Pirelli GT4 America SprintX returns to action this weekend at Portland International Raceway, with 20 cars on the entry list for the combined SprintX/GT4 West round.

The SRO Motorsports America event, which will also include TC America competitors, will serve as the prestigious Rose Cup races at the 12-turn, 1.945-mile circuit.

GT4 America Sprint, meanwhile, will not be in action this weekend.

Nolasport’s Matt Travis and Jason Hart head into the weekend as the dominant driver pairing in SprintX Pro-Am competition so far, with five wins in eight races.

The No. 47 Porsche 718 Cayman GT4 Clubsport has failed to finish off the podium this season, with Travis and Hart holding a 30-point lead to Gregory Liefooghe and Sean Quinlan in the No. 19 Stephen Cameron Racing BMW M4 GT4,

As was the case at Sonoma Raceway, Colin Mullan will pair with Jarett Andretti in the No. 36 Andretti Autosport McLaren 570S GT4, which sits fourth in the title race.

Mullan has taken the seat of fellow Bronze-rated driver Karl Thomson, who has family commitments this weekend.

Portland, meanwhile, will see the return of Michael Dinan and the No. 21 Flying Lizard Motorsports Porsche GT4 following an injury sustained at Virginia International Raceway.

Dinan will be paired with driver coach Robby Foley, who is fresh off his first IMSA WeatherTech SportsCar Championship victory in last weekend’s race at Canadian Tire Motorsport Park.

The race will mark the first of Dinan’s three-event probation for causing the accident at VIR.

Calvert/Keegan Look to Extend SprintX Am Class Lead

Team Panoz Racing’s Preston Calvert and Matt Keegan will look to continue their lead in the SprintX Am standings.

The duo, who have claimed three class wins in the No. 51 Panoz Avezzano GT4, hold a narrow two-point lead over the No. 16 Auto Technic Racing BMW GT4 of John Allen and Kris Wilson, who are second in the class title race.

Portland will also play host Rounds 7 and 8 of GT4 West, which is currently led by ST Racing’s Harry Gottsacker and Jon Miller (Pro-Am) and Vesko Kozarov and Jeff Burton of Rearaden Racing (Am).

Teams and drivers get their first official track time starting with practice on Friday, with qualifying on Saturday and the first SprintX race set for later that day at 2:15 pm PDT.

All SprintX races will be streamed live on and via audio simulcast on SiriusXM satellite radio Ch. 383 (983 on the app).

CBS Sports Network coverage for SprintX races at Portland airs July 28 at 4 pm EDT.
