Left-hander John Lamb has become the latest Angel to require Tommy John surgery, the club announced on Saturday.
Lamb, 27, was placed on the disabled list on Wednesday with left elbow inflammation, one day after making a start against the Red Sox in Boston in which he gave up five runs (three earned) on six hits and two walks over 1 2/3 innings. It was just his third start with the big league club after being called up on June 16. An MRI revealed the torn ulnar collateral ligament. Dr. Neal ElAttrache will perform the procedure in Los Angeles.
Lamb, who before this month hadn't appeared in the Majors since July 2016 with the Reds, had a resurgence of sorts with Triple-A Salt Lake over 13 starts that, coupled with the Angels' rotation attrition, created an opportunity at the Major League level.
The Angels also announced that right-hander Jake Jewell underwent successful left ankle surgery on Friday and will be out for the remainder of the season. Third baseman Zack Cozart also underwent a successful repair of his left labrum tear, and is expected back in six to eight months.
Ohtani faces pitchers
Shohei Ohtani took batting practice and participated in a simulated game on Saturday at Angel Stadium. Ohtani, who is solely focused on offense while he returns from a right UCL sprain, had 10 at-bats in the simulated game and ran in the bases.
Ohtani was placed on the disabled list on June 8 (retroactive to June 7), and there's no official timetable for his return, but the Angels are hoping he could return as a batter before the All-Star Game.
"[We] evaluate every day," manager Mike Scioscia.

Richards makes rehab start
Pitcher Garrett Richards, who's on the DL retroactive to June 14 with a left hamstring strain, threw 3 1/3 innings in his first rehab start with Class A Advanced Inland Empire on Friday.
Richards gave up five runs on seven hits and took the loss in a game against Rancho Cucamonga. Scioscia said the Angels have to wait and see how the right-hander rebounds.
"Felt good physically," Scioscia said. "All his stuff looked good. Just lost some of his command as the outing went on, but physically he felt good."
Worth noting
• The Angels optioned outfielder Michael Hermosillo to Triple-A Salt Lake and recalled infielder Kaleb Cowart from the same team. Scioscia said that Cowart's versatility gives them more ways to do more things later in the game.
• Saturday marked Scioscia's 3,000th game as the Angels' manager. He's the sixth manager in Major League history to reach that milestone with one team, but the skipper did not even realize he was at that number.
"It's 3,000, one game at a time," he said with a smile.
