You can’t afford to make a mistake against Sierra High.

Justin Coenenberg, the Manteca High girls’ soccer coach, echoed just that following his team’s 5-0 Valley Oak League loss at Guss Schmiedt Field on Monday.

“They capitalized on every opportunity,” he said of the first-place Timberwolves (8-0, 21-2-1).

Cal-bound Jadyn Shinn scored three times and Tiana Cello netted two in the intercity rivalry matchup to the Buffaloes (4-3-3, 7-7-5).

“It’s always cool (for us) to win these rivalry games,” Shinn said. “It helped that we came out strong.”

Rewind to the 10th minute as she capitalized on a through ball by Cello. Shinn suddenly found herself one-on-one with the goal keeper, scoring to give her team a 1-0 lead.

At the 30th minute, Preeya Singh of Sierra was tripped up by Manteca defenders. Enter Cello, who took the penalty kick.

“The past few games I’ve been asked to handle the penalty kicks. That shows that my teammates have confidence in me – I didn’t want to let them down,” she said.

Cello delivered, giving her team a 2-0 lead.

Sierra made it 3-0 at the 38th minute, with goalie Callie Crain punching out a long ball and Shinn converting on the play that took place shortly before the break.

“Manteca really played us hard, challenging us on every step,” Timberwolves coach Manuel Pires said.

Jordyn Silva and Mia Treacy, both sophomores, were among the Buffalo defenders who helped fend off several attacks from Sierra’s potent offense.

Cello, who took a pass Shinn – the senior midfielder / striker drew a pair of defenders to her side to help pave the way for the sophomore forward’s corner kick – punching in her second goal at the 69th minute.

The Timberwolves added the final touches in the 77th minute.

Julianna Rodriguez’s corner kick enabled Shinn to score at close range.

Pires, in addition, praised his defense.

“Everyone played well – Callie (Crain) has stepped up as our goalie,” he said.

Sierra will travel to Central Catholic on Thursday while Manteca will host Weston Ranch on Friday for The Kick for A Cure fundraiser benefiting MHS teacher Amy Gross, who is receiving treatments for stage IV non-smoker lung cancer.

In the junior varsity game, Sierra won, 2-0.
