Elledge, Pemberton swap roles at Red Bull Racing

Red Bull Racing Team officials announced Wednesday the swap of crew chiefs and supporting personnel between the Nos. 82 and 83 cars, effective immediately.

"Due to the circumstances of our current situation, we have an opportunity to experiment with different personnel combinations," said Jay Frye, Red Bull Racing general manager and vice President.

Scott Speed, driver of the No. 82 will now be paired with crew chief Ryan Pemberton, and Casey Mears, driver of the No. 83 in regular driver Brian Vickers' absence will be with crew chief Jimmy Elledge, who previously worked with Mears at Chip Ganassi Racing from 2003-2005, earning two poles, four top-fives and 18 top-10 finishes.

Speed is currently in his second full-time season with Red Bull and has improved tremendously. At this point last year, Speed was 35th in points with two DNQs and three DNFs. This season, he is 26th in points with one top-10 finish, a 10th at Atlanta, he has led in four events and been running at the finish in all 13 starts.

Mears took control of the No. 83 at Dover when Vickers was diagnosed with blood clots and was advised by doctors to miss up to six months while he was on blood-thinning medication. In Mears' two starts, he finished 22nd at Dover and 29th at Charlotte.
