PIT BOX: ARCA paying tribute to Greg Biffle this Saturday night at Tri-City Raceway

ARCA Menards Series West teams and drivers will honor the late Greg Biffle and his family Saturday night when the series returns to one of Biffle’s old stomping grounds, Tri-City Raceway in West Richland, Washington, for the running of the NAPA AutoCare 150 Greg Biffle Memorial (8 p.m. PT / 11 p.m. ET on FloRacing).

Biffle spent many of his formative years competing at Tri-City Raceway and nearby Portland Speedway, winning track championships at both facilities before going on to have a long and successful career in NASCAR. Biffle, alongside his wife Cristina and children Emma and Ryder, were among the seven people killed in a plane crash at the Statesville (N.C.) Regional Airport in December.

Saturday’s event will mark the 12th visit for the West Series to Tri-City Raceway dating back to 1968, when Ray Elder led 64 of 100 laps on his way to victory. Other winners through the years at Tri-City include Jim Cook, Jack McCoy, Roy Smith, Dirk Stephens, Mike Chase, Jason Jefferson, Tyler Reif and Kyle Keller.

Tickets to Saturday’s NAPA AutoCare 150 Greg Biffle Memorial are available here. Below is everything you need to know about the sixth race of the 2026 ARCA Menards Series West season.

NAPA AutoCare 150 Greg Biffle Memorial at Tri-City Raceway

Trevor Huddleston’s march toward another ARCA Menards Series West championship is off to a solid start.

Through five races, Huddleston has scored two wins — at Shasta Speedway and Colorado National Speedway — and hasn’t finished worse than fourth. That has allowed Huddleston to build a 20-point advantage on Mason Massey entering Saturday’s NAPA AutoCare 150 Greg Biffle Memorial at Tri-City Raceway.

Huddleston will try to collect his third win of the season Saturday night in the No. 50 High Point Racing Ford, but he’ll face challenges from multiple contenders.

Included among those challengers will be Massey, who won the opening race of the season at Kevin Harvick’s Kern Raceway aboard the No. 19 Chevrolet for Bill McAnally Racing. He and teammate Hailie Deegan should both be quick Saturday night and could be threats to win the 150-lap event.

Jade Avedisian will return to the West Coast aboard the No. 13 for Central Coast Racing, and Robbie Kennealy and Cole Denton will lead the charge for Jan’s Racing Team, which won this event one season ago with Kyle Keller at the wheel.

The full entry list for Saturday’s NAPA AutoCare 150 Greg Biffle Memorial will be available later this week.
