Richard Petty Motorsports plans to run full season with Sam Hornish Jr. despite open inventory

Sam Hornish Jr. is finally back in the Sprint Cup Series after a four-year absence, in a ride Richard Petty Motorsports insists it is committed to fielding for the entire year.

RPM has 26 unsponsored races as it heads into next month's season-opener. Twisted Tea will sponsor the Daytona 500 and the July race at Daytona International Raceway, and team co-owner Andrew Murstein is willing to provide some funding through his Medallion Bank.

RPM director of operations Sammy Johns said he's moving forward as if the organization will have two full-time cars all season.

RPM recently hired 35 employees and moved into its former shop in Mooresville.

Hornish is replacing Marcos Ambrose in the No. 9 Ford. His last full-time season in Cup was in 2010.
