Ambrose returned to the Nationwide Series at Watkins Glen in the No. 09. Ambrose dominated the race and won his 5th Nationwide victory holding off Kyle Busch in a performance reminiscent of 2009. The next day Ambrose started second and after leading some laps, came up short after a side-by-side battle with former teammate A. J. Allmendinger who beat Ambrose by 1.5 seconds after accelerating away from Ambrose on the final lap. Ambrose's crew chief Drew Blickensderfer protested the finish by saying that Allmendinger jumped the restart, but NASCAR officials and Ambrose both denied this, Ambrose saying "The restart had no influence on the outcome. We just raced and he won."
