"Never, ever give up," Keselowski said. "Never give up. This team doesn't and we didn't today. You get a good run like we did and that is a product of that effort. I thought we had some really good speed there at the end. I almost wanted another yellow to race the 5 and the 20. Matt (Kenseth) did a great job executing the restarts really well. We were so close."

Carl Edwards finished fifth, Johnson was sixth, the No. 88 of Dale Earnhardt Jr. was seventh, Martin Truex Jr. finished eighth, Kevin Harvick ninth and Paul Menard rounded out the top 10.
