LARAMIE — Leonard Washington's breakout game put an end to two years of frustration for Wyoming in the rivalry with Colorado State known as the Border War.
The transfer from USC posted career highs of 32 points and 14 rebounds to lead Wyoming to a 70-51 victory Saturday, snapping the Rams' eight-game win streak and giving the Cowboys their first victory in the series since 2009.
Luke Martinez added 12 for the Cowboys (16-3, 2-1 Mountain West), who never trailed in Saturday's game.
Colorado State (13-5, 2-1) was led by Greg Smith's 18 points, while Jesse Carr scored 12 and Pierce Hornung added 10 points and seven rebounds.
The Cowboys held the Rams' top two scorers, Wes Eikmeier and Dorian Green, to a total of seven points. The duo was averaging over 30 points combined.
After the Cowboys' postgame news conference, Wyoming guard JayDee Luster looked at the stat sheet and noticed that Washington was also 3 of 4 from 3-point range.
"Is there anything you didn't do tonight?" Luster asked.
It was that kind of night for Washington, a 6-foot-7 junior who sat out last season under the NCAA's transfer rule. His game-best marks at USC were 17 points and 12 rebounds; and with Wyoming, the previous highs were 18 points and 10 boards.
"I take my hat off to my teammates for getting me the ball," he said. He was 12 of 16 from the floor, and five of his 14 rebounds were on the offensive glass, which turned into 10 points for the Cowboys. "I motivated myself today to come out and get as many rebounds as I could."
Wyoming coach Larry Shyatt credited his team for grabbing the majority of loose balls, especially Washington.
"He did a great job of getting second and third efforts," Shyatt said. "They (the Rams) met him a couple times at the glass and then he went back up. I thought that was the difference tonight for him."
Washington banked in a 3-pointer as the shot clock expired to give Wyoming a 64-49 lead with 2:56 to play, then repeated the trick, minus the backboard, with 42 seconds left to make it 70-49.
"He can take you off the drive, he's got really good hands ... comes up with steals, tips, deflects . scores inside," Colorado State coach Tim Miles said. "He's just a really great player."
Colorado State entered as the nation's fourth-best 3-point shooting team at 44 percent, but connected on just 29 percent from behind the arc on Saturday.
Wyoming won the rebound battle 35-24, including a 13-4 edge on the offensive end.
"The main thing that killed us was offensive rebounding," Carr said. "They went after it. We haven't seen something like that in the last couple years."
Wyoming opened a 39-22 lead early in the second half on a 3-pointer by Francisco Cruz. CSU cut the deficit to single digits after Green sank two foul shots with 11:06 to play — his first points of the contest — to draw the Rams within 47-38.
Washington answered by tipping in his own miss, then he stole the ball on the Rams' next possession, which led to a pair of free throws by Luster that put Wyoming up by 13. After two free throws by Hornung again drew CSU within nine with 5:29 to play, Wyoming closed the game on a 12-2 run.
