CONCORD, N.C. -- Tom Reddin has resigned as chief executive officer at Richard Petty Motorsports and Foster Gillet, son of team owner George Gillet, will oversee day-to-day operations, effective immediately.
Reddin joined RPM just prior to the start of the 2008 season, overseeing the organization's four Sprint Cup Series teams.
"This is strictly a personal decision," Reddin told ESPN.com on Friday. "When I took this job, one concern I had was how many races I'd do. I have three little ones at home."
Reddin said he'd already attended 10 races so far in 2009. For him, it was too many.
"I approached the Gillets two weeks ago and told them about my decision," said Reddin, who came to RPM from LendingTree, where he was also CEO.
The team's management had come under fire of late in the wake of poor performance and the residual frustration from its driving corps.
"Foster is coming back from Montreal, and he's going to be more hands-on at the company," said star RPM driver Kasey Kahne. "I think that it will be fine. I think Foster does a good job with things and he's a good guy to talk to and work with. Hopefully everything turns out good."
Foster Gillet said the team's performance had no bearing on the decision.
"It's safe to say ownership will take a more-active role" in the organization, he said.
