The San Marcos girls water polo dynasty put another feather in its cap on Wednesday, capturing its fifth straight Channel League title with an 18-6 rout of rival Dos Pueblos at Elings Aquatic Center. “It’s a great group,” San Marcos head coach Chuckie Roth said. Roth led his team to league titles in six of the last seven seasons and 10 championships since 2014. “They’re just great kids, and they really want to be great, and they work really hard, and they deserve this. Dos Pueblos’ Talia Marshall opened the scoring, while Raisin responded with two unanswered goals to take a 9-2 lead into halftime.
