KANSAS CITY, Mo. (AP) Dash Harris and Khris Middleton drilled key 3-pointers in the last 4 minutes and Texas A&M hit 14 straight foul shots to beat Oklahoma 62-53 Wednesday night in a ragged opening-round match of the Big 12 tournament.

Eighth-seeded Oklahoma, trailing almost the entire second half, sliced the lead to 47-45 on Romero Osby's four free throws before Harris connected for his second 3-pointer at the 3:55 mark.

David Loubeau hit a bucket for the Aggies that Sam Grooms answered for the Sooners. Then Middleton's 3-pointer gave A&M a 55-47 lead with 1:42 left.

Loubeau and Middleton each had 15 points for the Aggies (14-17), playing their last Big 12 tournament before joining the Southeastern Conference. In Thursday's quarterfinals, they will meet No. 3 Kansas, which beat them twice while rolling to its eighth straight regular-season Big 12 championship.

Oklahoma (15-16) got 17 points from Osby and 13 from Grooms.
