LAFAYETTE -- The Acalanes High boys lacrosse team earned its second trip to the North Coast Section Division II championship game in three years Wednesday as Wesley Greason scored a game-high five goals in a 12-9 semifinal win over visiting Piedmont.

No. 2 seeded Acalanes (18-4) will face No. 1 Marin Catholic-Kentfield (17-6) in the finals at 4 p.m. on Friday at Dominican University in San Rafael.

It will be a rematch of the 2011 championship game, which was won 8-7 by Marin Catholic.

"We're one step away, but we're not satisfied until we get it," Acalanes coach Brent Ringwood said of the semifinal win. "It's big, but we want the next one."

Acalanes, which staved off a late surge by Piedmont (18-3), got a big game from Scott Lindsay, who won almost every faceoff, and Robbie Stern, whose third goal made it 12-8 with 1:35 left.

Ringwood raved of Lindsay's dominance on restarts, which allowed the Dons to slow the explosive Highlanders momentum.

"He's been doing that all year long," Ringwood said of Lindsay. "He's gotten us out of some really tight jams. He's the guy that as soon as a team goes on a run, he's the like a run-stopper. He essentially wins the faceoff and gives us possession just about every single time. He's been really big for us."

Piedmont's Mark Bublitz led his team with three goals and two assists.

Ringwood said his team's defense was "amazing" and goalie Cameron Bosshart (13 saves) "really stepped up."

Greason, the MVP of the Diablo Foothill Athletic league, scored a brilliant goal with 43 seconds left in the first quarter to put Acalanes ahead 2-1 and spark the offense. On the play, he faked a pass before cutting across the middle from the left.

Greason tacked on the next two Dons' goals before Stern, using sweeping, powerful left-handed deliveries, scored twice in the final 5:37 of the first half to make it 6-3.

The lead grew to 8-3 on back-to-back goals by Jack Mariani and Lindsay, who made a long run up the middle. The Highlanders cut the deficit to four on a nifty goal by Bublitz on a counter, but Bosshart followed with a big save on Bublitz. Greason struck again with 1:53 left in the quarter after charging from behind the goal and wheeling for the shot.

Bublitz scored off Ryan Ellis' second assist of the match to cut the deficit to 9-5, before Ellis scored with a bouncing shot. However, Acalanes surged again on clutch goals by Pete Mitchell and Sam deRoque, on a putback.

Piedmont responded with goals from Ellis and Jack Moe to cut it to 11-8 before Stern's back-breaker.

"They played really well," Ringwood said of his team. "We had sone really good individual performances at the beginning, and then they started sharing the ball a little bit, and it really looked like a team effort by the end."
