May, who was the frontrunner for the fifth spot in the rotation, remains likely to undergo season-ending Tommy John surgery, but he wants to see if there are alternatives, as other pitchers such as Masahiro Tanaka and Garrett Richards have avoided the surgery with platelet-rich plasma injections and stem-cell injections.
May, though, is believed to have a full tear of the ligament, which would require surgery. It's generally a 12-month rehab process, so the earlier May undergoes the operation, the more likely he would be available for Opening Day 2018.
Worth noting
