Michigan led by 15 in the opening minute of the second half, but the Tritons reeled off 11 straight points to pull within three.

Donaldson’s 3-pointer with 16:32 left was the Wolverines’ first basket of the second half, but Kapic answered with one from deep to make it 45-42. After two missed free throws, Gray’s layup made it a one-point game.

Michigan went on an 11-2 run, but UC San Diego rallied to cut it to 61-56.

Gayle and Donaldson each split a pair of free throws, allowing the Tritons to tie it at 63 on McGhie’s 3-pointer with 3:05 left.
