With the win, the fourth-seeded Eagles next host the winner of today's Brawley Union-St. Augustine clash. That game will be contested at Southwest on Saturday. Game time is to be determined.
"It was a pretty physical game, especially in the second half," Contreras noted.
It was also physical in the first half.
In the opening five minutes, Southwest's Juan Garcia was taken down from behind in front of the goal. Renteria had passed the ball to Garcia, who slipped behind the Centurion defense.
A University City defender raced in and clipped Garcia from behind. No foul was called.
Garcia had to be helped off the field and remained sidelined for more than five minutes while trying to massage a muscle.
Less than five minutes later, Renteria scored off a penalty kick.
Joshua Mora had passed the ball to Renteria, who broke into the open. He, too, was tackled from behind and this time a foul was called.
Renteria's penalty kick sizzled along the ground into the left corner of the net.
Just before halftime Renteria scored a goal, putting a move on two defenders and spinning 360 degrees before lofting a shot that sailed over the Centurion goalie's head.
In the second half Luis Montes provided the most pressure on University City's defense, getting off three shots on goal. One just missed as it sailed inches over the crossbar.
Most amazing was the fact Montes was playing somewhat hampered by a yellow card he had picked up in the first half. It was one of six yellow cards issued in the game, with the Centurions being flagged four of the time.
Mora, Armando Burke and Garcia also had shots on goal for Southwest (16-5-3).
