Lucas Siewert and McKinley Wright IV led the Colorado Buffaloes to a 67-60 win over Arizona on Sunday night, sending the Wildcats to their first seven-game losing streak in 36 years.

Siewert had 15 points and nine rebounds and Wright had 14 points in the Buffaloes' fifth consecutive Pac-12 win.

The Buffs (16-9, 7-6) had never won more than three consecutive league games since bolting the Big 12 in 2011.

Ryan Luther scored 17 points for the Wildcats (14-12, 5-8) and Dylan Smith had 16.

Playing without injured guard Brandon Williams for a fifth straight game, the Wildcats never led.

They trailed by as many as 11 points in the first half but cut their deficit to 34-28 at the break and came out in the second half determined to get center Chase Jeter more involved after he was held to one bucket in the first half.

Jeter, who finished with 10 points scored Arizona's first three baskets after the break, on a reverse layup, a dunk and a hook, then fed Luther driving to the basket to cap a 15-4 run that tied it at 36.

Wright scored the game's next seven points, sparking a 17-5 run that put Colorado ahead 53-41 halfway through the second half.

The Wildcats never got closer than seven points after that.
