Crosstown Los Angeles rivals meet as Big Ten Conference foes for the first time on Monday when UCLA visits Southern California.Since pulling out of a four-game tailspin, UCLA (14-6, 5-4 Big Ten) has come alive with a three-game winning streak. The Bruins followed an 85-83 home win over No. 18 Wisconsin on Tuesday with a 65-60 defeat of Washington in Seattle on Saturday.Big man Aday Mara had his second standout performance coming off the bench, following up a career high of 22 points vs. Wisconsin with 12 points and seven rebounds at Washington.”What he’s doing in these last couple games is what he does every day in practice,” teammate Dylan Andrews said. “Aday is a monster, and I’m glad people are starting to see that.”Andrews has also seen an uptick in his play. UCLA coach Mick Cronin called out Andrews, the team’s leading scorer a season ago, and Andrews has responded with games of 13 points vs. Iowa; 10 points and seven assists vs. Wisconsin; and nine points, including a pivotal, late-game 3-pointer at Washington.Andrews is part of a Bruins backcourt that includes veteran Kobe Johnson, who played for USC the last three seasons. Johnson returns to the Galen Center for the first since his transfer, but the Trojans team he sees looks much different than the lineup he was in.In its first season under coach Eric Musselman, USC (12-7, 4-4) underwent dramatic roster changes. Leading the new group is guard Desmond Claude, the Trojans’ leading scorer at 16.3 points per game.
