Ryan Mo had two hits, including a double, and battled into the fifth inning fro the mound, though the Palo Alto Babe Ruth 14-year-old all-star team could never gain the upper hand and Tri-Valley won, 7-0, to advance into the southwest regional.
Palo Alto was down 2-0 heading into the fifth, when Tri-Valley, the defending Babe Ruth World Series champion, put together a five-run rally.
Jack Grant turned out to be the main thorn, as his three-run homer in the fifth proved too much to overcome.
Mo retired the first two hitters in the inning and appeared to have struck out the next batter but didn't get the call, ending up issuing the only walk of the contest. Two batter later, Grant connected on a 0-1 pitch.
Palo Alto had its own two-out rally in the second. Ian Collins and Aidan Everett singled before Tri-Valley got out of the inning.
Charlie Giesler and Paul Thie each singled with two outs in the third but the Tri-Valley second baseman made a nice stop on a hard grounder to prevent a run scoring.
Mo doubled with one out in the seventh and Everett was hit by a pitch one out later. Trevor Leon then drilled a liner down the third base line that was somehow caught, ending the game.
