Fifth-seeded Mira Costa dominated host Westlake Thursday, but came up short in its quarterfinal game of the CIF Southern Section Division 2 Championships.
Despite controlling the first half, the Bay League champion Mustangs failed to convert on their opportunities and fourth-seeded Westlake made the most of its chances, scoring the game’s lone goal in the 44th minute.
Mira Costa goalkeeper Nonie Frishette made three saves, but the one shot that got away was the difference maker in the game.
Coach Patty Perkinson’s Mustangs had their best playoff run in seven seasons and finished with an impressive 17-3-4 record.
