The UCSD men’s basketball team suffered its first loss of the season, falling to Division I cross-town rival University of San Diego Tuesday night at the Toreros’ Jenny Craig Pavilion.

Kyle Moyneur led the Tritons with 16 points — shooting 67 percent from the field — and four rebounds, and freshman Hassan Bassiri picked up eight points and four assists. Bassari picked up significant playing time in place of regular point guard Cameron Jackson, who did not play.

Visiting UCSD put up a valiant effort, but in the end, was simply outsized and outmuscled by the USD Toreros. The Tritons were within four points with eight minutes to go in the first half, but a 20-4 run put USD out of range.

During that dreadful eight-minute stretch of the first half, UCSD went 1-8 from the field and did not pick up a rebound, while the Toreros went 8-13 and grabbed 11 boards.

The Tritons struggled inside, finishing the game with 28 rebounds compared to USD’s 48. Torero center Kevin Hanson dominated the key all night, picking up game-highs in rebounds with 11 as well as blocks with three. Andre Laws led USD with 26 points and four assists.

The Toreros’ zone defense stifled UCSD’s offense, forcing the Tritons to keep the ball on the perimeter most of the game. Of UCSD’s 52 shots, 30 of them were from beyond the three-point line.

The Tritons next play SDSU on Tuesday night at Cox Arena at 7 p.m.
