Rays prospect Jose De Leon was diagnosed with a torn right UCL and could be facing season-ending surgery.
A tweet from the club on Wednesday said its No. 26 prospect will get a second opinion from Dr. James Andrews, the noted Tommy John surgery specialist. Surgery could sideline the 25-year-old for a year.
Top Rays prospect Brent Honeywell tore the UCL in his pitching elbow and underwent Tommy John surgery last month.
De Leon had appeared in a pair of Spring Training games for the Rays -- he's struck out two and allowed a pair of runs in two innings.
