PEORIA, Ariz. -- San Diego Padres right-hander Dinelson Lamet left Sunday's spring training start with an elbow injury, possibly jeopardizing his chance to pitch this week in the regular season.
Padres manager Andy Green said he didn't have a medical update on Lamet's condition after an 11-7 loss to Seattle.
"Hopefully he's not out for long, but usually when you walk off the mound and your elbow hurts, it's not a good thing," Green said.
The 25-year-old Lamet made his fourth spring training start. He had been expected to be the second-day starter in the Padres' rotation after Clayton Richard opened Thursday at home against Milwaukee.
"He threw a slider and felt it," Green said. "It was the last or second-to-last pitch. Anytime you pull one of your main guys out of a game, at any time in spring training, it's concerning. The last tuneup outing before the season, it's very concerning. We'd love to have him, he's a big part of what we plan on doing."
Lamet exited in the top of the second inning after a pitch he threw got away for a passed ball. His start lasted 1 1/3 innings and he allowed an earned run on two hits with two strikeouts.
Last season, Lamet went 7-8 in 21 starts with a 4.57 ERA. He struck out 139 in 114 1/3 innings.
This spring, Lamet posted a 3.75 ERA in 12 innings.
