CAMBRIDGE, Mass. -- Hawaii began its quest at the 2013 NCAA championships with a 13-6 quarterfinal win against UC San Diego on Friday in Blodgett Pool at Harvard.

UH (22-9) won its ninth consecutive contest and improved to a perfect 4-0 all-time in NCAA quarterfinal matches.

The Rainbow Wahine advanced to Saturday's semifinals where they will face top-seeded USC. The Trojans defeated Pomona-Pitzer 26-1 in their quarterfinal matchup.

Hawaii was sharp on both ends of the pool. The No. 4-seed Rainbow Wahine got a balanced attack with six different players getting in the scoring column, including four players with multiple goals.

Leading the way for Hawaii was sophomore attacker Caity Lopes da Silva with a career-high four goals.

Meanwhile, the UH defense continued to its stellar play holding the fifth-seeded Tritons (25-14) to just three goals before surrendering three goals late in the game with the outcome already in hand.

Goalkeeper Amy Carlson set the tone early by stuffing a UCSD penalty shot in the first quarter as the Tritons continued to have difficulty finding the back of the net.

UH's Zoe Respondek scored the first two goals of the match though UH held just a 2-1 lead after the first frame. However, it was all Rainbow Wahine after that.

UH outscored the Tritons 10-2 through the next two quarter to lead 7-2 at the break and 12-3 after three quarters.
