Kyle Busch claims second straight NASCAR Sprint Cup win at Texas

The Joe Gibbs Racing Toyota driver took advantage of Furniture Row's Martin Truex Jr decision to not to pit for tyres at the final caution and consequently powered by on the outside to take an unlikely win to add to his Xfinity victory the night before.

The race was delayed by rain for two hours and Truex looked the more likely to secure the win, leading leading 141 of the 334 laps and trading the lead with polesitter Carl Edwards for the majority of the race.

The two proved to be in a class of their own, but a botched pitstop by JGR dropped Edwards a lap down before he recovered to finish seventh via a free pass.

Truex still looked the man to beat in the final stages but the decision not to pit for fresh tyres when everybody else did proved critical as he slumped to sixth place.

Team Penske's Joey Logano finished in third to separate the Hendrick Motorsports pairing of Dale Earnhardt Jr and Jimmie Johnson, who fought back from an unfortunate pitstop midway through the race.

Both men pitted under green just before the fourth caution, but while Earnhardt would get the free pass, confusion surrounded Johnson after he failed to beat Truex to the line.

Both men argued they were the last driver on the lead lap before NASCAR officials decided to give Johnson the wave around prompting the six-time Cup champion to fight back through the field.

Rookie Chase Elliott staged a fantastic comeback to finish fifth after a transmission change before the race meant he started in 40th place.

Kevin Harvick looked strong during the race but a speeding penalty at the fourth caution meant he could not recover and finished 10th.

Matt Kenseth was also challenging for the win in the final stages but a loose tyre meant the 2003 Cup champion ended up 11th.

Austin Dillion caused the final caution in a huge 13-car pile-up when he had a moment coming out of Turn 2.

Johnson could not slow down enough and tagged the back of the Richard Childress driver as he struggled to collect the car.

Dillon slammed into the wall and speared back onto the track, collecting 13 others.
