2. Brad Keselowski: Wasn't able to score his coveted Sprint Cup win at his home track but Keselowski turned in another solid second-place performance.
Season-to-Date Driver Rating: 96.2

3. Dale Earnhardt Jr.: Rallied back from starting at the rear of the field in a backup car to finish in the top five, thanks in no small part to fuel-mileage strategy by crew chief Steve Letarte.
Season-to-Date Driver Rating: 100.6
Point Standings: Third
Previous Ranking: Fourth
4. Matt Kenseth: A flat tire ended any chance of Kenseth giving team owner Jack Roush a Michigan win.

8. Kasey Kahne: An impressive performance by Kahne and crew chief Kenny Francis, taking a damaged car from an incident with Mark Martin and Bobby Labonte to the front of the field and ultimately a third-place finish.
