St. John Bosco stuns No. 1 Corona 2-0 in Southern Section Division 1 semifinals

Jack Champlin, a junior pitcher for St. John Bosco, surveyed the memorable scene Tuesday afternoon. There were fans standing everywhere — down the lines, around the outfield walls, in the press box. It was the top of the seventh inning, and No. 1 Corona had two runners aboard trying to rally in the Southern Section Division 1 semifinals.

“I love it,” he said. “There’s close to 1,000 people and it’s electric. I didn’t feel any pressure, didn’t feel nervous.”

He got a strikeout and fly ball to save St. John Bosco’s stunning 2-0 victory over Corona and unbeaten pitcher Seth Hernandez, who had never lost in two years of high school baseball.

“Tough day for people who don’t normally have tough days,” said Corona coach Andy Wise, who guided the Panthers to the Division 1 title last season and saw his team’s record drop to 28-3.

The Braves will play Trinity League rival Santa Margarita in Friday’s 7 p.m. Division 1 championship game at Cal State Fullerton.

Everything St. John Bosco needed to do to pull off victory happened. Left-hander Trevor Heishman gave up one hit in 6 1/3 innings with nine strikeouts. He struck out Corona’s hottest hitter, Anthony Murphy, three times.

The Braves refused to be intimidated by the 99-mph fastball of Hernandez, who came in with just four walks and 96 strikeouts in 48 2/3 innings and an 18-0 record in high school baseball. He struck out nine, walked three and gave up a run in the second inning on consecutive singles by Champlin and Macade Maxwell. St. John Bosco scored another run in the fifth on a Hernandez balk.

“He’s just another player like us,” Champlin said of the Braves’ attitude toward Hernandez, one of the top pro prospects in the nation. “We weren’t scared. We came out with confidence we were going to win from the time we stepped on the field.

Champlin was brought in with one out in the seventh after Heishman walked one batter on four pitches and went to a 2-0 count on the other. Champlin walked the batter but didn’t let the Panthers get anymore chances.

In two years as head coach, Andy Rojo has taken the Braves to the Division 3 final (last season) and now the Division 1 final on Friday.

His batters made Hernandez throw 92 pitches in five innings and hit the ball hard when they needed. “The key for us we wanted to put the ball in play,” he said.

St. John Bosco has never won a section baseball title after all the success the football and basketball teams have had. But this 26-4 team won the Trinity League championship for the first time since 2017 and has beaten Santa Margarita two of three times this season.

And they’ve got Champlin ready to be the closer again on Friday.

“I haven’t had a blown save,” he said with the confidence of a true closer.

Santa Margarita 12, Crespi 0: Ben Finnegan had three hits and four RBIs and Brennan Bauer gave up two hits in five scoreless innings to send the Eagles (20-12) into the Division 1 championship game. Bauer has pitching victories in all four playoff games and has allowed one earned run in 17 1/3 innings.

Mater Dei 5, Fountain Valley 4: A three-run sixth inning propelled the Monarchs to the comeback win in the Division 2 semifinals. Lawson Olmstead broke a 4-4 tie with an RBI single. Brandon Thomas picked up the save in the seventh and will pitch in the championship game.

West Ranch 8, Etiwanda 7: Ty Diaz had a walk-off single in the bottom of the eighth inning, culminating in a three-run comeback victory in the Division 2 semifinals. Etiwanda took a 7-5 lead with two runs in the top of the eighth. Diaz finished with three hits and two RBIs.

San Dimas 4, Beckman 1: The Saints advance to the Division 3 championship game. They will face Glendora, a 7-5 winner over Temecula Valley.
