Trailing 64-61 late in the second half, San Francisco (3-2) tied the game on a Dickerson 3-pointer and then took the lead with 2:48 remaining on a 3-pointer by Mark Tollefsen. The Dons held their advantage despite going just 1 of 7 from the free throw line in the final minute of the game.
Three San Francisco players joined Pinkins in double digits: Dickerson, with 17 points and 12 rebounds, Tollefson with 14 points, and Avry Holmes with 13. The Dons shot 54.5 percent from the field and out-rebounded the Grizzlies 35-25.
Kareem Jamar led Montana (1-2) with a game-high 25 points and eight assists, but missed a jumper at the buzzer that would have won the game.
