Spire Motorsports is preparing for a milestone event as the NASCAR CRAFTSMAN Truck Series heads to the streets of St. Petersburg, Florida, for its first-ever street-course race—the OnlyBulls Green Flag 150. Set for Saturday, February 28, and broadcast live on FOX, this Spire Motorsports race advance showcases the team’s readiness, resilience, and history as they tackle uncharted territory in the third points-paying round of 2026.
NASCAR’s First Truck Series Street Race: Spire Motorsports at the Forefront
The Grand Prix of St. Petersburg brings a new challenge for the NASCAR CRAFTSMAN Truck Series, featuring a 1.8-mile, 14-turn street circuit never before seen in the series’ 18 previous road course events. Spire Motorsports has enjoyed notable success on road courses, claiming three top-five and four top-10 finishes in prior outings, setting the stage for this inaugural street-circuit competition.
Saturday’s OnlyBulls Green Flag 150 marks a significant expansion for both NASCAR and Spire Motorsports, kicking off the first of two scheduled street-race events on the 2026 calendar. Spire’s drivers and teams look to leverage past experiences while adapting to a format that rewards both precision and boldness given the track’s unique risks and opportunities.
Connor Mosack’s Return with the No. 7 Friends of Jaclyn Chevrolet
Connor Mosack is set to race the No. 7 Friends of Jaclyn Chevrolet Silverado RST, making his first of twelve scheduled starts with Spire Motorsports in 2026. Mosack will be joining the field on this demanding street course, drawing on an extensive background in both truck and road racing disciplines.
In 2024, Mosack participated in six Truck Series races for Spire, achieving a third-place result at Homestead-Miami Speedway and notching one top-five and four top-10 finishes. His series record stands at one pole, one top-five, and eight top-10 finishes over 36 starts. On road courses, his experience includes a recent top-ten at Charlotte Motor Speedway ROVAL in October 2025.
Beyond trucks, Mosack has proven adept at road racing, recording fifth-place results at both Watkins Glen International and the Charlotte ROVAL in the NASCAR O’Reilly Auto Parts Series. His success extends to the Trans Am CUBE 3 Architecture TA2 Series, where victories at Watkins Glen in 2021 and 2022 highlight a career that includes nine podiums, six poles, and consistent top-point finishes. This mix of high-level road course experience positions him well for the sharp turns and close walls of St. Pete.
The Friends of Jaclyn Foundation, prominently displayed on Mosack’s truck, works to improve life for children facing pediatric brain tumors and cancers, with programs such as Adopt-A-Child and Guardian Angel. This collaboration underscores Spire’s values both on and off the track.
This weekend, Mosack will use Spire’s chassis SMT-071, which boasts a strong resume: two poles, one win, and six top-fives across ten starts. Kyle Busch previously drove this chassis to victory at Sonoma in 2022, while Connor Zilisch piloted it to a fifth-place run at Charlotte ROVAL last fall. Whether in Spire hands or as former property of Kyle Busch Motorsports, SMT-071 has proven dependable and fast on technical circuits.
Mosack Offers Insight on the Unique Street Circuit Test Ahead
Connor Mosack’s anticipation for the challenge of St. Petersburg is palpable. When asked about tackling this tight street course in a NASCAR truck, Mosack responded:
“St. Petersburg seems like it has some high-speed, high-risk corners that are really tight. I think a lot of guys will probably get into trouble there. And something that’s unique about the trucks and street courses is how sensitive the fenders and bodies are. Any kind of small mistake where you kiss the fence a little bit, or make contact with other trucks, it can really harm your day, cut a tire down or hurt the down force. It’s going to be easy to make a lot of mistake but, it looks like a fun, tight street course so I am looking forward to it.”

Brian Pattie Directs Mosack’s Efforts for the No. 7 Team
Veteran crew chief Brian Pattie will be calling the shots for Connor Mosack’s twelve-race schedule in 2026. Pattie’s leadership pedigree is formidable: he recently led Kyle Busch to his 68th NASCAR Truck Series victory at Atlanta, where the Spire team celebrated its 10th series win. Pattie’s expertise extends to the NASCAR Cup Series, where he claimed road course victories as crew chief for Juan Pablo Montoya at Watkins Glen in 2010 and Clint Bowyer at Sonoma in 2012.
Pattie’s seasoned perspective, developed over a 25-year NASCAR career, includes six Cup Series wins and eleven victories in the O’Reilly Auto Parts Series. His tactical acumen will be critical in navigating the unpredictable elements of street racing, supporting Mosack’s debut at St. Pete.
James Hinchcliffe Brings IndyCar Experience to the No. 77 Delaware Life Chevrolet
James Hinchcliffe is poised for double duty at St. Petersburg, taking the wheel of the No. 77 Delaware Life Chevrolet Silverado RST in the Truck Series debut at the street circuit, while also handling FOX broadcast duties during Sunday’s Firestone Grand Prix of St. Petersburg for the NTT INDYCAR Series. Hinchcliffe is a proven winner at this venue, claiming victory at the 2013 INDYCAR Honda Grand Prix of St. Petersburg after leading the final 26 laps.
A six-time INDYCAR winner and 2011 Rookie of the Year, Hinchcliffe logged ten starts on these very streets, achieving three top-five and five top-10 finishes. His career features 161 starts, 18 podiums, and two INDYCAR Fan Favorite Awards—honors that reflect both his driving talent and his engaging personality. His shift to broadcast in 2022, and later as part of the F1 TV team, builds on this multifaceted motorsports career.
Hinchcliffe’s No. 77 truck carries backing from Delaware Life, an insurance and annuity provider committed to empowering financial professionals and their clients with flexible planning options. The No. 77 will utilize chassis SMT-072, which has three top-five and six top-10 finishes over ten starts—most recently driven to a fourth place by Rajah Caruth at Charlotte last October. The proven performance of this chassis brings added confidence to Hinchcliffe’s NASCAR debut.
Hinchcliffe Reflects on Adapting to NASCAR from INDYCAR
When asked about translating his street circuit expertise to the NASCAR Truck Series, Hinchcliffe stated:
“Well, given the nature of any street circuit, with the walls so close and huge penalties for making mistakes, any track knowledge is an advantage. That said, I don’t know anything about racing a truck, so what I have in circuit knowledge, the series regulars have in truck knowledge. It will be interesting to see how that translates to performance.”

Addressing his biggest challenges making the switch, he added:
“Pretty much everything. Having a roof, sitting on the left, an H-pattern gearbox…short of the fact it has four tires, an engine and a steering wheel, there really isn’t much that translates from an INDYCAR. While the adjustment is big, I’ve got to thank Spire Motorsports so much for all the effort in preparing me as best they can for my first race. It’s already been a huge team effort and I’m excited to see how it plays out.”

Chad Walter’s Guidance Behind the No. 77 Team’s Efforts
Chad Walter returns atop the pit box for the No. 77 team, overseeing a lineup of all-star drivers for Spire Motorsports in the 2026 Truck Series. Walter’s strategic play recently powered Carson Hocevar and the No. 77 entry to a runner-up finish at Atlanta despite overcoming early adversity—a pivotal contribution to the team’s first one-two result of the year.
Walter’s background offers specific strengths for road and street courses, highlighted by a win with Ron Fellows in the 2008 O’Reilly Auto Parts Series race at Circuit Gilles Villeneuve. Across 19 road course starts, he’s earned a win, five top-fives, and seven top-10s; overall, Walter’s tally includes six victories, 55 top-fives, and 139 top-10s across the O’Reilly and Truck Series. The Cornell University mechanical engineering graduate combines technical knowledge with on-track racing insight, assets that will be vital on the St. Petersburg circuit’s unforgiving layout.
