LAFAYETTE -- A lot was at stake at Acalanes High on Saturday -- the No. 1 spot in the Bay Area News Group East Bay boys soccer rankings and quite possibly the top seed in the North Coast Section Division II playoffs.

The top-ranked Dons used an equalizer before halftime to draw even with No. 3 Ygnacio Valley 1-1 in a nonleague match.

"Acalanes came to play and it made it a great game," Ygnacio Valley coach Cesar Chavez said. "It was an NCS quality game, which made it very exciting."

Acalanes (13-0-2) remained unbeaten and is now 1-0-1 against Ygnacio Valley (10-1-3) this season, giving the home team an edge in both the rankings and the playoff seeding.

In a very even game, there was fantastic play from Jose Aguilar, Mario Mendez and Edgar Damian for the Warriors as well from Graham Lindgren, Luc Van Oss and Eric Rogstad for the Dons.

"It was a fair result and an even game again," Acalanes coach Paul Curtis said. "It was two very good teams working very hard."

The keeper Rogstad was called into action multiple times to keep a dangerous Ygnacio Valley attack at bay as he had seven saves, several of them very good.

The only time he was beat came when Aguilar's ball in to Mendez resulted in a 28th minute goal and a 1-0 lead for Ygnacio Valley.

However, Acalanes struck three minutes before halftime when Max Mirner was perfectly on the end of Nick Warren's free kick to put it away.
