NASCAR Xfinity Series at Texas 2017 Results: Erik Jones Takes Checkered Flag

Erik Jones led a race-high 137 laps en route to taking the checkered flag in the NASCAR Xfinity Series O'Reilly Auto Parts 300 at Texas Motor Speedway in Fort Worth, Texas, on Saturday night.

Jones beat out a pair of fellow Cup Series regulars in Ryan Blaney and Kyle Larson for the win, while Elliott Sadler was the top finisher among Xfinity Series playoff drivers in fourth place.

Here is a full rundown of the top 10 courtesy of NASCAR.com:

1. Erik Jones

2. Ryan Blaney

3. Kyle Larson

4. Elliott Sadler

5. Cole Custer

6. Christopher Bell

7. Brennan Poole

8. Matt Tifft

9. William Byron

10. Austin Dillon

Saturday's win marked Jones' third of the season in the Xfinity Series and the ninth of his young career.

With one race remaining until the cutdown to the final four playoff drivers, Sadler vaulted his way into the lead. Here is a look at where things stand with one week left in the Round of 8:

1. Elliott Sadler: Leader

2. William Byron: -5

3. Justin Allgaier: -9

4. Brennan Poole: -24

5. Matt Tifft: -29

6. Cole Custer: -37

7. Daniel Hemric: -42

8. Ryan Reed: -57

Although seven of the eight playoff drivers finished 14th or better, none of them were able to pose much of a challenge to Jones, who won all three stages.

With the exception of a 34-lap run-up front for Blaney and a 17-lap stint in the lead for William Byron, Jones rarely left the catbird seat Saturday night.

While the race was essentially a tuneup for Jones ahead of Sunday's Cup Series race, it was hugely important for those in the playoff hunt, including Ryan Reed.

As seen in the following tweet courtesy of NASCAR Xfinity, however, Reed dealt with some severe tire rub that knocked him out of contention:

Reed finished worst among the playoff drivers in 23rd, and he has an uphill climb in next week's race to advance to the final round.

Jones and Blaney took a minor risk on their final pit stops by only taking fuel, which left them susceptible to cars with fresh tires.

They were so dominant throughout the race, though, that nobody was able to truly step up to challenge them, and Jones closed out his remarkable effort with a win.

Although he is still in search of his first Cup Series win, Jones didn't hesitate to celebrate the triumph in grand fashion:

Sadler didn't win Saturday's race, but his fourth-place finish was nearly as good as a win in the grand scheme of things.

It allowed him to move into first place in the playoff standings, and barring a catastrophe next week, it likely earned him a spot in the final round as well.

Sadler sounded pleased with his showing after the race:

Since Sadler, Byron and Allgaier have been the class of Xfinity among regulars this season, it comes as little surprise that they occupy the top three spots with just two races remaining.

The most intrigue lies in the fourth spot, which seems likely to come down to Poole and Tifft next weekend.
