You spend all this time studying and anticipating a postseason match-up -- and Cain and Cueto were about as evenly matched as two pitchers were going to get this postseason -- and then this happens. Johnny Cueto, the Reds' ace, left the game after throwing just eight pitches.
I'm not a doctor, but I don't mind pretending to know what I'm talking about. And it looked like an oblique tweak to me, though it could have been the back. Update: back spasms, and he's day-to-day. And on both radio and TV, the announcers are speculating the injury might have started two pitches prior, when Cueto aborted his delivery when Angel Pagan called time and stepped out of the box:
To home-plate umpire Phil Cuzzi's credit, he did not call time. But Cueto still stopped short in his delivery, and two pitches later, he called for the trainer.
Reliever Sam LeCure is in for the Reds, and he retired Marco Scutaro and Pablo Sandoval on 5-3 groundouts to end the inning.
