It was the fourth time this season Hooper, who has yet to make a 2-point field goal, has hit seven or more 3s in a game. He is averaging 3.6 3-pointers per game ranking him fifth in the NCAA.
The Golden Grizzlies led just 75-73 after Milwaukee's Austin Arians made a layup with 2:06 left. But Oakland scored the next five points, including Hooper's final trey, to extend the lead back to 80-73 with only 36 seconds to go.
Jordan Johnson had 20 points and nine assists for the Panthers (14-7, 5-3). Arians and Lyle had 13 points apiece.
