Buddy Hield scored 14 of his 19 points after halftime, including consecutive 3 pointers that put No. 1 Oklahoma ahead to stay in an 82-72 victory at No. 13 Baylor on Saturday.
Hield, the Big 12 scoring leader, missed the final 9 minutes of the first half with two fouls.
Oklahoma (16-2, 5-2 Big 12) matched its season high with 16 3-pointers, including five by Jordan Woodard when he had all 20 of his points in the first half.
The Sooners reached No. 1 for the first time since 1990 this week, then lost 82-77 at No. 19 Iowa State on Monday night. But they rebounded big by ending Baylor's 15-game home winning streak to match the Bears (15-4, 5-2) for the Big 12 lead.
Baylor opened the second half with an 11-4 run, tying it at 41-all with 17:39 left on Ish Wainright's 3-pointer before Field's go-ahead shots.
