AIR FORCE ACADEMY, Colo. (AP) _ Alex Jensen made a 3-point basket and a three-point play in the final 38 seconds, rallying No. 19 Utah to a 64-63 victory over stubborn Air Force on Saturday night.

The Utes (16-3, 5-0 Mountain West) built an 11-point lead midway through the second half and then saw Air Force erase it with a 15-4 run.

Jarvis Croff's 3-pointer from the corner and Tom Bellairs' free throw gave the Falcons (6-11, 2-3) a 62-58 lead with 49 seconds left, but Jensen promptly made a long 3-pointer.

After Tyron Wright sank 1-of-2 free throws for a 63-61 lead, Jensen made a driving layup and was fouled with 16.9 seconds left, making the free throw as well.

Air Force nearly lost the ball twice on its last possession, and freshman Vernard Jenkins missed a shot from the line as time expired.

Jensen finished with 20 points and nine rebounds. Tony Harvey added 12 points and Hanno Mottola, who played only 24 minutes because of foul trouble and a hyperextended left elbow, had 10 points.

Wright scored 20 points for the Falcons and Croff had 19.

Utah shot 73 percent (16-of-22) in the second half and 52 percent for the game, compared to Air Force's 41 percent. The Falcons were 21-of-25 from the line to the Utes' 5-of-11.

Mottola, scoreless in the first half, fueled a 9-0 run early in the second half with six points as Utah took control. Mottola fell on his elbow on a drive to the basket and missed the next three minutes, but he returned with an elastic sleeve on his elbow and made two jumpers.

Wright had 10 of the Falcons' 15 points during their furious comeback, and Croff hit two 3-pointers down the stretch.

With Mottola playing only nine minutes of the first half because of foul trouble, Air Force fashioned an 8-0 run to take a 23-18 lead with 3:18 left.

Jensen, however, scored the next seven points of the game on a layup, a 3-pointer and another layup for a 25-23 lead with 21 seconds left in the half.

Bellairs sank two free throws to produce a 25-25 halftime tie.
