Sounds like Ryu came out after 80 pitches because of some forearm tightness.

But back in the dugout, Ryu told Montoyo and his pitching coach, Pete Walker, that he was experiencing forearm tightness after throwing a series of sliders, a pitch he doesn’t typically use, throughout his outing. And that was the end of that. Ryu exited the game, while Montoyo turned to Trevor Richards, Tim Mayza, and Adam Cimber, who recorded the final nine outs with little trouble.
