The track went green on Lap 111, Kahne slowing with suspension problems, specifically a broken sway bar joint.

Mike Wallace, Justin Allgaier and McDowell crashed on the backstretch on Lap 120, the track going yellow again. But once again, when the track went green on Lap 129, it was all Busch.

At Lap 150, Busch led Harvick by 4.825 seconds, with Keselowski, Bliss and Kenseth completing the top five. Three laps later, a flat left-rear tire sent Joey Logano hard into the wall at the entrance to Turn 3.

That sent the leaders down pit road on Lap 155 for what was expected to be the final pit stop. Busch led the field off pit road, followed by Keselowski, Kenseth, Leffler and Harvick.

Keselowski got a terrible restart on Lap 159, allowing Busch to break away to a huge lead. Shortly thereafter, Brendan Gaughan tagged the wall to bring out a debris caution on Lap 167.

Busch led again on the Lap 172 restart, ahead of Kenseth and Leffler. The track would stay green for just six laps, before Steven Wallace and Michael Annett crashed while racing for 17th place.

Under caution, the top nine cars stayed out, while the cars in positions 10-15 all came in for tires. The green flew on Lap 186, Busch leading Leffler, Mears, Keselowski and Bliss.

This time it was Leffler who stumbled a little on the restart, once again allowing Busch to build a lead, which he would never surrender.
