Michigan Chase Clinch Scenarios:

#88-Dale Earnhardt Jr., #2-Brad Keselowski, #24-Jeff Gordon, #48-Jimmie Johnson, #99-Carl Edwards, #22-Joey Logano and #4-Kevin Harvick have clinched a spot in the Chase for the NASCAR Sprint Cup, assuming they attempt to qualify for the remaining four races.
If there is a repeat 2014 winner in the Pure Michigan 400 at Michigan International Speedway, any driver with one win and a locked-up top 30 spot will clinch a spot in the Chase. Potentials: #18-Kyle Busch, #11-Denny Hamlin, #43-Aric Almirola, #41-Kurt Busch and #47-AJ Allmendinger. To clinch a top 30 spot, the clinching driver must be 145 points ahead of 31st place leaving Michigan.
If there is a new winner, one-win drivers could potentially clinch a spot. But there would still be the potential for 16 different winners, and a winless points leader ‘” meaning a winner would be bounced from the Chase. So there are no guarantees here.
Because he is so high in the points, if #20-Matt Kenseth wins, he would clinch a spot, even though it would be his first win. Other high-ranking winless drivers could potentially clinch with a win and help.(NASCAR)(8-15-2014)
