NBC Sports announced that the commentator team for its inaugural season of IMSA sporrts car racing coverage will be led by play-by-play voice Leigh Diffey, alongside a pair of former racers — NASCAR and IndyCar veteran A.J. Allmendinger and IMSA GT vet Calvin Fish as analysts. Additional details regarding analysts and pit crew reporters will be announced at a later date, the network said.
“Leigh has a unique ability to communicate all of the stories and battles taking place throughout a race,” said Sam Flood, Executive Producer and President of Production, NBC Sports. “A.J. will bring a fresh perspective from the driver’s seat to the booth, while Calvin’s familiarity with IMSA both as a racer and analyst will combine for an informed and entertaining listen.”
Since joining NBC Sports in 2013, Diffey has served as the lead play-by-play voice for the network’s IndyCar and Formula 1 coverage. Prior to joining NBC Sports, Diffey called both Grand-Am Rolex SportsCar Series and American Le Mans Series races from 2003-12.
Fish previously served as an analyst on FOX Sports’ IMSA coverage, and was IMSA’s GTO class winner at the 12 Hours of Sebring and Rolex 24 at Daytona in 1990.
Allmendinger joined NBC Sports after competing in NASCAR for 13 seasons, most recently driving JTG Daugherty Racing’s No. 47 Chevy in the Monster Energy NASCAR Cup Series. In 2012, Allmendinger was part of the overall-winning team in the Rolex 24 At Daytona.
Diffey, Allmendinger, and Fish will make their IMSA broadcast debut for NBC Sports from the 57th running of the Rolex 24, as part of more than 100 hours of IMSA programming set to air across NBC Sports’ platforms in 2019.
In all, NBC Sports will present 12 races across NBC, NBCSN, CNBC, NBCSports.com and the NBC Sports app throughout the year.
