The Bishop’s School girls water polo team proved the old adage that defense wins championships. The Lady Knights got back to their winning ways, allowing their four opponents in last weekend’s Tyr Cup a total of eight goals to their 52 goals en route to the title. Bishop’s (9-3) scored wins over Beckman High School (17-1, senior Sammi Peck four goals); El Dorado (14-2, senior Sarah Presant four goals, freshman Jessica Webster four); Santa Barbara (14-2, senior Kirsten Siegel six goals); and Fountain Valley (7-3, Peck two goals, junior Kristen Casey two). Presant was named tourney MVP, with sophomore Gabby Stone being named the most outstanding goalie. Peck, Melanie Boehrig and Siegel were named to the all-tournament team. Elsewhere, La Jolla (5-1) topped La Costa Canyon 17-5 Jan. 16 as Ariel Arcidiacono led the way with four goals. Kate Woods and Bridgette Souza each had three, while Victoria Frager had two and Meagan Moreland, Christina Kirby, Aoife Collins, Darby Broekema and Jordan Atnip each had one. La Jolla plays in the America’s Finest City tourney Jan. 22-23.
