wife who was about to have a baby, Yankees manager Joe McCarthy signed Hemsley to be the second string catcher, relegating Rosar to the third string position.

[7][8] Hemsley hit safely in his first six games as a Yankee,[7] and raised his average back to nearly .200 by season's end.

[2] Hemsley led American League catchers twice in assists, once in fielding percentage, once in baserunners caught stealing and once in range factor.

[11] After retiring, Hemsley operated a real estate office in Langley Park, Maryland, was a coach for the Philadelphia Athletics (1954) and Washington Senators (1961–62) and managed in the minor leagues.

He was selected Minor League Manager of the Year by The Sporting News in 1950 while serving as pilot of the Columbus Red Birds.
