Chase clinch scenarios for Indianapolis

Only seven races remain before the 16-driver Chase for the NASCAR Sprint Cup field is set. Here's what we know:

#4-Kevin Harvick, #88-Dale Earnhardt Jr. and #48-Jimmie Johnson have fulfilled two of the three Chase criteria. All three have the multiple wins that guarantee a spot among the top 16 winners, and have locked up a top 30 spot. All they need to do now is start each of the remaining races in the regular season.

A few drivers can join them this weekend. If #41-Kurt Busch leaves Indy with a 289 point lead over 31st, he will lock up a top 30 spot. #22-Joey Logano, #78-Martin Truex Jr., #2-Brad Keselowski, #20-Matt Kenseth and #11-Denny Hamlin all need to win, and in some cases get some help to lock up a top 30 spot (leaving Indy with a 289 point lead over 31st).
