NASCAR Power Rankings: Did historic Kansas finish shake things up?

Kyle Larson certainly isn't going to lose his top spot in the rankings after his performance last week as he won the closest finish in NASCAR history by 0.001 seconds over Chris Buescher.

The Hendrick Motorsports driver needed a late caution after wearing out his tires on the previous run. He got it just in time to be able to get fresh tires and make the winning moves.

The NASCAR season is one-third complete (12 out of 36 events). Here's a look at my current power rankings and how their last six races compared to their first six races of the year.

1. Kyle Larson (Last Week: 1)

Larson has earned 262 points — more than any other driver — in the last six races as he has moved from fifth to first in the Cup standings. He didn't do that with wins as he has two victories this year, but he has won four stages in the last six races.

2. Denny Hamlin (LW: 3)

Hamlin ranks fourth in the last six races with 205 points. The Joe Gibbs Racing driver is a model of consistency — he earned 206 points over the first six races.

3. Martin Truex Jr . (LW: 4)

Truex ranks third with 218 points over the last six races and just like his JGR teammate Hamlin, he is certainly consistent. He was leading the points after the first six races this year with 220 points.

4. Chase Elliott (LW: 5)

Elliott continues to surge as he has 249 points in the last six races compared with 173 over the first six. Elliott has climbed to third in the overall Cup standings as the Hendrick driver has five top-5 finishes in his last six races.

Byron has three wins this year and had
