THE PREPS : Eagles Claw Glendora, 41-6 : Football: Santa Margarita’s Harrison, a raw reserve, plays like a veteran in first half.

Santa Margarita put together an outstanding defensive effort for three quarters Saturday night, but it was the steady play of an untested senior quarterback that highlighted a 41-6 nonleague victory over Glendora at Citrus College.

Craig Harrison, who had not taken a snap in more than two seasons because of injuries, completed seven of 10 passes for 101 yards and one touchdown. But more importantly, he exhibited the poise and direction not usually seen from a raw reserve, helping the Eagles (2-0) to a 21-0 halftime lead.

Harrison was replaced in the second half by Chris Collins, who is projected to be the Eagles’ starter for the rest of the season. Collins sat out the first 24 minutes because an illness prevented him from attending a practice earlier in the week. He too, was sharp, completing five of eight passes for 113 yards and a score. That touchdown came on a 62-yard pass to Matt Nickels early in the fourth quarter.

By that time, though, this one was already in the books. Glendora had only one yard of net rushing (six total for the game), and the only thing that remained was to see if the Eagles could preserve their second consecutive shutout. Santa Margarita defeated Trabuco Hills, 20-0, last week.

Glendora (0-2) scored on an eight-yard pass from quarterback Jonathon Smith to running back Brent Frahm with 6:45 left to play.

Santa Margarita Coach Jim Hartigan appeared impressed with Harrison, who has had a series of shoulder separations that have sidelined him since November, 1992.

“I thought he played with poise and he threw some nice balls,” Hartigan said. “It’s good to know we have him. We may use him down the road.”

Santa Margarita scored first on a 13-play, 85-yard drive that was capped by running back David Munoz’s three-yard run. Munoz set up his scoring run with a 24-yard run on the previous play to the Glendora 27-yard line.

The Eagles followed with a 10-play, 51-yard drive capped by Harrison’s six-yard pass to tight end Eric Brown on second and goal from the Glendora six.

Bryce Jackson blocked a Glendora punt and Santa Margarita took over at the Glendora 18-yard line. The Eagles worked the ball down to the seven-yard line, where the drive stalled when Glendora shut down a fake field-goal try on fourth down.
