Archbishop Mitty High-San Jose took a tense 2-0 victory over California on Friday to clinch a berth in the Championship Flight of the Livermore Stampede at Robertson Park.

The Monarchs (14-0), ranked No. 6 in the Cal-Hi Sports state softball rankings, prevailed over the 12th-ranked Grizzlies (8-2) with two runs in the top of the sixth inning, helped by back-to-back errors and a catcher's interference call to lead off the inning.

Mitty's Ashley Chestnut hit an RBI single with the bases loaded, bringing in Danielle Bowers. Courtesy runner Anissa Bonilla scored on a wild pitch.

The game pitted teams with 2-0 records in Pool D of the 16-team event, which wraps up with four flights Saturday.

The Monarchs will face Whitney, the winner of Pool C, at 3:15 p.m. in the Championship Flight semifinals. Livermore and Monte Vista, both 3-0 in pool play, will meet in the other semifinal at 3 p.m. The championship game is at 7:15 p.m. at Robertson Park.

"That's a really good team," California coach Joe Callaway said of Mitty. "We made two errors. Good teams capitalize on another team's mistakes. That's what really nailed that down, but they're a good team. They had the pressure on us the whole game."

The game featured a pitchers' duel. California's Lindsey Chalmers, a Cal Poly commit, struck out 12 and allowed seven hits. Mitty's Desiree Severance fired a three-hitter and was backed by a strong defense from shortstop Jazmyn Jackson and second baseman Catherine Callaway.

The Grizzlies' Kwyn Cooper singled with one out in the bottom of the sixth, but Severance retired the next two hitters. The game then was called because of the 90-minute time limit.

California freshman catcher Rachel Marchuk made a strong statement early, throwing out two runners attempting to steal second, including the speedster Jackson. California will face Pleasant Grove-Elk Grove in the Stampede Flight at 11:15 a.m.

Grizzlies No. 2 starter Katelyn Linford allowed no hits in a 13-0 rout of Castro Valley in a five-inning game that preceded the matchup with Mitty.

Amador Valley 3, Righetti-Santa Maria 0: Johanna Grauer fired a one-hitter with nine strikeouts and no walks as the Dons (10-1) advanced to Saturday's consolation final of the Michelle Carew Classic at Canyon-Anaheim. Amador Valley has won three games since an opening-round 3-1 loss to Yorba Linda on Thursday.
