The last 10 minutes of the contest never saw more than a four-point difference. With 4:45 remaining, Negus Webster-Chan's putback and Roderick Bobbitt's layup kept the Rainbow Warriors (16-8, 4-4 Big West) in front. Reese Morgan kept answering, converting four at the line to keep the Mustangs within one.
Bobbitt made another layup for a three-point lead with 1:10 to play, but a turnover put the ball back in Mustangs possession with 21 seconds left on the clock. Cal Poly's Joel Awich split a pair of free throws, and Bobbitt did the same on the other end for the final margin.
Morgan scored 16 points and Ridge Shipley added 12 for the Mustangs (10-11, 3-6).
