Piercy has been the only true upset today so far.
I was in the air about Garcia/Kuchar. That one could have went either way. I'm also not involved in this one, I must have missed it, but have another bracket going.
I chose Poulter because I thought it was risky enough that not many would have chosen him (I figured Tiger/Rory would suck up the majority), but given his performance in match play in the past, he's always a threat to win in this format.
