Michigan State is on to the Sweet 16, but it was hardly smooth sailing.
The Spartans withstood a big second-half run from Harvard to win 80-73 and move on to the Sweet 16 for the third straight year.
Branden Dawson had 20 first-half points to tie a career high before the break. He finished with a game-high and career-high 26 points.
The Spartans led by 12 at halftime, but the Crimson used a 16-2 second-half run to tie the game 55-55 with a Wesley Saunders layup.
Harvard's Laurent Rivard gave the Crimson a 62-60 lead with 7:11 to go. Travis Trice came right back with a 3-pointer of his own to give MSU the lead again and the Spartans wouldn't trail.
Gary Harris and Denzel Valentine followed with 3-pointers to ensure a Michigan State victory.
The Spartans will meet the winner of No. 1 seed Virginia and No. 8 Memphis on Friday in New York.
It is the 12th Sweet 16 appearance for the Spartans in Tom Izzo's 17 consecutive NCAA Tournament appearances.
Branden Dawson fuels Michigan State with 20 first-half point, but Harvard made it tight in the second half with a strong 14-2 run.
