Escondido goalkeeper Gustavo Rodriguez came off his line to cut off the angle. Mora shot as Rodriguez was charging.
The ball was rolling into the goal when McClain tried to control it but instead the ball became entangled in his legs, then passed through his legs into the goal.
The second goal for Calexico came 10 minutes later when the Escondido defense was rushing out of the penalty box after it had punted the ball forward.
A Calexico player headed the ball back toward the Escondido goal and it landed at Cruz's feet leaving, him alone against Rodriguez.
Cruz beat the goalkeeper to give Calexico a 2-0 lead.
In the 30th minute of the second half Noe Luna of Escondido received a second yellow card and was sent off the field.
Luna was slide-tackled by a Calexico player but referee Jesus Sanchez thought Luna caused the foul and carded him. Escondido's side protested heavily.
In the last minute of the game Calexico's Omar Retana also received a second yellow card and was sent off after he was apparently taunting an Escondido player by staring at him.
Escondido would score its only goal in the fifth minute of injury time when Andrew Peters pushed the ball in off a free kick taken from the right side of Calexico's penalty box. Escondido's Edwin Juarez had centered the ball close to the goal and Calexico goalkeeper Jose Garcia could not clear it and Peters simply pushed the ball in.
Pascual Gonzalez, Calexico's head coach, said, "We just wanted to simply win the game."
Dominick Lane, Escondido's head coach, said, "I thought they played well and they are a good team. I wasn't happy with my team's effort."
Calexico will travel Friday to San Pascual High in Escondido for the second round of the CIF playoffs.
