Newman grabbed his series-leading fifth victory of the year, stretching his final tank of gas 52 laps on the 2-mile oval at Michigan International Speedway to win the GFS Marketplace 400 on Sunday.

Busch came up a lap short and wound up 18th.

"I heard (Busch) was going to be pushing his luck more than we were," Newman said. "We were close. It will be interesting to see what's left (in the gas tank)."

Matt Borland, Newman's crew chief on the No. 12 Penske Racing South Dodge, said, "Ryan saved quite a bit of fuel there at the end. He's real good at that and still carrying a lot of speed.

"With four laps to go, we just told him to go for it and we'll see what happens." More
