Second-seed Pittsburg’s defense and special teams units shined Friday night, hauling in two interceptions, recovering a fumble and snagging a loose ball during a kickoff en route to a commanding 42-18 victory over No. 7 Liberty in the first round of the North Coast Section Open/Division I playoffs.

Sophomore Isaiah Harrison impacted the game on both sides of the ball, recording an interception, recovering a fumble and reeling off a 23-yard touchdown run.

On offense, senior Carlos Torres and sophomore Javale Jones each had a highlight-worthy touchdown pass. Torres lobbed an end zone fade to senior RJ Mosley Jr. for a one-handed snag while Jones found sophomore Kenneth Ward on a perfectly-thrown deep ball for a 62-yard score. Senior Siotame Finau had two rushing TDs.

Pittsburg is 10-1.
