CONCORD — De La Salle is back in familiar territory after routing Foothill in the North Coast Section Division I semifinals.

The second-seeded Spartans rolled past No. 3 Foothill 10-1 at home on Tuesday behind a two-home run game from senior second baseman Antonio Castro to advance to the NCS Division I final, where they will play No. 5 College Park at St. Mary’s College on Saturday.

De La Salle (25-4) will be making its 12th consecutive NCS Division I title game appearance. The Concord school has won 30 of its past 31 NCS title games, falling only to Granada in last year’s Division I finals.

“It’s about a lot of hard work,” De La Salle coach David Jeans said. “This team this year, this was their own journey. They were trying to figure it out in the beginning, and sometimes I wondered if they were passionate about it. But they are just quietly competitive, and they’re just figuring it out right now.”

Graham Schlicht pitched a complete game for De La Salle, giving up one run, six hits and striking out six.

“We’re one step away,” said Castro, a Cal Poly commit. “College Park is going to be a tough one, but if we keep working hard like we do, we’ll come out with that.”

Foothill (21-7) got off to a strong start.

Leadoff hitter Jack Fowler hit a home run to right field in the first inning, drawing a burst of loud energy from Foothill’s dugout as he crossed home plate.

But that turned out to be the only run the Falcons scored.

De La Salle tied the score in the home half of the first on a sacrifice fly from designated hitter Bubba Vargas.

De La Salle broke the game open after Schlicht retired three consecutive batters in the second inning.

With one out, Foothill committed an error on a deep fly ball to center field that put two runners in scoring position. After center fielder Alec Blair walked, Castro blasted a drive over the right field wall with the bases loaded to put the Spartans up 5-1.

“I just kept fighting,” Castro said of his grand slam. “I got two strikes and I was just worried about being on time, seeing a pitch I can handle and letting my hands fly.”

From there, it was all De La Salle.

Schlicht continued his dominance on the mound as he kept Foothill’s power hitters in check. The Stanford commit did not see more than four batters in any inning after the early home run.

He finished Tuesday’s game throwing 85 pitches, 57 of which were strikes.

In the fifth inning, Castro and shortstop Tyler Spangler each had a homer as the Spartans put up five more runs to take a 10-1 lead and all but decide matters.

“Hitters did a great job,” Spangler said. “We were seeing the ball well, communicating what the other pitcher was throwing and I think our defense was solid today.”
