The Miami Open, held in Miami Gardens, Florida, saw a delayed men’s final due to rain. Novak Djokovic, aiming for his seventh Miami Open title, faced 19-year-old Jakub Mensik. Rain began at 12:50 p.m., delaying the women’s doubles final as well. The women resumed play at 6:50 p.m., and Andreeva and Shnaider won in a third-set match tiebreaker. Djokovic and Mensik finally took the court at 8:37 p.m. Djokovic, already a six-time champion at the event, was looking for his 100th career title.

Toni Breidinger balancing Racing, Modeling, and Social Media Influence

Toni Breidinger is not just a rising star in NASCAR but also a model and social media influencer with millions of followers. Her entry into the sport has been unconventional, as her contract with Toyota is through its marketing department rather than its driver development program.

Breidinger believes her presence on social media allows fans to see the real her, which in turn helps bring new audiences to NASCAR. She discussed all this and more in a recent interview with Autoweek.

“I think people want to know the real you,” Breidinger said. “People watch me race on TV, (but) they get to know the real me (through social media). Hopefully, I can bring a new demographic to watch the Truck Series and to watch NASCAR. I do feel like my fan base is very international.” (via Autoweek)

Paul Doleshal, group manager of motorsports at Toyota Motor North America, emphasized Breidinger’s ability to attract attention far more than the usual motorsports audience. In his own words,

“Toni reaches outside that (motorsports) sphere and can bring that … what’s going on over there, let me go check it out kind of aspect,” (via Autoweek)

Breidinger’s background in racing began with go-karts at age nine before she stepped into stock car racing. She spent five years in the ARCA Menards Series, securing four top-five and 27 top-10 finishes in 65 races. She is now racing full-time in the NASCAR Craftsman Truck Series with TRICON Garage.
