(AP Photo/Terry Renna)HOMESTEAD, Fla. – NASCAR’s postseason landscape has been altered after just two Cup Series races. “The number of unique winners is really going to change how many cars get in on points, right?

Whether that’s different markets, different racetracks, it has to be different from year to year.

HOMESTEAD, Fla. Denny Hamlin found the magic at Homestead-Miami Speedway, once again. Hamlin went to the lead for the final time with 30 laps left and held off Chase Elliott for his record-tying NASCAR Cup Series victory at Homestead. At Homestead, he led 137 of 267 laps on the 1 1/2-mile track in Joe Gibbs Racing's No. Most of those fans were gone when Hamlin drove under the checkered flag at 10:46 p.m., ending the marathon day. Austin Dillon had a day hell never forget, though his seventh-place finish wasnt even close to the most significant development.
