The first home run hit at Clayton Valley Charter High's baseball field since 2012 kept the Eagles' unbeaten season intact.

Ethan Utler crushed a high fastball for a two-run shot in the fourth inning as Clayton Valley rallied past Northgate 2-1 in Diablo Valley Athletic League action on Thursday.

The Eagles improved to 17-0 overall and remain alone in first place in the league standings with an 8-0 record.

Utler's blast, just the second of his high school career, was a moonshot that coach Casey Coakley estimated traveled about 350 feet.

"I was looking for a fastball and I got it," the senior catcher said. "Our pitcher A.C. was (dealing) on the mound and I just wanted to get him some run support."

It ended up being just enough for starter Austin Cannedy, who scattered seven hits and struck out eight in the complete game effort.

"Austin's been very steady," Coakley said. "He's been getting better as games go on and again today he got into a groove as the game went on. We just needed to get him a couple runs with a timely hit and we made it stand up on the mound and on defense."

Northgate (11-5, 6-4) led briefly after stringing together three straight hits off Cannedy in the top of the fourth. An infield single from Eric Huang drove in Ryan Strong, but the rally ended a batter later when Clayton Valley second baseman Gabe Taylor made a diving grab then doubled the runner off first base to end the inning.

Utler then gave Clayton Valley the lead for good after Garrett Nelson drew a one-out walk. Utler's big hit was one of just four off three Northgate pitchers.

The come-from-behind win completed a regular season sweep of Northgate and was the Eagles' sixth win by a single run.

It's all part of what's shaping up to be a special season for the Eagles.

"(The winning streak) is something we don't really talk about," Coakley said. "I don't think we've brought it up once. We have a good group of guys that show up and work extremely hard to be good ballplayers, and we really pride ourselves on staying in the moment."
