Glendale Eliminated by Rancho Santiago : Men’s soccer: Vaqueros lose playoff match, 1-0, in overtime. They finish 15-1-5.

SANTA ANA — Rancho Santiago’s Francisco Islas was kept silent during most of Saturday’s Southern California men’s soccer playoff match against Glendale.

But Islas didn’t let up.

His persistence paid off with the game-winning goal in the 117th minute, sending the host Dons to a 1-0 victory.

Islas, who scored nearly half of Rancho Santiago’s goals this season, was limited to three shots during regulation and was not a factor during most of the overtime. But with three minutes left in the extra period, he took a rebound from Andrew Otelie on the right side of the goal and banked in the game-winner off the left post.

The goal spoiled an outstanding performance by Glendale goalkeeper Erick Alvarado, who made 17 saves.

Glendale (15-15) had only six shots and Rancho Santiago goalkeeper Scott Zinser didn’t record a save.

“We were all over them, and we finally executed,” Rancho Santiago Coach J.P. Frutos said.

The Dons (17-2-3) dominated the first half, outshooting Glendale, 11-3. Rancho Santiago’s best scoring opportunity came when Arthur Salce’s header hit the crossbar at the 25-minute mark.

Glendale’s best scoring opportunity came midway through overtime, but Giancarlo Madariaga’s shot on a breakaway went wide left.

“(Rancho Santiago) deserved to win,” Glendale Coach Joe Agoston said. “Our game never really developed. We were sloppy in the first half, and settled down in the second. I don’t think we were mentally ready to win at this level.”
