Previewing

The Southern Section will hold nine baseball championship games this weekend, led by the Division 1 final at 7 p.m. Friday at Cal State Fullerton between St. John Bosco and Norco.

Here’s a look at top matchups:

FRIDAY

Division 1: St. John Bosco vs. Norco at Cal State Fullerton, 7 p.m. Both schools will have their top pitchers ready to go, which means runs will be at a premium. Julian Garcia of St. John Bosco was in the dugout last season when the Braves won the title but couldn’t play as he was rehabbing from Tommy John surgery. He’s come back with a flourish, going 8-1 with a 0.88 ERA. All the Braves’ key pitchers are available, including closers Jack Champlin and Brayden Krakowski. Norco will start Jordan Ayala, who shut out Orange Lutheran in the quarterfinals. It’s going to come down to defense and someone getting a clutch hit against very good pitching.

SATURDAY

Division 2: Ganesha vs. Loyola at Rancho Cucamonga Quakes, 5:30 p.m.: Likely first-round draft pick Logan Schmidt will be on the mound for Ganesha, offering a huge challenge for the Cubs. He’s also the team’s top hitter. Loyola has faced top pitching all season in the Mission League and will have rising freshman Sheriff Hall on the mound. The Cubs also have players who can hit home runs, such as Jack Murray and Luca Marucci.

Division 3: Mira Costa vs. Agoura at Cal State Fullerton, 4 p.m.. Both schools have prom in the evening, so watch for players rushing to cars after the game. Mira Costa has somehow made it to the final despite losing its No. 1 and No. 2 pitchers to injury. Others have stepped forward, and the hitting attack has been good in the playoffs. Austin Olness hit a two-run home run in a 12-0 semifinal win over St. Francis. Agoura, under first-year coach Adam Goldstein, is another overachiever. Senior Tyler Starling hits and pitches with the best, but it’s been underclassmen pushing the Chargers toward a title.

Division 4: Glendora vs. Laguna Beach at Cal State Fullerton, 7:30 p.m. Senior Tanner Grable leads Glendora with 36 hits and four home runs and also can pitch. Junior Dylan Yencho is having a big season for Laguna Beach, batting .455 with 50 hits and an 0.94 ERA as a closer.

Division 5: Kaiser vs. Culver City at Rancho Cucamonga Quakes, 11 a.m. Senior Tino Cuellar is Kaiser’s leadoff hitter with 34 hits. Culver City finished second to Santa Monica in the Ocean League and has a productive freshman in Matthew Riesenberg, who has 36 hits, a .431 batting average and 29 RBIs.

Division 6: Brentwood vs. Covina at Cal State Fullerton, 1 p.m. The Eagles won’t have ace Jack Kaplan available after he threw a shutout in the semifinals, but there’s plenty of hot hitters, including junior Hudson Chase, who has 42 hits and seven home runs. Covina, which knocked out Lakewood and longtime coach Spud O’Neil in the semifinals, was second in the Valle Vista League to Charter Oak. Senior Lucas Thorpe has been providing key hits all season, including four in the semifinals.
