Milo Ventimiglia to wave green flag as Indianapolis 500 honorary starter

"This Is Us" actor Milo Ventimiglia will serve as the honorary starter for Sunday's Indianapolis 500.

Ventimiglia will wave the green flag and start the 105th running of the race. Ventimiglia plays family patriarch Jack Pearson on the show and is a three-time Emmy nominee for best actor.

"Milo's passion for racing and speed make him the perfect choice for this exciting Race Day honor," IMS president Doug Boles said.

Ventimiglia's "This Is Us" co-star Justin Hartley, who plays Kevin, served as the honorary starter for the 2019 IndyCar Grand Prix on the road course at Indianapolis Motor Speedway.

Former IndyCar and NASCAR driver Danica Patrick will lead the field to green Sunday as the honorary pace car driver, while country recording artist Jimmie Allen will perform the national anthem before the race.
