Event Snapshot
Race: Pacific Office Automation 147 (Race 25 of 33)
Location: Portland International Raceway (PIR), Portland, OR
Track: 1.967‑mile, 12‑turn permanent road course
Distance: 75 laps / ~147.5 miles (three 25‑lap stages)
Broadcast: The CW / MRN / SiriusXM NASCAR Radio
Race & Playoff Context
Second‑to‑last regular‑season race — only Kansas remains before the playoffs.
Playoff Bubble: Multiple drivers fighting for final spots; a win here locks them in.
No Cup Series regulars in the field this week — opens the door for full‑time Xfinity drivers to shine.
Defending Winner: Shane van Gisbergen (2024, Kaulig Racing).
Drivers to Watch
Connor Zilisch (JR Motorsports) — Even with injury concerns, he’s the heavy favorite; elite braking and corner‑exit speed.
Justin Allgaier (JR Motorsports) — Consistency king at PIR; thrives in long green‑flag runs.
Sam Mayer (Haas Factory Team) — Aggressive qualifier; needs a win to boost playoff seeding.
Will Brown (Kaulig Racing) — International flair; could surprise if strategy plays out.
William Sawalich (Joe Gibbs Racing) — Rookie debuting at PIR in Xfinity; ARCA West road‑course winner here in 2024.
Track & Strategy Notes
Passing Zones: Heavy braking into Turn 1 and the Festival Chicane; Turn 10 hairpin.
Tire Wear: Moderate — heat in the 80s/90s means rear‑tire management will matter.
Pit Windows: Expect 2–3 stops; under green, fuel window ~28–30 laps.
Cautions: Historically 3–5 yellows; restarts are chaotic into Turn 1.
Win Probability (Top 5)
Connor Zilisch — 41%
Justin Allgaier — 18%
Sam Mayer — 14%
Sheldon Creed — 9%
Will Brown — 6%
Betting Angles
Outright: Allgaier (+800) offers value if Zilisch’s injury limits him late.
Top‑5 Finish: William Sawalich (+5000 outright) — longshot with upside given ARCA success here.
Matchup Play: Mayer over Creed — Mayer’s qualifying edge could control track position.
