The visiting Poets (0-1) took a 17-14 lead early in the third quarter when Mundo Guzman intercepted a Bryan Peterson pass and returned it for a touchdown.
Peterson, a senior from West Valley HS, got the lead back for the Pirates when he ran one in from 14 yards out to make the score 20-17 Whitworth.
Tevin Tyus later returned an interception for a touchdown and DJ Tripoli broke off a 54 yard run for a score to cap off the scoring.
With the win, Whitworth moves to 2-0. They'll play their third straight home game to start the season next Saturday at the Pine Bowl.
