An overtime goal by senior midfielder Mikayla Griggs led the Heritage varsity girls soccer team to a 2-1 victory over Berkeley in the first round of the North Coast Section playoffs on Wednesday night.

After the Patriots at this stage last year, this was the first playoff win for sixth-seeded Heritage in its brief varsity history.

The goal was Griggs’ second of the game, the first coming shortly before the final whistle of regulation. Both were assisted by sophomore forward Jamie Barron.

“Mikayla was determined not to lose,” Patriots head coach Randy James said. “She wanted to win and that’s the best way to put it.”

Berkeley led 1-0 at halftime on the strength of a goal by freshman Farah Otero-Amad.

Heritage will face No. 3 seed Castro Valley, from the Hayward Area Athletic League, at home on Saturday.

“We haven’t played Castro Valley this year, so we’re focused on getting ourselves focused the best we can,” James said. “We expect a very big challenge for the girls and I think we’re up for it.”
