Boulder, Colo. ? Walking toward the winning locker room, a veteran teammate draped his arm over Richard Roby’s head and yelled, “That’s what I’m talking about!”

Everyone at Colorado knew it was just a matter of time before Roby did something big. It happened Wednesday night, when the freshman guard hit a three-pointer with 21 seconds left to lift the Buffaloes to a 64-62 victory over Missouri.

“I saw my defender’s hands were down and seized the opportunity, and I shot it,” Roby said. “Thank God it went in.”

Roby, the half-brother of Denver Nuggets forward Kenyon Martin, dribbled a couple of times, took a step inside the three-point line to create room between himself and the defender, then stepped behind the line and swished the game-winner.

It gave Colorado (10-7 overall, 2-4 Big 12 Conference) a modest two-game winning streak and a much-needed shot of momentum after a losing four straight to start the conference season.

Missouri fell to 0-6 away from home this season.

“I think we’re closer,” Missouri coach Quin Snyder said. “We were in position to win a game on the road, but we didn’t finish it. It’s the same formula as at home, but it’s harder.”
