Osby scored 18 points, including two key free throws with 16.9 seconds left, and Landon Milbourne added 16 points to lead five Maryland players in double figures and the Terrapins beat Georgia Tech 88-86 Saturday, ending the Yellow Jackets' three-game winning streak.
Maryland (14-8, 4-3 Atlantic Coast Conference), winning its fourth in five games and eighth of 10, also got 14 points apiece from James Gist and Eric Hayes.
Georgia Tech (10-10, 3-4) was led by Zach Peacock, who had 18 points. Matt Causey added 12 and D'Andre Bell had 11.
Georgia Tech got within 85-82 on six points in row by Peacock with 1:05 left, then got the ball back when Alade Aminu blocked a layup by Greivis Vazquez with 35 seconds remaining.
Anthony Morrow badly missed a 3-point attempt to tie it with 19 seconds left and Osby made a pair of free throws -- his only points of the second half -- for an 87-82 lead with 16.9 seconds left.
"If this was December, I would have taken him out and put a different guy in there to hopefully get him fouled while sitting Bambale," said Maryland coach Gary Williams.
"But that's where he's come with the free throws," added Williams.
The Terps, who went up 9-0 early, led 50-41 at the halftime.
