In a match that lasted just over an hour, fan favorite Querrey was solid for most of the night. "I thought I played well, the best I've played so far...I had that mental lapse in the second set, but I was fortunate there. I can't afford to have that happen tomorrow, but all around it was pretty good. I've gotten a little better in each match, and I hope I can be even better tomorrow."
