BOULDER, Colo. (AP) D'Shawn Schwartz scored 13 of his 15 points in the second half Saturday night when No. 25 Colorado turned its defensive pressure into overdrive to overwhelm scrappy San Diego 71-53 after leading by just three at halftime.

That sizzling second-half shutdown is just what coach Tad Boyle wants to see from his Buffs (2-0) Monday night when they host UC-Irvine, which returns three starters from a 31-win team that upset Kansas State in the NCAA tournament.

"This is somebody we cannot take lightly," said Boyle, who improved to 10-0 in home openers. "They're deep, they're big, they're physical. We'd better play better. We need the second-half Colorado team tonight, not the first-half. And we've got to put two halves together because Irvine, much like San Diego, is not going beat themselves."
