Ruth Elizabeth "Tex" Lessing (August 15, 1925 – October 26, 2000) was an American female catcher who played from 1944 through 1949 in the All-American Girls Professional Baseball League.

Respected for her solid skills behind home plate, including a strong and accurate arm, Lessing also was renowned for her fiery and competitive spirit.

She played over 100 games during four straight seasons, was selected to the All-Star Team three consecutive years, and set several all-time, single-season records before suffering a career-ending shoulder injury that forced her to retire prematurely.

She graduated in 1944 and immediately joined the Minneapolis Millerettes, an expansion AAGPBL team managed by former big leaguer Bubber Jonnard.

[1][4][6] Lessing became a regular with Fort Wayne in 1945, appearing in 110 games and setting an all-time single season record for a catcher with a .982 fielding average.

She also hit .123 with 32 runs and 21 RBI, while the Daisies, with Bill Wambsganss at the helm, had a strong season debut, going 62–47 and finishing four and a half games behind first-place Rockford Peaches.

[1][3][4] Lessing became one of two hundred players to attend the first AAGPBL spring training outside the United States, which was held in 1947 in Cuba at the Gran Stadium de La Habana.

She is part of the AAGPBL permanent display at the Baseball Hall of Fame and Museum at Cooperstown, New York, opened in 1988, which is dedicated to the entire league rather than any individual player.
