BERKELEY -- The Berkeley High boys soccer team was looking to remain perfect in the West Alameda County Conference-Foothill Division, but was facing its toughest task Friday when it hosted top challenger Bishop O'Dowd.

The Yellowjackets not only stayed perfect in league after the 1-0 win, but continued their streak of clean sheets as they still have not allowed a goal in league play.

It wasn't until the 57th minute when Berkeley (11-1-1, 6-0-0 WACC) was able to break through. After an even first half, the Yellowjackets started to create opportunities before Yassine Hamdouni put the game-winner across.

Hamdouni got into the penalty area, was able to split two defenders to get into the six-yard box, then used the outside of his foot to sneak the ball past the Bishop O'Dowd goalkeeper and into the net.

"Jasper (Hebert) found me with a great pass, I saw the seam and got between the defenders," Hamdouni said. "I saw the goalie coming at me, I tried not to hit it too hard and I got lucky enough to get it past him."

The Dragons (5-2-3, 3-1-2) also boast a stingy defense, and had only allowed two goals in league play heading into the showdown with Berkeley.
