Almirola started the year with Greg Erwin and then worked with Ford before switching to Parrott with 10 races left in the season. He has seven top-20 finishes in his last nine races after only 13 in his first 26.
"We went through some changes this season, but since being paired with Todd and this crew, I've had the most fun I've had in a Cup car," Almirola said. "I think we have a lot of things clicking right now and have a lot of momentum heading into 2013. Everyone at RPM seems to have good chemistry right now and that's a good feeling as we all prepare for 2013."
