The Hawaii men’s basketball team suffered its first loss under coach Gib Arnold in a 54-53 defeat at Cal Poly via a tip-in at the buzzer.

UH lost its 12th straight road game going back to the 2008-09 season.

Hawaii’s Joston Thomas put in a go-ahead basket with 22.2 seconds left, but the Mustangs called timeout and scored on their third attempt in the final 10 seconds of play.

Chris O’Brien had the game-winning tip-in with no time remaining.

The Rainbow Warriors (5-1) shot 51.4 percent from the field to Poly’s 33.3 percent, but UH was undone by 27 turnovers.

Zane Johnson led UH with 11 points, while Thomas had 10.

The tightly played contest was a return game from last season’s BracketBusters game in Honolulu, won 102-89 by the Mustangs.

The Rainbows committed 17 turnovers in the first half and trailed by 10 points early, but rallied behind the scoring of Johnson and Trevor Wiseman (eight points). Wiseman made the first start of his UH career, filling in for injured forward Bill Amis.

Shawn Lewis had a game-high 15 points for the Mustangs (3-3).

UH continues its two-game road trip against No. 21 BYU on Saturday at EnergySolutions Arena in Salt Lake City.
