Florida guard Mike Rosario stood near midcourt, smiling, shaking hands and high-fiving his teammates as the final seconds ticked off the clock of a win over Minnesota that had started as a laugher and turned into a grinder. Rosario and his teammates could finally relax: The Gators were on their way to the NCAA tournament round of 16 for the third consecutive year. Rosario scored 25 points, most of it coming on six 3-pointers, and No. 3 seed Florida used an overpowering first half to earn a 78-64 win Sunday over No. 11 seed Minnesota in the third round of the South Regional.
