LOS ANGELES – Southern California’s defensive style is man-to-man. The Trojans don’t pressure full-court, and yet that’s what earned them the school’s first Pac-10 tournament championship.

Daniel Hackett hit the tying and go-ahead free throws with 42 seconds remaining and USC held on for a 66-63 victory over No. 23 Arizona State yesterday.

Freshman DeMar DeRozan scored 25 points, Hackett added 19 and Dwight Lewis 13 for the sixth-seeded Trojans (21-12), who overcame a 15-point halftime deficit and became the lowest seed to win the tourney.

James Harden, the Pac-10 player of the year, missed a free throw, a layup and a 3-pointer in the final 50 seconds for the fourth-seeded Sun Devils (24-9). They were led by Jeff Pendergraph with 20 points and Derek Glasser with 16 in the school’s first appearance in the title game.

A stunned Pendergraph couldn’t describe his emotions afterward.

“It’s a lot of stuff,” he said, “and I don’t want to say something crazy.”

The Trojans had been 0-3 in league tourney finals, losing to Oregon in 2003 and 2007 and to Arizona in 2002. The previous lowest-seeded team to win was Oregon six years ago.

“We focused on our practice and preparation and we took it one game at a time,” Hackett said. “It got us to a championship.”

DeRozan was named the tournament’s most outstanding player.

“He played like a man, not a freshman,” Hackett said. “He came in with a goal in mind, to make something at this school.”
