West Haven junior pitcher Eric Stone had successful surgery Wednesday to repair a torn meniscus in his left leg.

Westies coach Mike Anquillare said there is no time table for his return and will be re-evaluated next week. He also begins rehab next week.

“It’s a big blow,” Anquillare said. “He’s a good pitcher. He was going to be our ace. But we have to regroup and others have to step up. If he comes back, it’s a bonus.”

Stone tore his meniscus in a preseason game against Career, when he attempted to pick off a runner at first base.

Though inexperienced (he only threw 23 innings last season), Stone was expected to emerge as a top pitcher for West Haven. Along with seniors

John Ascenzia and Matt Langello, senior Ray Novak and junior Jeremy Soule will now see more time on the mound with Stone out. The Westies opened their season with a 17-9 loss Wednesday to North Haven.
