In Division 1, there were some notable results that could make the postseason feel a little different. Harvard-Westlake, known as a SoCal power and was last year's D1 runner-up, was bounced Thursday by Vista Murrieta in an 8-6 defeat. RJ Holmes and Vaughn Neckar homered in the victory for the Broncos.

Mira Costa defeated Arlington 2-0 to extend its winning streak to 25 straight, and will now take on Arcadia in the second round. Santa Margarita topped Newport Harbor and will play Huntington Beach on Tuesday.

No. 1 Corona and No. 2 Crespi — both with first-round byes — will take on Los Osos and El Dorado, respectively, in the second round.

There were notable performances on Thursday, too.

Norco's Dylan Seward had a homer and three RBIs in a win over Ayala. Crescenta Valley scored three runs in the ninth inning to advance over Santa Barbara in walk-off fashion. Castaic's Gio Foster had three hits and threr RBIs in the first-round win.

Mira Costa's Garrett Jacobs threw a complete game, striking out five and allowing just three hits. Lucien Reed had an RBI triple and teammate Dylan Yencho hit an RBI double in the 7th inning to give Laguna Beach a 7-5 win over Summit.
