The way Valley Christian’s pitchers were throwing, the Warriors may have quite a bit of success for the rest of this playoff season.

Valley put on a pitching showcase in a Central Coast Section Division I semifinal on Wednesday night at Excite Ballpark in San Jose, holding Los Gatos to just a pair of runs and consistently escaping jams by limiting the damage. And the Warriors finally gave their hurlers some run support in the late innings, plating one in the fourth and three in the fifth.

That was plenty on a night where starter Quinten Marsh and reliever Rohan Kasanagottu combined to allow one earned run and strike out 11 batters, powering Valley Christian to a 4-2 win.

“It might be as deep as five sometimes,” Valley Christian coach John Diatte said of his rotation.

Valley Christian (25-6-1) advanced to face Serra in the Division I championship game on Saturday night at Excite Ballpark on the backs of its two pitchers who are committed to schools within the old Pac-12 footprint.

Marsh, who is headed to Stanford next year, set the tone with 4 1/3 shutout innings. Then he handed the ball off to Kasanagottu, a USC signee, who navigated some traffic in the sixth to keep the train on the tracks.

Los Gatos (24-5) made its biggest push in the penultimate frame, plating back-to-back runs on a single by Will Temple and a wild pitch. But when Temple tried to score on another wild pitch later in the inning, Valley Christian got the out.

Division II

No. 5 Wilcox 8, No. 8 Capuchino 2: Jake Prettol had two hits and knocked in three runs and Matthew Tiendas tripled, doubled and scored three times to lead Wilcox to a victory over Capuchino in a semifinal at Santa Clara University. Wilcox (21-8) will play third-seeded Hollister for the championship on Saturday at Excite Ballpark. Mateo Escobedo pitched four scoreless innings for Wilcox to close out the victory, striking out five and allowing one hit. Wilcox led 3-0 after the first inning. Capuchino cut the margin to one with two in the third, but Wilcox pulled away with three in the fifth and two in the sixth.

No. 3 Hollister 8, No. 2 Menlo-Atherton 2: The Haybalers made fast work of M-A, scoring five runs in the third inning for a 7-0 lead. The Bears (21-8) didn’t score until the bottom of the seventh when a pickoff attempt with a runner on third was thrown away. Ryder Kelly singled for M-A’s second run.

Division III

No. 3 Willow Glen 10, No. 7 Los Altos 8: Despite being outhit 6-4, the Rams will play in the D-III championship game against Carmel on Friday at Santa Clara University. Willow Glen was assisted by seven walks and four Los Altos errors. The game’s turning point was the bottom of the fifth, when the Rams (23-6) scored six runs. Triples by Miles Austin and Ben Mudgett accounted for all but two runs. Austin’s triple came with the bases loaded. Willow Glen trailed 4-2 before the six-run uprising. Joshua Kaminski drove in three runs for Willow Glen.

No. 1 Carmel 2, No. 5 Christopher 0: Carmel scored a run in the first and one in the fifth, which was plenty to end Christopher’s season as Kenny Sanchez and Ty Arnold combined on the shutout. Sanchez scattered six hits over five-plus innings and Arnold retired all six batters he faced to send Carmel (19-10) into the final.

Softball Open Division

No. 2 St. Francis 6, No. 6 Salinas 1: Hayden Hummel got it going for the St. Francis softball team with a second-inning home run right down the left-field line.

The rest of the Lancers took it from there, adding another run in the third and four in the fifth in a win over Salinas in a CCS Open Division semifinal game at West Valley College.

No. 2 seed St. Francis (27-3) will play undefeated top seed Willow Glen for the CCS Open championship on Saturday at 3 p.m. at West Valley College.

The Lancers are the defending CCS Open champions and have won three of the last four Open titles. But this year they are seeded behind a Willow Glen team they have always dominated in the past.

But don’t expect St. Francis to be riled up over a perceived slight.

“They’re undefeated, they’re a senior-heavy team, they have the best pitcher in the section,’’ St. Francis coach Mike Oakland said of Willow Glen. “They’re a very, very good team and I thought the seeding was spot on.’’

Nevertheless, the Lancers are, year after year, in a category all by themselves when it comes to hitting the long ball. Hummel’s home run was the team’s 28th of the season.

“After the first inning when we went down 1-2-3 it helped us go, `Oh, we can hit this kid, ‘’ Oakland said.

Division II

No. 1 Hillsdale 2, No. 4 Notre Dame-Belmont 0: Lola Jones scattered four hits and four walks and struck out 11 to lead Hillsdale into the Division II final with a victory over Notre Dame at Capuchino High. Jones and Taylor O’Mahony each knocked in a run in the first inning, providing all the run support Jones would need. Hillsdale (18-9-1) will play crosstown rival San Mateo for the title on Saturday at West Valley College.

No. 7 San Mateo 2, No. 6 Everett Alvarez 1: The Bearcats are headed to the D-II championship game, with a roster made up entirely of freshmen and sophomores. Shortstop Alice Han, a sophomore who leads San Mateo (16-9) with 37 runs scored, 25 RBIs and 17 extra-base hits, drove in the winning run Wednesday with a two-out single in the top of the seventh at Capuchino High. Destina Zhou began the winning rally with a two-out single. She then stole her 12th base of the season and came home on Han’s single to center.

Division III

No. 4 Westmont 2, No. 8 Mountain View 1: Regan Steele allowed one unearned run in a complete-game gem and Melia Andrade and Maddie Crowley each drove in a run to lead Westmont over Mountain View in a Division III semifinal at MacDonald High. The Warriors advance to play second-seeded Aptos for the championship on Saturday at San Jose City College.

Division IV

No. 3 Woodside 2, No. 2 Watsonville 1: Woodside scored two runs in the first inning, and that would turn out to be enough to beat Watsonville at Los Gatos High. Ava Baker had the big hit for the Wildcats (15-11), lacing a two-run double to center field to score Caroline Ong and Vanessa Carlos. Hannah Walker took care of business in the circle, allowing one earned run on four hits with four strikeouts in seven innings. Woodside will face No. 8 Palma for the championship on Saturday at San Jose City College.

Division V

No. 2 South San Francisco 11, No. 3 Soledad 1: South San Francisco steamed into the Division V championship game with a five-run first inning in a game that ended by run rule after five innings. Sydney Semans drove in three runs for SSF (16-8), and Miley Salvatore plated two for South City, which will take on King City for the title at 12:30 p.m. on Saturday at San Jose City College.
