'''Leigh Robert Diffey''' (born 3 March 1971) is an Australian-American [[auto racing]] and [[track and field]] commentator. He is best known for being the lead play-by-play announcer for much of [[NBC Sports]]' motorsports coverage, currently calling [[NASCAR Cup Series]], [[IMSA]] sports car races for the network and AMA Supercross. Before this, he was the lead voice of NBC's [[Formula One]] and [[IndyCar Series]] coverage. Diffey has also worked play-by-play for NBC's coverage of the Summer and Winter [[Olympic Games]], most notably becoming the network's lead track and field sportscaster prior to the [[2020 Summer Olympics]] in Tokyo.

Diffey's broadcasting career began by calling motorcycle races in his home country. His career has included stints with [[Network Ten]] in Australia and the [[BBC]] in the United Kingdom covering various forms of motorsport. In the United States, Diffey joined [[Speed (TV network)|Speed Channel]] in 2003 before moving to NBC when Formula One's US television rights were transferred to the network in 2013.
