Sierra High used one third-inning Iyana Hughes run to slip past Pitman 1-0 and then exchanged shots with Los Banos for a six-inning 4-4 stalemate in the Ceres Tournament Friday in Riverbank.

The Timberwolves (2-0-1) got a sterling effort from starting pitcher Allison Walljasper. Walljasper was effective and efficient, striking out 14 batters and surrendering just two hits in the win. Walljasper’s dominance continued in the Los Banos matchup, holding the tigers to a hit and nine strikeouts. Defensive miscues enabled the Tigers some success.

“We had our second catcher in there and she had never caught Ally, so there were some issues there,” Sierra head coach Nick Olmo said. “Overall, she did a great job. She really pitched well in both games, but Los Banos was able to put the ball in play.

“They only had the one hit, but they put her in play more than Pitman did.”

Both Hughes and Walljasper had doubles in the Pitman win, while Gianna Lenoci and Elena Flores both were 1-for-2 in game two.

The Timberwolves will return to tournament action against Hughson and Johansen. Hughson is scheduled for a 4:30 p.m. start, while Johansen is slated for a 6:15 p.m. first pitch.
