Florida head coach Pat McMahon –
"This is tournament time and this is a fun event. This was just another great example of a great college baseball game. Both teams battled hard and we were fortunate to pull out another one run victory. It was just a great felling this morning to wake up and put on my uniform to play baseball."
"Jonathan Tucker put us in position to win with his big hit and then we took advantage of that. Jonathan was running hard all the way. It was a great effort play on both sides of the field and when you have great effort good things are going to happen."
Florida junior Jonathan Tucker -
On scoring the winning run "I just hit the ball squarely on the bat and started to run. I honestly thought the ball was caught, but I just kept running as hard as I could and I kept looking for Coach Slater's signals on third base. It was a great feeling to take the lead with Darren on the mound."
