TCU sophomore forward Kouat Noi tried to quiet the crowd, placing his finger to his lips, on back-to-back 3-pointers in the closing minutes. Noi scored a career-high 30 points on 8 of 12 3-point attempts.
James and Doolittle responded, only for TCU guard Alex Robinson to sink a 3-pointer and tie the game 74-74 with 16 seconds left.
Doolittle would decide the ending.
“Coming out of the timeout, I knew the play was called for me,” he said. “It was really just a read because we had Christian (James) in the corner. If I drove and his man helped, it was going to Christian. Once I took my first dribble, I realized they weren’t going to help, so I just went from there.”
Doolittle’s shot swirled once around the rim before dropping in.
He stuck his tongue out as he backpedaled down the floor. McNeace picked him up after the game as a smile spread across Doolittle’s face.
The Sooners (13-3, 2-2 Big 12) protected home court, leveling their record in conference play on a day when every other Big 12 game was won by the visitor.
Oklahoma returns to Lloyd Noble Center to face Kansas State at 6 p.m. Wednesday.
