TORONTO -- Right-hander Andrew Triggs was forced to leave the A's 10-5 win over the Blue Jays at Rogers Centre in the third inning Thursday with right forearm nerve discomfort.
Triggs will return to Oakland, where he will undergo an MRI. Once the club has more information, a decision will be made whether a roster move is necessary.
"I felt something the last pitch of the first, which was that changeup to [Yangervis] Solarte," Triggs said, "and it was kind of that tingling, shooting sensation from thumb to middle finger. Then a couple times in the second, so it didn't concern me all that much, then it was more frequent in the third."
Triggs fell behind in the count, 2-0, to Justin Smoak, when an A's trainer and the coaching staff came out to speak with him. In their conversation, Triggs appeared to be focusing on the area of his pitching hand. He then walked to the dugout with a trainer, ending his night.
"I've had the worst-case scenario, which is UCL, and I'm optimistic it's nothing related to that," Triggs said.
Over 2 1/3 innings, Triggs struggled with control, throwing 19 of 42 pitches for strikes and walking two batters. Santiago Casilla took over with a runner on first base and retired Smoak and Solarte to end the inning.
