FAYETTEVILLE, ARK. ? Marcus Watkins’ three-pointer rolled in and out in the final seconds, and Arkansas held on for a 66-63 victory over Missouri on Friday night.

The Razorbacks (5-2) blew a 14-point second-half lead, but went ahead 63-61 on Jonathon Modica’s three-point play with 1:11 remaining. Arkansas then missed three free throws down the stretch, allowing Missouri one final possession trailing by three.

The Razorbacks didn’t want to allow a three-pointer to tie it, so Eric Ferguson fouled Jason Horton deliberately with 5.8 seconds remaining. Horton missed the front end of a one-and-one, and Missouri rebounded, but Watkins’ open shot from the right wing didn’t stay down.

Ronnie Brewer scored 20 points for Arkansas, including a breakaway dunk that put the Razorbacks ahead 53-39 with just over eight minutes remaining. But Missouri (2-2) went on a 16-2 run to tie it.

Horton gave Missouri a 58-57 lead with a three-pointer, and Brewer answered with a three-pointer of his own. Horton then banked in a three-pointer to put the Tigers ahead 61-60, but Modica’s basket and free throw put Arkansas ahead to stay.

Kevin Young had 13 points and eight rebounds for Missouri.

Horton scored nine points, all on second-half three-pointers.

Missouri's Jason Horton, right, drives around Arkansas' Dontell Jefferon in the second half of Missouri's 63-66 loss to Arkansas. Horton scored nine points Friday in Fayetteville, Ark.

The Tigers shot 9-of-18 from three-point range, 6-of-9 in the second half.

Both teams struggled from the free-throw line. Missouri went 8-of-17, and Arkansas shot 15-of-23.

The Razorbacks led 34-26 after a spirited but sloppy first half in which the teams combined for 19 turnovers.

The Razorbacks’ bench was charged with an early technical after coach Stan Heath argued a non-call on Modica’s drive. The sequence appeared to spark Arkansas, which went on a 25-8 run to take a 31-16 lead.
