TUCSON, Ariz. (AP) _ Chris Rodgers knows his role for Arizona. He's no starter, he's the energizer.
Rodgers filled that role and more, scoring a career-high 22 points, seven during a decisive second-half surge, and the 17th-ranked Wildcats kept Southern California winless in the Pac-10 with a 77-68 victory Thursday night.
Salim Stoudamire had 21 points on 5-of-9 shooting from 3-point range for the Wildcats (13-3, 3-1 Pac-10), who rebounded from a 87-76 loss at California. Hassan Adams added 15 points, and Channing Frye had 12.
``I don't try to focus on scoring points,'' Rodgers said. ``I just want to give my energy, and show some passion for the game, and whatever happens scoring, just happens.''
With playmaker Mustafa Shakur ineffective, Rodgers played 33 minutes, sinking eight of 15 shots with a team-high four assists.
Rodgers was on the court when the game ended.
Olson said he talked to Stoudamire on Wednesday and told him not to be quite so unselfish.
``I want you to shoot the ball,'' Olson said he told the senior. ``You're the best shooter in the country.''
Olson pointed to an NBA-range 3-pointer that Stoudamire hit.
``You saw the one that was about 8 feet outside the 3-point line,'' Olson said. ``That shot's fine with me because he drains that in a practice situation, too.''
Nick Young led USC (0-5, 7-9) with 18 points. Gabe Pruitt added 12, and Jeff McMillan had 11.
``I'm not into moral victories, but I was glad to see this team never stopped competing,'' interim coach Jim Saia said. ``But we just didn't stay poised enough to win in this type of environment.''
The Trojans found out earlier in the day that they had a coach for next season. Tim Floyd is to be introduced at a news conference in Los Angeles on Friday.
Henry Bibby was fired Dec. 6, four games into the season, and replaced by Saia on an interim basis. Rick Majerus took the job for five days, then changed his mind and resigned for health reasons.
Arizona led most of the game but never by more than 12 points.
``We just don't have that killer instinct,'' Olson said.
The Wildcats went nearly 5 minutes without a point early in the second half, while USC scored six to cut the lead to 52-49 after Rory O'Neil's inside basket with 11:49 to go. Rodgers ended the drought with a layup, then Stoudemire slammed one home one-handed on a fast break and sank a 3-pointer in a 7-0 Arizona spurt that boosted the lead to 59-49 with 9:01 left.
USC cut it to 64-60 on consecutive inside baskets, the second one a stuff, by McMillan. Arizona responded with an 8-0 run, the last seven by Rodgers, to take its biggest lead of the night, 72-60, with 3:25 remaining.
The Trojans took a 33-31 lead on Pruitt's four-point play with 3:24 to go. Pruitt sank the 3-pointer and was fouled by Frye, then made the free throw.
Rodgers' 3-pointer put Arizona back up for good, 34-33, and he made another with 38 seconds to go to put the Wildcats ahead 42-38 at the half.
Arizona made it a 9-0 run by scoring the first six points of the second half, taking a 48-38 on Adams' baseline jumper with 18:09 remaining.
Sophomore Kirk Walter entered the game in the first half, his first appearance of the season. Olson had intended to sit Walter out as a redshirt this season.
Olson said the staff decided to play Walter because he has been the second-most consistent big man in practice, behind Frye.
USC shot 57 percent in the first half, compared with 44 percent for Arizona. The Wildcats, though, were 6-for-13 on 3-pointers in the first 20 minutes, including 4-for-6 by Stoudamire.
Young scored 14 in the first half on 7-for-10 shooting.
