Draymond Green sends Michigan State past St. Louis, 65-61 Draymond Green grabbed a mop in the final minute and helped sweep sweat off the court. Moments later, Michigan State finally brushed aside St. Louis. Green had 16 points and 13 rebounds and set up Keith Appling's crucial three-point basket with 1 minute 34 seconds to play, giving the top-seeded Spartans a 65-61 victory over the Billikens on Sunday at Columbus, Ohio, and a spot in the round of 16. Michigan State (29-7) will play fourth-seeded Louisville (28-9) in a West Regional semifinal Thursday at Phoenix. Appling scored 19 points to help the Spartans, who had to scrap their way past the ninth-seeded Billikens (26-8). St. Louis controlled the tempo but never got a complete handle on Green, Michigan State's superb senior, who had six assists. Kwamain Mitchell scored 13 points and Brian Conklin had 11 for St. Louis. St. Louis trailed, 55-51, when Green drove the left side and rifled a two-handed overhead pass to Appling in front of Michigan State's bench. The guard had a three-point shot drop in, but only after it hit both sides of the rim and backboard. Appling's two free throws gave Michigan State a 63-55 lead, but Cody Ellis and Mike McCall Jr. made three-pointers in the final 30 seconds for St. Louis and Michigan State's victory wasn't assured until Mitchell's three-pointer with three seconds left was short. Florida 84, Norfolk State 50: No big upset this time. Kenny Boynton and Florida were just too good for surprising Norfolk State. Boynton scored 20 points and the balanced Gators defeated the 15th-seeded Spartans, 84-50, at Omaha to reach a regional semifinal for the second consecutive year. Norfolk State (26-10) was trying to become the first 15th-seeded team to reach the round of 16. Florida (25-10) put a quick end to that idea, making five three-point baskets during a 25-0 run that made it 29-6 midway through the first half. The seventh-seeded Gators made it to a regional semifinal for the sixth time in 12 NCAA tournament appearances under Coach Billy Donovan. They will play third-seeded Marquette (27-7) on Thursday in Phoenix. Erving Walker finished with 15 points for the Gators. Bradley Beal scored 14, Mike Rosario had 12 and Erik Murphy had 10. The Spartans shot 27% and made four of 24 three-point shots. Boynton, who had made only four of his previous 21 three-point shots, connected on one to start Florida's decisive run. The big surge featured the frenetic tempo at which Florida likes to play. The Spartans missed 10 shots in a row, and each time the smaller Gators got the rebound, they pushed the ball quickly up the court.
