LAS VEGAS — Chris Miles took just three shots in a span of a few minutes, but they loomed huge in BYU's win over San Diego State and berth in tonight's championship game of the Mountain West Conference tournament.

Working against SDSU center Ryan Amoroso, Miles knocked down all three of his field goals inside the paint to ignite a stagnant Cougar offense to a 8-2 second-half run and take control the semifinal game which BYU prevailed 63-54.

"They were huge shots, just huge," said senior captain Sam Burgess. "They came just at the right time."

Miles finished with six points and one board in nine minutes. But he was perfect as a shooter.

"He works hard on those moves every day in practice," said Trent Plaisted. "He came in and gave us a lot of energy. He gave us a huge lift. Offensively, he had some great post moves. He is a relentless worker. You've got to give him a lot of credit because that stuff is paying off in games."

Said Miles: "I just tried to come in and help, give our team a lift."

"I think if you look at all our games, we've had a guy come off the bench and really contribute," said BYUcoach Dave Rose. "Chris Miles did that tonight in the second half. Chris Collinsworth gave us that lift in the first."

Plaisted, who had 19 points, experienced more success than he's used to against the Aztecs.

"I think for the most part, I didn't do a good job of keeping him away from the hoop," said Amoroso.
