SAN DIEGO (Ticker) -- Their schools might have changed, but Bobby Knight got the better of Steve Fisher again.
Kasib Powell scored 22 points and Nick Valdez added a season-high 21 off the bench to lead 21st-ranked Texas Tech to a 75-63 victory over San Diego State in a matchup of former Big Ten Conference coaches.
While at Indiana, Knight went 10-6 against Fisher's Michigan Wolverines. Since moving to Texas Tech, the volatile coach is 2-0 to extend his winning streak vs. Fisher to four games.
"I like that team and how hard they play," Knight said. "I was impressed with a lot of the things they did defensively. Steve has done a good job with them, particularly at the defensive end."
The Red Raiders (10-1) won their fifth straight game since enduring their lone loss, a 67-62 setback at Wyoming on December 14.
"When I looked at our schedule, I wanted to end the non-conference part of it with a game that would test us," Knight said. "That's what we got tonight ... a good test."
Tony Bland scored 13 points for San Diego (8-4), which had its six-game winning streak stopped. The Aztecs also had their four-game home winning streak come to an end.
"Obviously, I'm extremely disappointed in the loss, whether it's Texas Tech or any other team," Bland said. "Especially in front of a national audience (on ESPN). But it's not the coaches' fault or anybody else's. It's our fault. We didn't take care of business."
Valdez, who started two times this season, entered 1:19 into the first half and played the rest of the game. Valdez scored 13 points in the first half, leading Texas Tech to a 42-38 lead.
Both teams got of to a hot shooting start. The Red Raiders hit on 54 percent (15-of-28) from the field, while the Aztecs shot 56 percent (16-of-29).
But San Diego State did not score its first basket of the second half until Bland scored with 13:59 left and by that time the Aztecs trailed, 52-40.
"We played as well defensively in the second half as we have all year," Knight said. "I commented to the team during a timeout that their defense was scoring the baskets for us."
Andre Emmett contributed 16 points and eight rebounds and Valdez pulled down nine boards for the Red Raiders, who shot 47.5 percent (29-of-61) and converted 16-of-19 from the free throw line.
Mike Mackell chipped in 11 points and Deandre Moore had eight as the Aztecs shot 45 percent (27-of-60), including 7-of-22 (32 percent) from 3-point range. They also committed a season-high 24 turnovers and were outrebounded, 36-31.
