Chinanu Onuaku had 18 points and 10 rebounds as Louisville ground down No. 20 Pittsburgh for a 59-41 victory Thursday night.

The sophomore center had his fourth consecutive double-double to go with three blocks. Damion Lee also scored 18 points for the Cardinals (14-3, 3-1 Atlantic Coast Conference).

Louisville led 20-17 at halftime, the lowest halftime total for both teams this season. Both teams were 1-of-11 (9 percent) from 3-point range. Louisville had a 34-20 advantage on points in the paint.

Louisville used a 7-0 run to stretch the lead to double digits with 16:07 left, capped by Ray Spalding's reverse layup. The Cardinals led 33-23 when Pitt's Sheldon Jeter, a 93 percent free throw shooter, missed three straight from the line. That helped Louisville to stretch its lead to 40-25 with 9:33 remaining before Pitt began clawing back. Ryan Luther's steal and dunk with 4:54 remaining cut the lead to nine before Louisville went on an 11-0 run.

Pitt (14-2, 3-1) saw its 10-game winning streak snapped in by far its worst outing of the season. Michael Young led the Panthers with 18 points and eight rebounds.
