Since making his debut in the Porsche Deluxe Carrera Cup North America last year, Jeff Mosing contested 14 races in the Rafa Racing Club Pro-Am class without standing on the top step of the podium.

That was until he arrived at Watkins Glen International last weekend. The Topp Racing driver not only scored his first win on Friday but backed that up with another success in Saturday’s race to not only win but also take the extra point for the fastest lap of the race.

The result didn’t come easy either. Mosing had to catch and pass 2021 class champion and last year’s runner-up Efrin Castro in both races to win.

That performance has elevated him to third in the Pro-Am class points and Topp Racing to sixth overall in the team’s championship.

A long-time competitor in various IMSA championships, the Austin, TX-based racer is also no stranger to success in Porsche machinery. He won a pair of races in the Continental Tires Sports Car Challenge in 2014 aboard a Porsche Cayman and earned a championship in Porsche GT3 Cup Challenge USA in the Gold class by taking nine wins from 16 races – also with Topp Racing.

At the halfway point of the 2023 Porsche Deluxe Carrera Cup North America championship, the Rafa Racing Club Pro-Am class certainly appears to be heating up, with five different drivers taking wins so far.

Alongside Mosing, other winners have included Castro, Marco Cirone, Moisey Uretsky, and last year’s champion, Alan Metni.

“ I’m so grateful and fortunate to have such a great team, and they really had the setup nailed this weekend,” Mosing said.

“It made me look like a hero, but Castro ran me hard, but I was very fortunate not to have any pressure from behind, so I could just focus on him and aim to make a run in the last part of the race on Saturday.

“But he ended up having a little bobble into turn one, and that just gave me the opportunity to get past.

“Historically, I’ve just absolutely loved this series. I still have my original Cup Car from 2010. These cars are so amazing. Porsche makes a great product – it’s bulletproof.

“The way we beat these cars up over all the bumps and everything, it’s just amazing what they can take, and I’m really looking forward to running the rest of the series this year and hopefully next year too.”
