Steven Patrick “Steve” Byrnes was born on April 14, 1959 in Chicago, Illinois and raised in New Carrollton, Maryland. He was the eldest of five siblings. He graduated from Largo High School in 1977, where he was a quarterback on the football team and pitcher on the baseball team, and from the University of Maryland in 1981. As a senior, he served as an intern for WJLA in nearby Washington.

Byrnes began his television career shortly after graduating college. He was first hired as a weekend sports producer where he covered the Washington Redskins, Washington Bullets, Maryland, Georgetown, the Baltimore Orioles, and other sports. In November 1982, he had his first opportunity to be an on-air personality, when he was hired at Sullivan’s Island, South Carolina-based WCIV. While employed there he was a sports reporter and weekend anchor for the NBC affiliate until January 1985.

From 2001 until 2014, he was a pit reporter for Fox NASCAR. He also served as a fill-in studio host and lap-by-lap announcer whenever Chris Myers or Mike Joy, respectively, were not available. From 2001-03 he also served as host of Totally NASCAR on Fox Sports Net, earning a Sports Emmy nomination for best daily studio show in 2002. As of 2014, Byrnes was the co-host of NASCAR Race Hub on Fox Sports 1 and was expected to be the lead announcer for the Camping World Truck Series in 2015.

Afterward, Sunbelt Video hired him, in which he hosted the NASCAR newsmagazine Inside Winston Cup with Ned Jarrett, which marked the beginning of producing and hosting NASCAR segments. He announced what was happening on pit road for World Sports Enterprises, and later worked for TBS, TNN (now Paramount Network) and CBS. He was a backup pit commentator for Monster Jam on TNN. In 2006, he was given an extra assignment as one of the network’s available play-by-play broadcasters for Fox’s NFL broadcasts, joining Bill Maas for selected games when Fox had seven or eight games in a given week.

In late August 2013, Byrnes was diagnosed with an early stage of head and neck cancer. After chemotherapy for the rest of the year, Byrnes was deemed cancer-free in early 2014. However, later that year in September, he was diagnosed with a recurrence of stage 4 head and neck cancer; on October 9, Fox Sports announced that he had decided to take an indefinite leave of absence from work in order to focus on his treatment.

On April 10, 2015, it was announced that, in coordination with Bristol Motor Speedway, Fox, and Stand Up to Cancer, the 2015 Food City 500 would be renamed the Food City 500 In Support Of Steve Byrnes and Stand Up To Cancer; the race would feature tributes to his legacy as a NASCAR broadcaster, along with his 56th birthday, which fell during the week prior to the race.

Two days after the tribute race, Byrnes died early on April 21, 2015 of complications from his cancer in Fort Mill, South Carolina, just a week after turning 56, and was survived by his wife Karen and son Bryson. In tribute, drivers Josh Wise and Clint Bowyer added photos of Byrnes and his son Bryson to their cars’ hoods for the Toyota Owners 400. After Byrnes was invited to become part of the voting panel for the NASCAR Hall of Fame Class of 2016, Bryson delivered his father’s completed ballot to the accountants that tally the votes on May 20, 2015, completing Steve’s final duties.
