Harvard-Westlake duo of Drew Bowser, Pete Crow-Armstrong make impact

Harvard-Westlake is expected to score lots of runs in baseball this season, and the Wolverines’ 11-3 season-opening, six-inning win over Mira Costa on Thursday was a reminder how productive they might be.

Leadoff hitter Pete Crow-Armstrong contributed two doubles and No. 3 hitter Drew Bowser hit a three-run home run to help the Wolverines come back from a 3-1 deficit. Mira Costa received a two-run home run from Nick Bacura and a solo home run from Dylan Knowles. But Harvard-Westlake’s firepower was just starting, and Mira Costa didn’t help matters by committing five errors.
