LOS ANGELES – The Galen Center’s inaugural season could not have had a better ending. Senior Lodrick Stewart led the USC student section in displaying the university’s trademark victory sign as the school’s fight song played. This for a team that entered the season picked to finish sixth in the conference and starting freshmen at point guard and power forward. “We’re playing for seeding now,” Stewart said. “There’s not a doubt we’re going to the tournament. I think we’re going now, and the coaches feel the same way.” USC’s 15-3 record at Galen Center is its best home mark since going 16-3 in 1961. The Trojans’ three seniors – Stewart, Penrose and center Abdoulaye N’diaye – received framed jerseys before their final home game. N’diaye, making a rare start, came out and scored USC’s first four points. Stewart drained four 3-pointers to give him 220 for his career, breaking the all-time USC mark of 218 held by Brandon Granville (1999-2002). “It’s great to get the record on a day like this,” said Stewart, who came out to a large ovation with 55.8 seconds remaining. “It was so sad knowing it’s my last time playing here.” Stewart finished with 13 points, seven rebounds and two blocked shots. Taj Gibson led the Trojans with 18 points. 160Want local news?Sign up for the Localist and stay informed Something went wrong. Please try again.subscribeCongratulations! You’re all set! Then the players lifted senior walk-on Chris Penrose – who hit a 3-pointer in the final seconds – onto their shoulders and carried him off the court. USC’s 84-66 victory over California in its final home game displayed everything that has changed this year within the program – the attitude, the attendance and the atmosphere. “We said from day one, we’re not going to beg our people to come out,” said coach Tim Floyd after his team played in front of a sellout Galen Center-record crowd of 10,027. “You have to earn those things.” USC has done that with a team that has defied all expectations. The Trojans (21-8, 11-5) are guaranteed at least fourth place in the conference, will take second if they win both games in Washington this week and can wrap up third with any win or Stanford loss in the final two games. Teammates surrounded Stewart, some going into the aisles, as the crowd paid tribute to one of the Trojans’ best seasons since the Pacific-10 Conference expanded to 10 teams in 1979. The players paid tribute back for the electric atmosphere that built all season and reached a crescendo Saturday.
