Freshman tailback Bill Chimphalee gashed Southwestern for 161 yards on 18 carries to do the bulk of the ground work for an OCC running game that utilized 10 ballcarriers. Chimphalee, whose one-yard touchdown run capped the Pirates' eight-play, 70-yard opening possession, sprinted 65 yards for his second score on the hosts' first offensive snap of the second quarter.
Chimphalee's long touchdown run gave OCC a 17-3 cushion that increased only 104 seconds later when Keali'i Doll returned a punt 70 yards for a touchdown that gave the Pirates their 24-3 halftime lead.
After a scoreless third quarter, OCC freshman Robert Penny scored on a one-yard run just 26 seconds into the final period.
After Southwestern answered with a three-play touchdown drive kick-started by a 49-yard kickoff return, OCC's Steven Hauptmann recovered an onside kick at the Southwestern 39.
That's when OCC offensive coordinator Junior Tagaloa went for the Jaguars' jugular, calling for a flea-flicker that put Doll alone behind the secondary awaiting a pass from freshman quarterback A.J. Josue. But Josue's toss went long and the Pirates kept the ball on the ground 20 of their final 21 plays.
Sophomore Kaiona Dutro ran over a defender at the goal line for a 14-yard touchdown to finalize the scoring with 8:04 left to help OCC claim victory for only the second time in its last 14 conference games.
The OCC defense also showed its muscle, intercepting four passes and limiting Southwestern to 23 yards on 20 rushing attempts.
Sophomore cornerback Joe Galvez had the first three picks for the Pirates, who received a fourth from freshman corner Clay Guess.
But the secondary was far from the only heroes for the Pirates, who stopped Jaguar rushers at or behind the line of scrimmage nine times. In addition, eight of Southwestern's pass completions resulted in four or fewer yards.
Tackle Isaiah Reupena, linebackers Eric Wiersma and Earnie Saigao and end Bryce Brantley spearheaded a front seven that seemed to find as little trouble dominating the neutral zone as the Pirates' offensive line.
