Next on my list comes from less than one year ago: the 2011 Super Regional vs. Florida when State pulled out a last at-bat victory in dramatic fashion on Nick Vickerson's 2-run homer.
MSU was coming off the worst stretch in its history - three consecutive losing seasons. Finally, State got back to the Regionals in 2011 and were able to sweep through Georgia Tech's turf on their way to face SEC-foe, #2 Florida. The Gators were the heavy favorite, as MSU had well overachieved by getting to this point.
Florida won Game 1 of the series 11-1, and they never trailed throughout Game 2. Nick Routt pitched the first three innings for MSU before giving way to Caleb Reed in the 4th. Reed pitched a great game, getting the win after allowing only one run to the Gators' great offense. That run came in the top of the 8th, right after State had tied the game at 2-2 half an inning prior.
Down 3-2 in the bottom of the 9th, Nick Vickerson came up with no outs and a runner on 1st. He ripped the first pitch he saw over the left-centerfield fence...

Game 3 was a wild affair. Florida got out to a 4-0 lead only to lose it via a 3-run Vickerson homer in the 4th and RBI hits from Vickerson and Brent Brownlee in the 6th. MSU was up 6-4 until UF hit a 3-run shot themselves to take the lead back. The final score was 8-6 and the Gators advanced to the College World Series. There Florida would finish as the national runner-up, losing to South Carolina in the championship series two games to zero.
