Leigh Diffey joined NBC Sports Group in 2013 as the Play-by-Play Announcer for Formula One, IndyCar and both Summer & Winter Olympics coverage.
In 2019, Leigh was the lead announcer on NBC’s first-ever broadcast of the Indianapolis 500.
Versatility is ones of his strengths and in his time at NBC Sports he has worked on the Track & Field World and National Championships, Rowing at the Rio Summer Games and Bobsled, Skeleton and Luge at both the Sochi and Pyeongchang Winter Games, the Rugby World Cup and Premiership Rugby.
NASCAR has also been a part of Leigh’s portfolio and he has called the Monster Energy Cup and Xfinity Series in addition to hosting NASCAR America.
In 2019, the IMSA WeatherTech Sportscar Championship joined NBC Sports and with Leigh’s 10-year background in the sport it was a natural fit for him to both host and commentate this series.
Prior to joining NBC, Diffey served as a Host and Play by Play for SPEED Channel in the US, the BBC in the UK and Network Ten in Australia on F1, Indycar, MotoGP, Golf (including The Masters), World Superbike, World Rally, Sailing and V8 Supercars. He was also the one of Hosts of Sports Tonight in Australia.
Diffey is a native of Brisbane, Australia, and currently lives in Connecticut with his wife and two children.
