Penske plans to keep Hornish in 2013:

in part from a Penske Racing Media Teleconference featuring Joey Logano and Tim Cindric:
It was announced yesterday that Joey Logano will join the Penske Racing organization in 2013 as he will begin a multi-year agreement to drive the #22 Shell-Pennzoil Ford in the NASCAR Sprint Cup Series. Joey will join Brad Keselowski and the #2 Miller Lite Ford team to form a potent Cup Series combination for Penske Racing next season. One of the media questions for Penske Racing president Tim Cindric was about the future of Sam Hornish Jr., currently the full-time driver for Penske Racing in the Nationwide Series and in the #22 Sprint Cup Series ride.
Q.) Tim, where does this leave Sam (Hornish Jr.) with Penske Racing and plans for the future?
TIM CINDRIC: Obviously Sam has done a great job for us, picking up where we needed to go from Daytona onwards. I think we continue to see him grow in his abilities as a Cup driver, working with (crew chief) Todd Gordon and the guys. I think you saw that this weekend at Atlanta. I think we ‘ll continue to move that forward. He’s going to continue to drive the 22 car for the remainder of the year. We ‘ve continued to work on putting a Cup program together for Sam; we just haven ‘t been able to close that process yet. I foresee Sam driving for us a full season Nationwide next year and hopefully some Cup races, as well.
Q.) Sam’s future, is it possible you could put together a third Sprint Cup car for him next year?
TIM CINDRIC: That would certainly be our first preference, a third full-time Cup car. It’s pretty late in the season. The potential we had for that in terms of sponsorship, they haven ‘t come to fruition yet. I think you ‘ll see him in a couple (Cup) races for sure. We haven ‘t been able to build on that. We haven ‘t been able to get more than a couple races at this time. As far as a full season Nationwide, that’s what I envision happening for sure.(Penske Racing Media Conference)(9-6-2012)
