The key to the win was Burroughs' short-handed defense, as Bonita (6-18; No. 3 from the Hacienda League) earned 10 ejections, but scored just two goals on man advantages.
"That was big right there," Burroughs Coach Danny Garcia said. "Our defense really stepped it up on those ejections and that made the difference."
Daniel Mairena had three goals and Casey and Kevin Ueno added two each. In goal, keeper Dillon Weigand had 12 saves.
"It was a tight game throughout the first three quarters," Garcia said. "We just had a little more in the fourth."
The Indians will play at Riverside Poly in a first-round match at 5 p.m. Wednesday.

"I was very happy with the way we played in three of the four games," said Providence Coach Josh Eggleston, whose team ends the season 9-11 after finishing fourth in the Liberty League. "This is probably one of the best games they've played all season.
