ELLENSBURG – East Valley senior Brandon Stone pitched the third-seeded Red Devils past No. 2 Ellensburg on Tuesday in the first round of the CWAC district at Rotary Park.

The Washington State-bound right-hander tossed 6 2/3 innings, scattering five hits and striking out 10 batters against four walks to earn the win and send East Valley to the semifinals, where they’ll host the winner of fourth-seeded Selah and No. 5 Prosser at 1 p.m. Saturday at Loftus Field.

Jaxon Berg broke a scoreless tie in the top of the second with an RBI single that scored Liam Peterson to give the Red Devils a 1-0 lead.

After Ellensburg scored a run on an error in the third to tie the score, Jake Jansen’s bunt single in the sixth allowed Peterson to score again, and Stone and Beyerlein made it hold up.

Berg and Jansen each had two hits for the East Valley (14-6), and Carter Peone was 1 for 2 with two walks for the Bulldogs (13-7).
