Sequoia 6, Los Altos 5

The grand slam parade just keeps trucking down Brewster Avenue, as the Ravens (14-10) powered to another late comeback victory to top visiting Los Altos (11-14). Trailing 5-0 in the fourth, Sequoia got on the board with a solo home run by senior Mario Fausto. But the big blast came in the fifth, when Mario’s twin brother, senior Nolan Fausto, came to the plate with the bases loaded and promptly went grand salami over the center-field wall to tie it 5-all.

It marks Sequoia’s fourth late-inning grand slam of the season to either tie or win a game.

Junior catcher Connor Murray then got in on the power shot, leading off the sixth with a go-ahead solo home run that proved to be the game-winner. It’s the second home run of the year for Murray, who hit his first varsity bomb Friday. He has now homered in back-to-back games.

Half Moon Bay 3, Santa Cruz 0

Right-hander Tristan Castro became the third straight Half Moon Bay starter to record a shutout, as the Cougars (15-9) claimed a non-league win at Santa Cruz (13-10). Making his third start of the year, Castro went the distance, allowing five hits and one hit batter, while striking out three to earn his first varsity win. The junior was hyper-efficient, needing just 68 pitches through seven innings, 46 for strikes.

Junior Cole Giannini went 2 for 3 with an RBI triple, while juniors Lane Giannini and Paxton Holden also drove in runs.

Holden was the shutout hero in Friday’s 6-0 win at Aragon, going the distance for his first career victory. Senior left-hander Kai Kung started the streak last Wednesday with a two-hit shutout in a 5-0 win over Aragon on the Coastside. HMB pitching has now gone 26 straight innings without surrendering a run.

Juniors JP Durrett and Thomas Barton drove in runs for the Gators.

Mills 14, Hillsdale 13

The Vikings (5-17) snapped a nine-game losing streak with a wild back-and-forth win at Hillsdale (10-14).
