Visiting Corona del Mar, ranked No. 7 in Orange County, scored with three minutes left Thursday, breaking a 5-5 tie and defeating LA No. 13 San Marcos 7-5.
The Royals (10-2) lost for the first time since a season-opening loss to LA No. 8 Oaks Christian.
Mason Zimmerman scored four goals to lead the San Marcos offense, and goalkeeper Ryan Lehman stopped a number of CdM shots to keep the Royals in the game.
The teams were even at 5-5 entering the fourth quarter, but the Sea Kings squeezed in the go-ahead goal with three minutes to play. With the Royals extending their defense in pursuit of a take-away and a chance ti pull even again, CdM capitalized with an insurance goal for the final margin.
Coach Rick Lehman said his squad was proud of its performance against a program considered one of the best in Southern California. San Marcos is in only its fifth season of CIF-level lacrosse.
San Marcos faces Channel League rival Dos Pueblos on Friday for the Royals’ senior night. A San Marcos victory will clinch the league title outright.
