Qualifying

Martin Truex Jr. scored the pole with a time of 50.211 and a speed of . “The car felt really good for me today,” Truex said. “We’ve obviously got speed now we’ll use the rest of the weekend to fine tune some things and get ready for Sunday. Love this track and looking forward to having some fun on Sunday and trying to get to Victory Lane.”

Carl Edwards, who qualified second, said as he "crossed the line, I felt like, 'That’s it.' But after seeing what (Truex) ran, I thought 'Well, maybe I could go back and change this or that,' but that was a really good lap for me. It just was. You can always go back and pick your lap apart, but the last two weeks, Indy and here, I was pretty proud of my lap, and they just got us."

Paul Menard, who qualified third, said ''we are not where we expected to be and need to be in points, so we had to make a change. Danny (Stockman) came in here and gave us a good car right off the truck. We stuck in qualifying trim all day. We know we have to improve our qualifying that just starts your race off way better. A good way to start it off.”

Qualifying was delayed 20 minutes due to a "glitch" with the laser inspection station. “We had a little bit of a glitch this morning at the opening of inspection with our laser platform,” Scott Miller, NASCAR's senior vice president of competition and racing development, told NBCSN. “We got it rectified quickly.”

Race

First half The race was postponed from July 31 to August 1 due to rain. Under overcast Pennsylvania skies, Martin Truex Jr. led the field to the green flag at 12:10 p.m. The field mostly rode around until the first caution of the race flew on lap 16. It was a scheduled competition caution for overnight rain. Brad Keselowski opted not to pit and assumed the lead. Jimmie Johnson was tagged for his crew being over the wall too soon and restarted the race from the tail end of the field.

The race restarted on lap 20. Greg Biffle got the jump on Keselowski and assumed the lead as the second caution of the race flew for Martin Truex Jr. suffering a right-front tire blowout and slamming the wall in turn 2. “A lug nut bounced off the ground, fell in behind the wheel behind a pit stop,” Truex said. “It’s just bad luck honestly. I knew something wasn’t right in (turn) one and two and I got real tight off of two on that restart and went down the back and was like, ‘Ah, it feels okay.’ And, as I got closer to the tunnel turn I felt it start to go down and by the time I let off and tried to slow down it was just going straight for the fence.” He was spared a last-place finish by Reed Sorenson, who exited the race on lap 29 with engine issues.

The race restarted on lap 23. Biffle maintained a quarter to half a second gap over the second-place car for a large portion of the run until Joey Logano drove under him in turn 2 to take the lead on lap 33. Bad luck continued for Truex as he cut down his left-front tire and was forced to make an unscheduled stop on lap 41. A number of cars began hitting pit road on lap 49. Jeff Gordon was tagged for speeding and was forced to serve a pass through penalty. He was eventually black-flagged. Kevin Harvick passed Logano going into turn 1 to take the lead on lap 52. He surrendered the lead to pit the next lap and handed it back to Logano. He pitted the next lap and handed the lead to Austin Dillon. He pitted the next lap and the lead cycled to Keselowski. Danica Patrick, Michael McDowell and Ricky Stenhouse Jr. were tagged for speeding on pit road and were forced to serve pass through penalties. Patrick was shown the black flag with the white cross, which meant she was no longer being scored until she served her pass through.

Harvick passed by Keselowski to retake the lead on lap 62. The third caution of the race flew on lap 66 for a two-car wreck on the frontstretch. Exiting turn 3, Aric Almirola made contact with Jeb Burton, came across his nose and made contact with the wall. Kyle Larson opted not to pit when the leaders pitted and assumed the lead.

The race restarted on lap 73. Larson and Dillon battled back and forth for eight laps until Dillon made contact with Larson in turn 3 on lap 82. This allowed Logano to slip by and retake the lead on lap 83. Larson said after the race that he doesn't think "you ever want to expect contact, but obviously we were racing really hard. I was doing all I could to stay in front of him, and he was doing all he could to get by me. We battled hard down the frontstretch one time, and then he got back to my inside into Turn 3. I left him plenty of room. I was just going to try and run side-by-side with him again and try and slow him down on the frontstretch. I guess he got loose underneath me and got into our door. That was pretty frustrating at the time, but it happens to not even really matter. That part of the race doesn't matter at all. It doesn't mean one thing to me." The fourth caution of the race flew on lap 85 for rain in turn 1.

Second half

The race restarted on lap 92. Matt Kenseth, who stayed out under the third caution, hit pit road from second on lap 96. The fifth caution of the race flew on lap 100 for Truex suffering a tire blowout in turn 1. Larson opted not to pit and assumed the lead.

The race restarted with 57 laps to go. The sixth caution of the race flew for a two-car wreck in turn 2. Rounding the turn, Logano was racing Ryan Newman to his outside and Denny Hamlin to his inside when Chase Elliott got to his inside, got loose, got into Logano and sent both of them into the wall. Elliott continued spinning down the track into the inside wall. Elliott said he "came off (Turn 1) and those guys were three-wide, I thought Denny had the best run so I elected to push him and I thought that would be a good move to kind of get him past them and hopefully he would drag me by. I just got next to (Logano) and got in there. I thought I slowed down enough to not get loose, but I got loose and collected him. I apologize to the No. 22 guys – it was completely my fault. I apologized to my guys as well. They gave me a really good car today.”
