Leigh Diffey, veteran analyst Calvin Fish and former Monster Energy NASCAR Cup Series driver A.J. Allmendinger will lead NBC Sports’ broadcast team for the IMSA WeatherTech SportsCar Championship season.
Diffey, Allmendinger, and Fish will make their IMSA broadcast debut for NBC Sports at the Rolex 24 at Daytona, kicking off more than 100 hours of IMSA programming set to air across its platforms this year.
Additional details regarding analysts and pit crew reporters will be announced at a later date.
“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.
Diffey called both the Grand-Am Rolex SportsCar Series and American Le Mans Series from 2003-12, prior to his arrival at the network.
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.
As part of a six-year partnership announced in April, NBC Sports will present 12 races across NBC, NBCSN, CNBC, NBCSports.com and the NBC Sports app throughout 2019.
Race highlights include the 12 Hours of Sebring on March 16; the Grand Prix of Long Beach on April 13 and the penultimate race of the season from WeatherTech Raceway Laguna Seca on Sept. 15.
