Muir turned a four-point game at the half into a second-half rout as the Mustangs dominated Crescenta Valley 70-56 on Tuesday night to remain undefeated in the Pacific League. Muir (17-1, 6-0) got solid contributions from Jelani Mitchell (20 points) and Andre Frazier (16 points). But one of the big contributors off the bench was sophomore Brian Carreir, who finished with 12 points. Pasadena (13-5, 6-0) defeated Glendale 82-44 to remain undefeated in the Pacific League, setting up Friday’s showdown at Pasadena. The game is scheduled for a 5 p.m. start, but trust me when I say that you want to get there super early if you want a seat. Read the Star-News on Wednsday for a complete story on Muir’s game. I’ll have more on Friday’s game later this week.
