LA JOLLA, Calif. - The 2011 Triton Invitational got underway Friday with multiple sections of women's hammer throw and discus and the open sections in the pole vault. UC San Diego had several student-athletes competing on the opening day of competition at the Triton Track and Field Stadium.

Senior Justin Rovin had the biggest highlight of the day for the Tritons, as the Laguna Beach native finished fourth in the pole vault after clearing 15'2.25". His performance went down as a personal best in the event and fell six inches shy of the second place mark cleared by both Tyler Wallace of Long Beach State and TJ Harris of Paradise Valley Community College. PVCC's Eric Frawley had the top mark at 16'2".

Freshman Clint Rosser finished seventh in the vault with a leap of 14'8.25", while fellow rookie Benjamin Berthet cleared 13'8.5" to claim a share of 16th place.

On the women's side, UCSD had three athletes competing against an elite field in the open section of the discus. Senior Danielle Thu finished 15th (138'3"), while sophomore Uchenna Agbahiwe took 16th (134'1") and Eva Isaacs placed 27th (107'1").

Thu didn't have her best day in the women's hammer throw invitational, finishing 19th in her specialty with a mark of 167'4". Shana Emile was 36th in the same event (146'3"), which was two spots in front of Karla Spence (139'8").

Other meet highlights included Jessica Cosby's performance in the hammer throw and Suzy Powell's effort in the discus. Cosby, a 2008 U.S. Olympian, beat out 2008 Canadian Olympian Sultana Frizell with a toss of 228'1" to win, while Powell uncorked a throw of 199'5" to best a field that featured Arizona State's Anna Jelmini and 2008 Olympic gold medalist Stephanie Trafton.
