Whoever the main announcer is. I guess Thorne. After Pedroia singled they just realized Meek wasn't pitching anymore and were like "oh, this is actually Webb pitching... Ryan Webb"
I just don't get it. Pitch didn't look intentional at all, and you also usually don't hit a guy who hits .200 when he's trying to bunt in tied game in 7th inning. Overreaction by Ross IMO
