Branden Dawson scored a career-high 26 points to help fourth-seeded Michigan State fend off a wild Harvard rally Saturday for an 80-73 victory in the NCAA tournament.
The 12th-seeded Crimson (27-5) trailed by 16 early in the second half but took a 62-60 lead when Laurent Rivard hit a 3-pointer with 7:12 remaining. Travis Trice answered with a 3 of his own on the next possession and the Spartans (28-8) never trailed again.
Michigan State made its 12th Sweet 16 in the last 17 years. Gary Harris had 18 points and five assists for the Spartans.
Wesley Saunders led Harvard with 22 points.
Florida 61, Pittsburgh 45: Scottie Wilbekin scored 21 points and top-seeded Florida beat Pittsburgh, advancing to the Sweet 16 for the fourth consecutive year.
Patric Young added seven points and eight rebounds for the Gators, who extended their school record for consecutive wins to 28 with the victory in the South Regional.
Coming off a lackluster performance in its NCAA opener, Florida (34-2) played with considerably more energy and intensity against the Panthers (26-10).
Wilbekin and Young spearheaded the effort. The Gators were 5 of 20 from behind the arc, with at least five of those rimming in and out.
Connecticut 77, Villanova 65: Shabazz Napier scored 25 points in leading Connecticut to a win over second-seeded Villanova in the third round of the NCAA tournament.
Villanova became the highest seed to be knocked out of the tournament so far, and the Wildcats' loss came on the heels of another upset in Buffalo. The game was played immediately after Dayton, the South Region's 11th seed, beat third-seeded Syracuse.
Seventh-seeded Connecticut (28-8) advanced to New York City this week, when they'll play the winner of today's third-round game between third-seeded Iowa State and sixth-seeded North Carolina.
Ryan Arcidiacono scored 18 points for Villanova (29-5) in a matchup of two former Big East rivals.
Dayton 55, Syracuse 53: Dyshawn Pierre scored 14 points and Jordan Sibert, held scoreless in the first half, hit a key 3-pointer with 47.7 seconds left as Dayton stunned Syracuse to earn a spot in the Sweet 16 for the first time in three decades.
Syracuse was in position to pull it out, but freshman Tyler Ennis missed two jumpers that would have given the Orange the lead in the final seconds.
Dayton (25-10), the 11th seed in the South, advanced to the regional semifinals this week against No. 2 seed Kansas or 10th-seeded Stanford.
The third-seeded Orange (28-6), who finished second in their first year in the Atlantic Coast Conference, struggled all game against the swarming Dayton defense.
Louisville 66, Saint Louis 51: Luke Hancock scored 21 points and defending national champion Louisville shrugged off a cold shooting performance to advance to the Sweet 16 for the third straight year.
The fourth-seeded Cardinals (31-5) shot under 45 percent, had 19 turnovers and only got 11 points from star Russ Smith. It didn't matter, with the fifth-seeded Billikens (27-7) going 0 for 15 from 3-point range and struggling to take care of the ball.
Saint Louis, which has never been to the Sweet 16, lost in the third round of the tournament for the third consecutive year. Dwayne Evans led the Billikens with 16 points and Atlantic 10 player of the year Jordair Jett finished with 15.
Michigan 79, Texas 65: Nik Stauskas had 17 points and eight assists to lead Michigan to the Sweet 16 for the second straight year.
Jordan Morgan added 15 points and 10 rebounds as No. 2 seed Michigan (27-8) advanced to the regional semifinals in Indianapolis.
Glenn Robinson III, a Lake Central grad, had 14 points each for Michigan, while Spike Albrecht, a Crown Point grad, added five points, three rebounds and a steal.
Isiah Taylor scored 22 points for Texas on 8-for-22 shooting. The seventh-seeded Longhorns (24-11) outrebounded the Wolverines 41-30, but got off to a slow start and never recovered.
Wisconsin 85, Oregon 77: Ben Brust hit a go-ahead 3-pointer with 1:07 left and second-seeded Wisconsin overcame seventh-seeded Oregon to reach the Sweet 16.
Brust's clutch 3 from the corner gave the Badgers (28-7) the lead for good in a heavyweight fight of an NCAA tournament game.
Traevon Jackson followed with three free throws, but missed one with 21 seconds left to give the Ducks (24-10) one more chance to tie trailing by three.
Oregon gave it to Joseph Young, who had made big shots all night and scored 29 points. But he missed a rushed 3 from the wing and the Badgers sealed it at the foul line as an arena filled with Wisconsin fans broke into a deafening roar.
San Diego State 63, North Dakota State 44: Xavier Thames scored 30 points and San Diego State reached the round of 16 for the second time in school history.
The fourth-seeded Aztecs (31-4) now get to make the short drive up the highway to Anaheim, Calif., where they will face No. 1 seed Arizona or eighth-seeded Gonzaga in the West Regional semifinals.
Thames, who was 9 of 19 from the field, had five assists and ended the comeback hopes of the Bison with a six-point spurt late in the second half.
Dwayne Polee II was the only other San Diego State player in double figures with 15 points.
Kory Brown led the 12th-seeded Bison (26-7) with 13 points, but the best shooting team in the country shot only 31.9 percent.
