CHICAGO (AP) — Zoom Diallo had 22 points and 11 assists and scored the go-ahead basket in overtime as Washington defeated USC 83-79 in the second round of the Big Ten Tournament on Wednesday.

The 12th-seeded Huskies (16-16) will take on fifth-seeded Ohio State in a quarterfinal on Thursday.

Diallo scored 15 points over the second half and overtime despite staying on the floor after picking up his fourth foul with nearly 13 minutes left in regulation. Quimari Peterson made five 3-pointers for his 15 points and Wesley Yates III also scored 15. Hannes Steinbach, who scored 24 and 22 points in Washington’s two regular-season wins over the Trojans, finished with 10 points and 11 rebounds.

Kam Woods scored 24 points with seven assists for the 14th-seeded Trojans (18-14), who lost their eighth straight. Jacob Cofie added 14 points, Jordan Marsh had 13 and Ezra Ausar and Ryan Cornish 10 each.

Diallo’s bucket with 2:18 left in overtime gave the Huskies the lead and Peterson added a 3-pointer with a minute to go. Woods completed a three-point play to get the Trojans within a point and forced a turnover by Diallo with 24.2 seconds left. But Woods missed on a drive and fouled Diallo, who made two free throws for an 82-79 lead. USC called timeout with eight seconds remaining but Marsh missed an awkward 3 and Hannes Steinbach made 1 of 2 free throws.

USC led by as many 13 in the second half then Washington went on a 20-4 run to go up 64-61 with six minutes left in regulation. The game was tied at 71 with a minute left but Diallo and Woods missed jumpers on their teams’ final possessions.
