Senior VP Robin Pemberton leaving NASCAR at end of 2015

17m - NASCAR

NASCAR Senior Vice President of Competition Robin Pemberton will leave the organization after supervising the series directors for the last 12 years, the sanctioning body announced Tuesday.

NASCAR did not immediately announce a replacement, but sources indicated former Michael Waltrip Racing competition director Scott Miller will assume that role.

The move was not a surprise as NASCAR has gone through leadership changes over the last few years that split Pemberton's responsibilities from overseeing rules as far as how the cars are built while leaving him to continue to oversee inspection and officiating.

One of his most impactful duties came on race day, where Pemberton was among the officials in the tower helping make race-day judgment calls on penalties.

Pemberton was a former crew chief for Rusty Wallace at Penske Racing as part of a career where he worked for owners Richard Petty, Jack Roush, Felix Sabates and Roger Penske.

"I'm proud of what we've been able to accomplish during my time at NASCAR," Pemberton said in a statement. "This sport has been my entire professional career and working with all the competitors and the auto manufacturers for the last 12 seasons has been a thrill.

"I feel good knowing that the work this team has done has had a positive impact on the sport. I look forward to the next challenge."
