Sacred Heart Prep 4, Mills 0

USC commit Rallin Covey turned in the finest start of his four-year varsity career, firing a two-hit shutout as the Gators (4-1 PAL Ocean, 10-4 overall) earned their fifth straight win at home against Mills (0-3, 3-7). Covey scattered six baserunners, while notching a career-high 14 strikeouts. It marks the third shutout of the senior right-hander’s career, his last coming when he was a sophomore with a three hitter March 15, 2024, in a 4-0 win over Carlmont. His first was as a freshman, April 5, 2023, in a 5-0 win over Rancho San Juan in his varsity debut.

SHP got on the board in the first inning against Mills junior Tino Janke. Senior Nico Pollioni led off with a double, and later scored on a throwing error on a wheel steal. Kyle Sweeney then singled home a run to make it 2-0. In the fifth, junior JP Durrett upped the lead to 4-0 with a two-run double. Durrett paced SHP with two hits. Janke and junior Kendrick Choi recorded the only hits for Mills.

With the win, Covey evens his record at 3-3 with a 1.66 ERA. He now ranks second in the Peninsula Athletic League with 56 strikeouts, trailing Half Moon Bay senior Kai Kung with 57.

Aragon 2, South City 1

The Dons (2-1 PAL Ocean, 9-4 overall) persevered in a 10-inning marathon, walking off on an infield error in the bottom of the 10th with senior Sean Tam scoring the game-winner at home against South City (0-3, 5-9). Nick Mazzola walked to lead off the 10th then promptly stole second base. The junior moved to third on a groundout, prompting the Warriors to walk Tam intentionally. After Tam stole second, the Warriors cut down Mazzola at the plate on a grounder to freshman third baseman Dylan Munsayac. Then with two on and two out, sophomore Justin Wright hit a grounder that was booted to bring home Tam to end it.

Wright earned the win with three shutout innings of relief, upping his record to 2-0. The sophomore right-hander took over for senior Xavier Ruiz, who allowed one run on six hits through seven innings of work while maxing out at 110 pitches. South City junior Vince Bernal took the loss, allowing one unearned run through 1 2/3 innings. Warriors starter Emilio Oseguera worked eight innings, allowing one unearned run on five hits and throwing 108 pitches.

Nicholas Jang sparked the go-ahead rally with a one-out triple, setting the table for an RBI single by Hunter Tamayo. Carlos Alcala followed with a triple to right to drive home Tamayo. Adrian Iniguez then produced an RBI groundout to cap the rally.

Jang paced El Camino with three hits and an RBI to improve his season average to .432.
