Tyler Skaggs was pulled from Thursday night’s game against the Baltimore Orioles in the fifth inning because of a forearm strain that will probably send the Angels left-hander to the disabled list for the second time this season.

But Skaggs, 23, is confident that the injury is not serious, a huge relief to the Angels considering how many pitchers have undergone elbow reconstruction surgery this year.

“The doctor said the UCL [ulnar collateral ligament] is fine,” Skaggs said after the Angels’ 1-0, 13-inning win over the Orioles. “At the moment, it’s not looking bad. I have full range of motion, and the tests went well. We’ll see tomorrow, though. It’s not feeling too bad right now.”

Skaggs, who has never injured his arm before, will undergo an MRI test Friday. He said he was injured when he “over-pronated” his arm on a changeup that he threw to strike out Delmon Young to start the fifth.

“The flexor tendon tightened up on me, and I couldn’t really feel my fingers,” he said. “I tried to pitch through it.”
