In what was supposed to be the rain free day of the weekend, rain halted the racing 53 laps into the 100 laps race and by the NASCAR rule book, once the race is passed halfway it is deemed official if weather comes. Pole-sitter Erik Jones was closing in on Larson when the rain hit the race track.
NASCAR waited an hour and 35 minutes before calling the event due to rain. Once the track was near dry it began to pour, which led the series director to call the remainder of the race.
Larson led on several different occasions for a total of 27 circuits. It marks the Chip Ganassi Racing drivers' fourth career win in 82 XFINITY Series starts, and his second career win at Pocono, winning an ARCA event two years ago.
"I'm happy with it," Larson said of the rain coming in and ending the race. "We were good, a little bit better than i thought we would be. We were more comparable to the Gibbs cars than I thought we would be based off practice and qualifying."
Jones finished second on the afternoon after starting from pole, but never leading a lap. For the majority of the 53 laps the No. 20 car was in the runner-up position, first chasing his teammate Kyle Busch then chasing Larson. He felt like this race was another race that she let slip away.
"We had by far one of the best cars in the field today, so it's unfortunate," Jones said of his second-place effort. "Our Camry was good, but just not enough time t get back to the lead and have a shot at it. It's pretty frustrating because this whole year has been a season of just missing it by that much. We missed it in a couple races by penalties and circumstances and today was another one of those days where we had another good shot at the win, but with the way it played out it just didn't work out for us."
Ty Dillon finished third, posting his fourth top-five finish of 2016.
After leading the opening 16 laps, Busch couldn't get back through traffic to take the lead back after making a pit stop under the first caution flag. Finishing fourth on the afternoon, he felt that the team was a step behind.
Joey Logano rounded out the top five after getting off-sequence with the competition.
Elliott Sadler, Paul Menard, Brandon Jones, Daniel Suarez and Alex Bowman rounded out the top 10.
Brennan Poole finished 12th, ending a streak of four consecutive top 10 finishes, which is a career-high in his rookie season.
On Lap 20, Justin Allgaier made contact with the wall in the "Tunnel Turn" which resulted in a 39th-place finish. The No. 7 team dropped to seventh in the points after starting the race third in the standings.
The series is set to return to action next Saturday at Michigan, where Busch is the defending winner of the event, which was his first race back in the XFINITY Series after his leg injuries last February in Daytona. .
After getting just 20 minutes of practice on Friday, the NASCAR Sprint Cup Series was able to go the full distance in final practice on Saturday at Pocono Raceway.
The session was led by Kyle Busch at 176.901 mph. Completing 21 laps, the No. 18 team focused strictly on race runs. The No. 18 will begin the 400-mile event from the outside of the sixth row, a place that he is searching for his first career victory at the "Tricky Triangle."
"With the way our cars at JGR (Joe Gibbs Racing) have been overall, I’m very optimistic that we could score a victory there this weekend or, if not, when we come back later in the summer," Busch said.
Kurt Busch was second on the leader board in the practice session. He laid down a lap of 176.800 mph, which was less than a half-tenth off his brother's time. The former Pocono winner will start from ninth on Sunday.
Jimmie Johnson was third on the board with a lap at 176.710 mph, Martin Truex, Jr. was fourth at 176.291 and Kevin Harvick rounded out the top five at 176.125 mph.
Pole-sitter, Brad Keselowski was sixth on the board. The No. 2 car ran 27 laps on the racetrack and the team was happy with the car they have on track.
"I think were decent, it's hard to say," Keselowski said. "We need to look at some data, but I don't think were far off. Starting up front gives you a lot of confidence for sure."
Keselowski's Team Penske teammate Joey Logano was seventh, with Matt Kenseth eighth, rookie Ryan Blaney was ninth and AJ Allmendinger fulfilled the top 10.
The younger Busch brother had the best 10 consecutive laps, while Harvick ran 34 laps, the most of all drivers.
For the fifth time in 2016, Erik Jones will start from the pole in an XFINITY Series race. In the second round of qualifying he laid down a lap of 175.926 mph, which was much faster than the rest of the field. In the first round of qualifying the No. 20 Toyota was over a half-second faster than second-place.
Kyle Busch has been fast since the No. 18 team unloaded on Thursday. He was second overall at 175. 203 mph. His only win at Pocono in NASCAR came last summer when he won in the Camping World Truck Series.
The third Joe Gibbs Racing driver, Daniel Suarez was third quick at 174.784 mph. It his 12th top-10 start of 2016, in 12 events.
Kyle Larson was fourth at 173.568 and Joey Logano rounded out the top five at 172.781 mph.
Elliott Sadler was sixth, Paul Menard seventh, Ty Dillon eighth, Justin Allgaier ninth and Alex Bowman rounded out the top 10.
The top 12 cars in the second round of qualifying were separated by two seconds.
Notable drivers to miss the top 12 cutoff were a pair of rookies led by Brennan Poole who posted the 13th best lap, with Brandon Jones 14th, Cup Series driver Aric Almirola 16th and Brendan Gaughan 17th.
Darrell Wallace, Jr. was the second to last car to attempt a qualifying lap in the opening round. The No. 6 Ford got loose getting into the corner and went for a long spin, keeping it off the wall. In doing so, Bowman was on track for his warm up lap and had to pull his car into the pits to cool the engine down.
Bowman posted the eight fastest lap even with a hot engine, while Wallace will have to come from the rear as he never made a full lap.
The green flag is set to wave shortly after 1:00 p.m. ET.
After Joey Logano was quickest in the first two rounds of qualifying, his teammate Brad Keselowski took the final round en route to his first pole of 2016 and first pole at Pocono Raceway. His previous best qualifying results at the "Tricky Triangle" were a pair of third-place efforts in 2014.
It was a speed of 181.726 mph that claimed the top spot. Logano ran a speed of 181.400 mph, nearly a tenth of a second off the pole-winning time.
"It was a really solid effort for Team Penske," Keselowski said. "To get 1-2 is hard to do, but we had great speed today. I wasn't really sure what to expect with the rain and all of the other variables that were thrown at us with no practice."
The last seven times that Keselowski has started on pole, he has finished in the top 10 each time with two victories.
After Logano, it was August winner Matt Kenseth who placed third at 181.316 mph. Kevin Harvick had the fourth best time at 181.192 mph and Carl Edwards rounded out the top five at 180.759 mph.
"I didn't do a very good job today," Harvick said of his fourth-place effort. "The car was a lot faster than the driver today. The guys did a job preparing a good job, but I wasn't in a good rhythm and didn't do a good job in any of the rounds to get everything out of the car that I needed to."
Tony Stewart will start sixth in his best qualifying effort since Michigan last August when he began that 400-mile race fifth.
Jimmie Johnson will start seventh, Dale Earnhardt, Jr. eighth, Kurt Busch ninth and Denny Hamlin rounded out the top 10.
Chase Elliott is the highest starting rookie in 13th with Rookie of the Year contender Ryan Blaney alongside in 14th.
The defending race winner, Martin Truex, Jr. posted the 17th quickest time in qualifying. The No. 78 team feels that they missed the setup completely and thought the track was going to be something different. It took them two tries to get through the first round, which put more laps on their tires, hurting the speed in Round Two.
"We just totally missed it off the trailer, which is unusual for our team," Truex said. "We were way off our first run in practice and had so many different ideas about what it might have been. It felt so bad that it felt like the tires were wrong or we had a bad set."
Final practice is set to begin at 11:30 on Saturday weather depending. It will be the only time that the teams will be able to practice on race trim because no driver completed more than seven laps in the opening practice on Friday.
Fog remained a factor for what turned into be just a 20 minute practice when rain came and halted cars from working on qualifying setup. 28 cars participated in practice, so if qualifying is rained out in the afternoon the starting lineup will be set by owner standings.
Carl Edwards posted the fastest single lap speed at 179.802 mph, which was over one mph faster than Kevin Harvick, who recorded the second fastest lap. If rain cancels qualifying, the No. 4 Chevrolet would start from the pole on Sunday.
Last year's pole-sitter for this event, Kurt Busch was third on the leader board at 178.649 mph. Paul Menard was fourth at 178.250 mph and defending Cup Series champion Kyle Busch rounded out the top five.
Jimmie Johnson, Casey Mears, Joey Logano, Greg Bffle and Tony Stewart rounded out the top 10.
Three drivers were tied for most laps ran in the practice session at seven. Cup Series rookie Chris Buescher led the way in that category at 23rd. Michael Annett and Brian Scott also completed seven laps and were the two slowest cars on one lap speed.
Notable drivers who didn't complete a lap were August winner, Matt Kenseth, Ryan Newman and Austin Dillon.
Qualifying is set to role at 4:15 p.m. ET if rain moves out of the Pocono Mountains.
