Until that run, the Grizzlies had been 1 of 15 from 3-point range and Bader had been 0 for 8. Bader's first 3-pointer gave the Grizzlies their first lead of the game at 37-35 with 13:42 left and Oakland never trailed from there.

Nick Kellogg led Ohio (6-2) with 18 points but fouled out with 2:26 left. The Bobcats had closed the gap to 53-64, but allowed Oakland to go on a 10-2 run after Kellogg's departure.
