Denmon and Ricardo Ratliffe had 19 points apiece for Missouri, which has lost seven straight to Texas A&M.

It was the first overtime game for the Aggies at home since they lost 116-110 in five OTs against Baylor in 2008.

Nathan Walkup added 16 points for Texas A&M and David Loubeau had 12 points.

Bowers had a chance to give Missouri a three-point lead with 27 seconds left in regulation, but he went 1 for 2 from the line and Middleton tied it with his foul shots. The Tigers led by four before Dash Harris converted a three-point play for Texas A&M with just under a minute remaining.

Texas A&M used a 10-4 surge to take a 59-51 lead with 14 minutes to play. Naji Hibbert capped the spurt with a 3-pointer.
