DANVILLE -- It's been seven years since the Monte Vista boys soccer team advanced past the quarterfinals of the North Coast Section Division I playoffs, which for the Mustangs, felt like a lifetime.

The 2007 season, one in which the Mustangs won the NCS Division I title, was the last time Monte Vista had moved past the quarterfinal round until Saturday's 2-1 afternoon win over visiting Richmond.

Monte Vista, the No. 2 seed, will host the winner of Saturday night's game between No. 3 Pittsburg and No. 6 Amador Valley on Wednesday.

"The season can be a grind this time of year and it's tough to stay fresh and focused," Monte Vista coach Matt Zahner said. "But it feels really, really good to get through."

Monte Vista (19-3-2) took the lead twice, making it stand up the second time as a John Austin goal in the 30th minute proved to be the difference.

Charles Zaloumis set up both goals, including the 4th minute header by Jeff Greenberg that gave the Mustangs an early 1-0 lead.

The seventh-seeded Oilers (15-7-3) got level in the 24th minute thanks to Harold Erroa, after a great ball by Addison Escobar set him up 1-on-1 with the keeper.

Richmond stayed close and had a chance to equalize late in the game thanks to the play of keeper Humberto Melendez, who had seven saves, two of them in 1-on-1 situations.
