Dodgers phenom Dustin May will undergo Tommy John surgery to repair damage to the UCL in his right elbow, the club announced on Monday. The surgery will be performed on May 11 by Dr. Neal ElAttrache.

May landed on the injured list after leaving early during Saturday’s 6-5 loss to the Brewers. May was in the middle of an at-bat with two outs in the second inning when he visibly winced and signaled for the athletic trainer after throwing a pitch. Manager Dave Roberts described it as a “shooting sensation” in the right-hander’s pitching elbow.

May, who finished fifth in National League Rookie of the Year voting last fall, has pitched in parts of the last three seasons for the Dodgers. He is 1-1 with a 2.74 ERA in five starts this season.

San Diego Padres left-hander Adrian Morejon needs Tommy John surgery, the team said Tuesday.

Although no date has been set for the operation, it will be performed by Dr. Neal S. ElAttrache, head physician for the Los Angeles Dodgers.

Morejon came out of his second start of the season, at Texas on April 11, after throwing just 16 pitches in two-thirds of an inning. He had no record and a 3.86 ERA in 4⅔ innings.

Mariners left-handed starter James Paxton was forced to leave his start last Tuesday after just 21 pitches, and it did not look good. He was squeezing his hand on the mound with an extended arm with a lot of times means an elbow issue. Sure enough, he will be undergoing season-ending surgery, manager Scott Servais told reporters Tuesday (via Corey Brock). Previous reporting indicates the procedure will be Tommy John surgery.

Since he was on a one-year deal and this ends his season, Paxton will head to 2022 as a free agent, likely looking to sign with a team who could have some patience before giving him a shot at a rotation spot around the middle of the season.

Paxton, 32, has always flashed big upside when on the mound, but he’s also battled injuries through much of his MLB career. His career-high in starts in a season is 29 and his top mark in innings pitched is 160 1/3. He’s never had Tommy John surgery, though.
