Brooklyn, MI (My Sportsbook) - Series: NASCAR Sprint Cup. Date: Sunday, August 15. Race: CARFAX 400. Site: Michigan International Speedway. Track: two-mile oval. Start time: 1:00 p.m. (et). Laps: 200. Miles: 400. 2009 winner: Brian Vickers. Television: ESPN. Radio: Motor Racing Network (MRN)/SIRIUS NASCAR Radio.

With four races remaining before the Chase begins, tension is building among several drivers who hope to secure a spot in the playoffs. Just 205 points separate 12th-place Mark Martin from 19th-place Juan Pablo Montoya, who won his second career Sprint Cup race last weekend at Watkins Glen International.

Montoya made the Chase for the first time last year, finishing eighth in points. He is a long-shot in making the playoffs for the second year in a row, but anything can happen between this weekend's race at Michigan and next month's regular-season finale at Richmond.

"I think it's been for a while realistic that to make it you need a miracle," Montoya said. "Win one week, lose another. I made a lot of mistakes this year. I hurt the team a lot from that point."

Montoya snapped a 113-race winless streak in NASCAR's top-tier series at Watkins Glen. His first win came in June 2007 at the road course in Sonoma, CA. Montoya's win at Watkins Glen allowed him to gain two position in the standings.

"I think last year we didn't have the pace we have this year, and we made the Chase pretty easy, I thought," Montoya added. "This year, we had two cars capable, easily making the Chase, and both cars are out. That's what it is, I guess."

The closest battle in the "Race to the Chase" right now is between Martin and 13th-place Clint Bowyer.

After finishing 32nd at Watkins Glen, Bowyer dropped out of the top-12, as he trails Martin by a slim 10 points. Martin moved up one spot in the standings after his 19th-place run.

"This team is improving every week, and we just have to keep that going in Michigan," Martin said. "It's a good feeling to be back in there (top-12), but it's not at all a relief. We have four races to go. Anything can happen."

Martin won at Michigan in June 2009.

Bowyer's Richard Childress Racing teammates Kevin Harvick and Jeff Burton are first and third in points, respectively. Harvick could become the first driver to clinch a spot in the Chase this year, as he currently is 569 points ahead of Martin.

Ryan Newman, Kasey Kahne and Montoya are those drivers who made last year's Chase, but presently sit outside of the top-12. Newman is 83 points behind Martin in the 14th spot.

"It's still a great race for that 12th spot," Newman said. "I think it's easy to see that with all the shifting in the points each week. While we would much rather be inside the top-12 already, we've put ourselves in a good position to make the Chase, thanks to a lot of hard work by everyone at Stewart-Haas Racing."

Jamie McMurray, winner of the Daytona 500 and the Brickyard 400 this year, is 94 points in back of the 12th position. McMurray jumped from 17th to 15th after an impressive sixth-place run at Watkins Glen.

Dale Earnhardt Jr. sat in 11th place after last month's race at Daytona, but has fallen to 16th with finishes of 23rd of worse in the last four races. Earnhardt Jr.'s last win in the series came in June 2008 at Michigan (79 races ago).

Could Sunday be the day Earnhardt Jr. finally snaps his winless streak?

"[Crew chief] Lance [McGrew] and the guys unloaded a great car last time at Michigan," said Earnhardt Jr., who finished seventh at Michigan two months ago. "We've had some good runs with this car. I enjoy going to Michigan because it's so wide. It has a lot of different grooves, and we can move around and find places to run on the track. We like coming here because it's in the backyard of the manufacturers. Hopefully, we'll get a win for Chevrolet."

Kasey Kahne heads to Michigan 133 points behind Martin, while David Reutimann trails by 166 markers.

Earlier this week, Red Bull Racing announced that Kahne will drive one of their Sprint Cup cars next year. Kahne will then move over to Hendrick Motorsports in 2012 to drive Martin's No.5 car.

Up until the 2009 season, Roush Fenway Racing had been dominant at Michigan, winning a Cup race there for seven consecutive years. Team owner Jack Roush, who resides 60 miles away from the two-mile track in Northville, MI, recorded his 11th victory there with driver Carl Edwards in August 2008. Roush moved into a tie with the Wood Brothers for most car owner wins at the track.

Roush remains at the Mayo Clinic in Rochester, MN after suffering facial injuries during a plane crash two weeks ago in Oshkosh, WI. His condition was upgraded to fair last week, but his release date from the hospital remains undetermined.

Last week at Pocono, Greg Biffle gave Roush and manufacturer Ford its first Cup victory of the 2010 season. Biffle presently occupies the 11th position, but holds a comfortable 112-point advantage over Martin.

"We know we are in the fight of our life to get in the Chase right now," Biffle said. "We have Michigan, Atlanta and Bristol all coming up, and those are some great racetracks for us that are right down our alley."

Biffle won back-to-back races at Michigan from August 2004 to June 2005.

Forty-seven teams are on the preliminary entry list for the CARFAX 400.
