Would it be fair to say that Quinn is merely an above-average defensive player, not anything special? I mean, he can handle the position and he is fast, but not sure about his instincts (granted he doesn't have hundreds of innings of practice) or his arm.
It looks like the ball hit Guerrero's bat twice, I think that's why it was not an error on Quinn. He'd probably reacted to the first shot and the actual hit was also-broken bat, which can be hard to judge. Heck, is that technically a foul ball?
Romero was warming up. He's about to become a Phillies cult hero regardless of performance.
