There's only one way for a driver to make sure that they are eligible for the NASCAR's Chase for the Championship. A win all but guarantees a berth in the Chase for the Sprint Cup as 16 drivers qualify in the new format. The top 15 drivers based on wins along with the overall points leader if the points leader hasn't won or the top 16 drivers ranked by wins qualify for the Chase.

And with the season heading toward the summer months, some of NASCAR's biggest names have yet essentially to lock themselves into the Chase.

Jimmie Johnson

He has come so close a handful of times, being edged by Kurt Busch at Martinsville. He also finished third at Darlington.

Jeff Gordon

He leads the points standings and has dominated two races this season at Texas and Richmond. While he'd get into the Chase by virtue of being the points leader, he'd all but assure himself of a Chase spot with a race victory. 

Matt Kenseth

Don't look now, but the No. 20 team appears to be surging. In the past six races, Kenseth has finished sixth or better five times.

Kyle Larson

Inexperience hasn't hurt this youngster's ability to run well in 2014 in NASCAR's top division. He finished second at Fontana and fifth at Texas and appeared to be a strong contender for the win entering Richmond before damage early in the race. He also posted a top 10 at Talladega.

Greg Biffle

Some of the track's that have historically been strong for Biffle are coming up soon with events at Pocono and Michigan. He also has a strong burst of momentum in hand after a season-best finish of second at Talladega.
