Time running low for winless drivers as Chase draws near (AP) — With time running out on his bid to make the Chase for the Sprint Cup, Greg Biffle is back at the site of his most recent victory. Biffle is the active leader in wins at Michigan, but he finished 19th at the track earlier this season. For whatever reason we haven't been able to get them both dialed in together. Since his last win in 2013, Biffle has finished in the top 10 twice in six races at Michigan. Each end is different, and what I like about the race track is no matter how your car is driving, you can adjust your line around the race track, Biffle said.
