LARAMIE, Wyo. - Marc Jackson scored 21 points to lead Utah to a 69-56 win over Wyoming on Monday, handing Rick Majerus his 400th coaching victory.

Tim Frost added 16 points and Nick Jacobson 15 for the Utes, who picked up their first win in Laramie since Jan. 28, 1993, snapping a seven-game skid at the Arena-Auditorium.

Donta Richardson led Wyoming with 23 points. Uche Nsonwu-Amadi had eight points and 13 rebounds for the Cowboys.

Majerus is 400-138 in his 19th season as head coach, including stops at Marquette and Ball State. In 14 years at Utah, Majerus is 301-86.

Utah (18-4, 6-1 Mountain West) won its sixth straight and 13th of its last 14 to stay in a tie for first place. Wyoming (16-6, 4-3) lost three straight conference games for the first time in six seasons.

The Utes shot 46 percent, including 8-of-14 from the arc, while the Cowboys shot 37.5 percent, lowest since a 74-60 win over Detroit on Dec. 28.

Utah held Wyoming to one field goal during an eight-minute stretch of the second half to put the game away.

After Jay Straight's 3-pointer for Wyoming tied the game at 35 with 16:02 remaining, Utah went on a 13-3 run.

Trace Caton had a putback and 3-pointer and a layup by Jackson capped the surge, which left the Utes up 48-38 with 8:18 to play.

The lead reached 55-44 on Jacobson's running jumper at the 4:49 mark and then 67-53 on two free throws by Frost with 48 seconds remaining.

Over the last 9 minutes, Wyoming could draw no closer than seven points. The Cowboys had not lost back-to-back conference home games since 1994-95.

Jackson scored 10 of his points in the first half to stake Utah to a 30-26 lead at intermission.

Wyoming took its last lead at 16-14 after a 20-foot jumper by Joe Ries with 7:28 remaining in the first period, but Jackson scored the next eight points on a pair of 3-pointers and a layup to put the Utes up 22-16.
