LA JOLLA, Calif. -- Behind the strong play of its three seniors, top-seeded UC San Diego defeated No. 4 seed Western Washington 81-66 in the second round of the NCAA tournament on Saturday.

The senior trio of Chelsea Carlisle, Daisy Feder and Lauren Freidenberg combined to score 53 points for the Tritons, who jumped all over the Vikings in the opening half and cruised home from there. UCSD shot 45 percent in the period and built a commanding 25-point lead to easily punch its ticket to Monday's West Regional Championship game.

The Tritons, who are now 30-2 on the season, will take on second-seeded Alaska Anchorage for the regional title on Monday. The Seawolves (29-4) defeated No. 3 seed Grand Canyon 77-58 on Saturday.

"I thought the way that we came out in the first half was some of the best basketball we've played all year, and I was very pleased with the energy and focus," head coach Charity Elliott said. "Our kids just did a great job. We beat a very good Western Washington team tonight and I'm proud of how we were able to get them on their heels early on."
