Betty Jane Cornett (November 24, 1932 – March 18, 2006) was an infielder and pitcher who played in the All-American Girls Professional Baseball League. Listed at 5' 5", 125 lb., she batted and threw right handed. After spring training camp, Rockford decided that Cornett was not ready for the league and sent her to the Springfield Sallies rookie touring team to acquire more experience. In 1951 she was promoted to the Kalamazoo Lassies and was dealt to the Battle Creek Belles before the 1952 season.
