Mississippi guard Terrico White, struggling with inconsistent shooting for most of the season, picked the best time of the year to regain his touch.
White scored 21 points, including 3 of 4 from 3-point range, as the Rebels defeated Memphis 90-81 Friday in the second round of the National Invitation Tournament.
Ole Miss advanced to the quarterfinals and will host the Texas Tech-Jacksonville winner on Tuesday.
"It feels good to see my shots going down again," said White, who scored 27 points in an NIT opening-round win against Troy. "My confidence is back up and so is the team."
Never miss a local story.

Memphis (24-10) never got closer than six points again.
The Tigers had five players score in double figures. Will Coleman had 15 points and a game-high 14 rebounds. Angel Garcia scored 17 points, Wesley Witherspoon had 13 points, Doneal Mack had 12 and Elliot Williams added 11.
