New York Mets medical director Dr. David Altchek operated on Wentz on Tuesday in West Palm Beach, Florida. Detroit said Wednesday that Wentz is expected to return in 14-16 months.
Wentz, 22, was a non-roster invitee at big league spring training this year. He is the No. 8 prospect in the Detroit organization, according to rankings on MLB.com.
Detroit acquired him last July 31 in the deal that sent reliever Shane Greene to Atlanta. Wentz was 7-8 with a 4.20 ERA in 25 starts at Double-A last year.
