Gordon Johncock, a two-time Indianapolis 500 winner, died Monday at his home in South Branch, Mich. He was 90. His wife, Suzanne Johncock, confirmed his death. Johncock competed in 24 Indy 500 races and finished in the top five eight times. He won the United States Auto Club title in 1976, edging Johnny Rutherford for the most points in 13 open-wheel events.

Johncock’s Indy 500 victories came in 1973 and 1982, both driving for Patrick Racing in cars sponsored by Andy Granatelli’s STP oil treatment company. The 1973 race was marred by tragedy, including the death of teammate Art Pollard in a crash during time trials and severe injuries to Salt Walther. Rain delays and additional crashes, including one involving Swede Savage, led to the race being declared over after 133 laps. Johncock was awarded first place since he led the most laps.

His 1982 victory featured a thrilling finish, with Johncock beating Rick Mears by 16-hundredths of a second, the slimmest margin in the race’s history at the time. Johncock retired from racing after the 1992 Indy 500. He was born on Aug. 5, 1936, in Hastings, Mich., and was inducted into the International Motorsports Hall of Fame in 1999 and the Motorsports Hall of Fame of America in 2002.
