For 2011 Daytona 500 winner Trevor Bayne, the announcement of Good Sam/Camping World's sponsorship of the No. 21 Wood Brothers Ford represents both welcome news and unfinished business.

Wood Brothers Racing announced Saturday that Good Sam/Camping World will sponsor Bayne in four races this season, expanding Bayne's Sprint Cup schedule from 12 to 16 races. Bayne will race under Good Sam/Camping World colors in the May 19 Sprint All-Star Race at Charlotte and in Cup points races at Atlanta (Sept. 2), Chicago (Sept. 16) and Charlotte (Oct. 13).

Bayne has run three Cup races this season, with a best finish of ninth at Las Vegas. He started the first five Nationwide Series races of the season in Roush Fenway Racing's No. 60 Ford, but a lack of sponsorship curtailed his participation after that.

Bayne was supposed to run the All-Star Race with Good Sam/Camping World last year, but an illness believed to have resulted from a tick bite kept him out of action in May.

"I wound up in the hospital and was really bummed about that," Bayne said.
