Aubrey Lee ("Yo-Yo") Epps (March 3, 1912 – November 13, 1984) was a Major League Baseball catcher.
Epps underwent a tonsillectomy in mid-October 1935, expecting to see his health improve towards earning a spot as the Pirates' starting catcher in the 1936 season.
However, Epps experienced hemorrhages that forced him back into the hospital in critical condition two days later, with his breathing impairment leading to pneumonia and his placement under an oxygen tent.
[4] By the end of December 1935, Epps had been released from the hospital and was recovering in his home in Memphis, Tennessee, with his doctor telling him that he should avoid spending time outdoors until warmer weather arrived.
[5] By the time the Pirates players reported to San Antonio, Texas for spring training in March 1936, Epps was on the team's roster, hoping to make a comeback as catcher, having recovered from his pneumonia.
