Kyle Busch dominated the weekend at Pocono Raceway.

Busch secured the pole for the Axalta presents the Pocono 400 on Friday, and on Sunday afternoon, he led 100 of 160 laps.However, domination didn't lead to victory. A mistake by interim crew chief Ben Beshore cost Busch a chance at winning his first career race at the "Tricky Triangle."With Busch's full-time crew chief Adam Stevens missing because of a four-race suspension handed down by NASCAR last week for Busch's tire falling off at Dover, Beshore was faced with a race-changing decision with just 15 laps to go.A late race incident brought out the yellow, and the decision for Busch to either stay out or take tires was not an easy one for Beshore, but in the end his decision turned out to be the wrong one. Beshore decided not to pit, while the rest of the contenders did. Busch's older tires were too much to overcome as Ryan Blaney passed Busch with nine laps remaining to earn his first career Monster Energy NASCAR Cup Series victory. Busch finished ninth.Blaney's win means that Richard Childress Racing, Wood Brothers Racing, and Roush-Fenway Racing - which have all struggled to get in the winner's circle in recent seasons - all have a victory in the bank this season before Joe Gibbs Racing, which has been the most dominate team the past few years.HendrickdisappointmentsKyle Busch wasn't the only driver to walk away disappointed on Sunday. Fan favorite and successful Pocono driver Dale Earnhardt Jr., who was moving through the field nicely after having to start in the back because of an engine change, blew his second motor of the weekend.Blowing a motor isn't rare at such a horsepower heavy track like Pocono, but for a motor to blow twice in one weekend by driver error, now that's a different story.Earnhardt Jr. had some problems shifting throughout the weekend. When coming off of turn three shifting from third to fourth gear, he twice shifted into second instead, which then blew the motor. It's something that he must certainly fix before his next stop at Pocono in July."I just blew the motor up again, for the second time this weekend," said Earnhardt Jr. "Going down the front straightaway coming out of turn three you're in third gear and before you get to the flag stand you shift into fourth. We haven't changed the transmission, we haven't changed the shifter, nothing is different from last week or last year."I'm trying to go from third to fourth and I just keep going to second. I don't know why, I can't explain it, I wish I had an answer as to why that keeps happening. I'm concerned because we obviously have to come back here and we have road courses coming up where we shift a lot more than Pocono."Earnhardt Jr. came from the back all the way up to 15th position at the end of stage one before the motor mishap.Overall, Earnhardt Jr. and his Hendrick teammates, which didn't show much speed in qualifying, struggled on the day. Besides Chase Elliott, who came home with an eighth-place finish, the rest of the Hendrick drivers did not fair too well. Jimmie Johnson, Kasey Kahne, and Earnhardt Jr. all have posted victories at Pocono, but on Sunday break issues for Johnson and Kahne paired with engine problems for Earnhardt Jr. spelled the lackluster efforts.Kahne finished 35th, Johnson 36th, and Earnhardt Jr. 38th. The Hendrick drivers will have one more shot to redeem their poor performance on Sunday, July 30 at the Pennsylvania 400.
