On Mt. SAC's third play, Fadden connected with Walker again for a 64-yard strike, as only Walker's stumble after hauling in the deep pass kept the play from being another touchdown.
The drive ended with a missed 25-yard field goal attempt and OCC capitalized on a muffed punt reception to score with 1:44 left in the first period.
But Fadden went back to work on the second play after the ensuing kickoff, hitting tailback Antonio Williams in stride on a wheel route for a 34-yard gain to the Pirates' 35-yard line.
Fadden then flipped it to Williams in the flat and he ran over OCC safety Benjamin Soza on his way to a 35-yard touchdown.
Jeremy Gener kicked the conversion to make it 14-6 with one second left in the first quarter.
OCC, which played without sophomore quarterback Kekoa Crowell (injured elbow), answered on its next possession with some aerial fireworks of its own.
Freshman quarterback Chris Debowski, who had completed just five passes coming in, found sophomore wideout Damola Adeniji for a 64-yard gain to the Mounties' five-yard line. The big play set up a Debowski fade pass to Adeniji for a four-yard score and Debowski threw to George Raco for the two-point conversion to tie the score with 12:19 left in the first half.
That's how the half ended and Mt. SAC Coach Bob Jastrab sent Fadden out of the halftime locker room with a different plan of attack.
While the Mt. SAC defense, which led the 12-team Mission Conference in fewest rushing yards allowed, was holding the Pirates to just 26 yards on 29 rushing attempts, Fadden utilized the short pass to compile points and consume time.
With the OCC secondary allowing plenty of cushion, Fadden had completions of five, four, six and four yards on a seven-play, 76-yard scoring drive that was aided by an OCC roughing-the-punter penalty.
