During the Bommarito Automotive Group 500 at World Wide Technology Raceway in Madison, Illinois, IndyCar rookie Louis Foster delivered a humorous Father’s Day message to his teammate Graham Rahal. The timing of the race, held on Father’s Day, prompted many drivers from IndyCar and its junior series Indy NXT to share personal stories and wishes in celebration of the day.
While most drivers offered heartfelt tributes to their own fathers and fathers worldwide, Foster instead directed a playful greeting to Rahal, whom he affectionately calls his ‘paddock dad‘ and teammate at Rahal Letterman Lanigan Racing (RLL).
“I wanna wish a very happy Father’s Day to my paddock dad Graham Rahal. He’s been a great guy to me all year. One day, maybe he’ll be my surrogate father, who knows?” the 21-year-old said via IndyCar on X. [1:07 onwards]
This nickname is not new for Foster. After the season opener in St. Petersburg, he referred to Rahal as the ‘team dad,’ emphasizing the veteran’s role as a mentor within the squad.
“Graham [Rahal’s] been the team dad, to be honest. So, its been great. Graham’s a really great dude. He knows a lot about IndyCar racing, I mean, he led his first IndyCar race when I was about four years old, so he’s been around a lot…He’s really good with getting the best out of people,” Foster had said on the Pit Pass Indy podcast.
Rookie Foster’s Season So Far and Race Day Grid Positions at WWTR
Louis Foster has shown promising but inconsistent performances in his rookie IndyCar season. His two strongest results to date were an 11th-place finish at the Indianapolis Motor Speedway (IMS) road course and 12th place at the 109th Indianapolis 500. Both results demonstrated his ability to compete in challenging events.
For the Bommarito Automotive Group 500 on June 15, Foster qualified to start in 21st position on the 1.25-mile oval at World Wide Technology Raceway, with teammate Graham Rahal just behind him in 22nd. Rahal, a seasoned driver, faced a tough qualifying session, struggling particularly with understeer in the final corners of the circuit, which affected his two-lap time.

The third RLL driver, Devlin DeFrancesco, will lead the team from 17th on the grid as they aim for a strong race performance despite being mid-pack starters.
Veteran Graham Rahal’s Heartfelt Father’s Day Message to His Family
Beyond his IndyCar duties, Graham Rahal took a moment on Father’s Day to express his deep affection for his family. Rahal, who is a father to two daughters, Tinley and Harlan, shared a touching message reflecting on the joy of fatherhood and anticipation for the arrival of their third child this fall with wife Courtney Force.
“Undoubtedly, the best part of life. There is nothing like being a dad and feeling that daddy daughter bond everyday. Love my girls, miss them today, and excited for #3 to join us this fall. Happy Fathers Day to all the great dads out there #GirlDad #FathersDay.”
Despite Rahal’s low starting position at 22nd, he remains optimistic about the race. Acknowledging the car’s lack of speed during qualifying and the challenges encountered with handling, Rahal and the RLL team will no doubt work diligently to improve their performance during Sunday’s event.
The Significance of Foster’s Bond with Rahal and Team Dynamics
Louis Foster’s light-hearted “Father’s Day” comments underscore the mentor-mentee dynamic within Rahal Letterman Lanigan Racing. Rahal’s experience and leadership foster a supportive environment that helps rookies like Foster learn and improve throughout the demanding IndyCar season.
As Foster builds his reputation in top-level open-wheel racing with his promising displays at challenging events such as the Indy 500 and IMS road course, the camaraderie with veterans like Rahal will be crucial to his growth. Their close relationship, visible in moments like the Father’s Day shoutout, reveals the team‘s strong internal culture and supportive atmosphere.
This positive team spirit, combined with continued development of car performance, will play a key role as they aim for better results in upcoming races throughout the IndyCar calendar.
