Jimmie Johnson the leader at the halfway point in Dover

Jimmie Johnson is the leader at the halfway point of the Citizen Soldier 400 at Dover International Speedway.
Johnson started eighth and has led 11 of 200 laps. He took the lead on a restart on Lap 190, passing Martin Truex Jr. Truex started second and has led 81 laps. He took the lead for the first time on Lap 6, passing pole-sitter Brad Keselowski.
Kyle Busch is the only other driver to lead during the first half of the event. Busch has led twice for 102 laps.
Chase drivers were eight of the top 10 at halfway with Johnson leading Truex, Keselowski, Matt Kenseth, Busch, Chase Elliott, Joey Logano, Denny Hamlin, Kasey Kahne, and Jeff Gordon.
There have been four cautions in the first 200 laps. Chase driver Kevin Harvick, who already is locked into the Round of 12 after winning last weekend at New Hampshire Motor Speedway, brought out the first caution on Lap 33 when he suffered a broken track bar mount. Following repairs in the garage, Harvick returned to the race on Lap 77 and was running 39th, 44 laps down at halfway.
Under the same caution, Chase driver Kyle Larson lost power in his No. 42 Chevrolet and had to be pushed to pit road. Larson lost a lap while the team worked on the car and then was called for a pass-through penalty for having too many crew members over the wall.
The second caution was for Ryan Blaney, who blew a tire coming off Turn 2 on Lap 104. Larson then brought out the third caution when he blew a tire on Lap 182. The fourth caution was for Larson’s teammate, Jamie McMurray, who blew an engine on Lap 193.

Jamie McMurray loses engine a few laps shy of halfway at Dover

Chip Ganassi Racing’s Chase for the Sprint Cup hopes suffered another blow as Jamie McMurray lost an engine just shy of the halfway point in the Citizen Soldier 400.
McMurray’s No. 1 Chevrolet had been off the pace for many laps before it gave up the ghost on Lap 193.
McMurray, who qualified for his second consecutive Chase, had entered Dover International Speedway 13th on the Chase grid. The top 12 drivers will advance to the second round.
This was the first year owner Chip Ganassi had put both of his cars in the Chase, and it seemed neither will advance from the opening round.
McMurray’s championship aspirations ended while teammate Kyle Larson was running in 32nd, four laps down after a series of miscues and problems.
During a caution for Larson hitting the wall on Lap 183, McMurray told his crew “I have to be down at least two cylinders, maybe three.”
Less than four laps after the restart, McMurray’s car began belching smoke.
“I was really happy with the car; we’ve had good cars for the last two months,” McMurray told NBC Sports. “I’m proud of my team, proud of our guys for all the hard work we put in. It stinks that it’s over this way.”

Martin Truex Jr. dominates at Dover for his fourth win of the season

Martin Truex Jr. further established himself as championship favorite by dominating the Citizen Soldier 400 at Dover International Speedway.
Already locked into the Round of 12 following a victory in the Chase opener at Chicagoland Speedway, Truex picked up his second win of in the first round after leading 187 of 400 laps Sunday afternoon. The victory is the second at Dover for Truex, a New Jersey native, who earned his first career win at his home track in June of 2007.
It is also his seventh career win and fourth of the season. Truex finished first, seventh, and first in the Chase’s first three races while leading a total of 360 laps.
“We’re not messing around, I guess,” Truex told NBC Sports of his first round performance. “I don’t know. What else can you say? We are here to get it done and golly, the best bunch of guys you could ever ask for and just amazing to drive their racecars and do what we’re able to do. I’m just ecstatic.”

Truex took control of the race after Jimmie Johnson, who led 90 laps, was penalized for having too many crew members over the wall during a round of green flag pit stops on Lap 280. Johnson had been leading at the time but would finish seventh, the first car one lap down.
The No. 78 of Truex then took the lead for the final time on Lap 374 after the race’s final round of pit stops. His margin of victory was seven seconds over Toyota teammate, Kyle Busch.
The top five were Truex, Busch, Chase Elliott, Brad Keselowski, and Matt Kenseth. The first four drivers eliminated from the Chase were Tony Stewart, Kyle Larson, Jamie McMurray, and Chris Buescher.
HOW TRUEX WON: Truex cycled to the race lead by seven seconds with 26 laps to go following the final round of pit stops.
WHO ELSE HAD A GOOD RACE: Chase Elliott earned his second top-five finish in the Chase with a third-place run … Team Penske put both cars in the top-10 with pole-sitter Brad Keselowski finishing fourth and Joey Logano finishing sixth … Jimmie Johnson recovered from a pit road penalty to finish seventh … Jeff Gordon earned his first top-10 finish in the No. 88 car with a 10th-place effort.
WHO HAD A BAD RACE: Kyle Larson finished 25th, six laps down after losing power in his Chevrolet, being issued a pit road penalty, and hitting the wall … Kevin Harvick broke a track bar mount and finished 37th … Ryan Blaney blew a tire and finished 38th … Jamie McMurray blew an engine and finished last, 40th.
NOTABLE: With his fourth win at Dover, Truex is now tied with Brad Keselowski and Kyle Busch for the most in the series. Dover is also the first track where Truex has scored multiple race wins. Truex has also now led more laps in the last six races (588) than each of his prior seasons entering 2016.
QUOTE OF THE DAY: “It feels good. Now it’s time to knock some more of these guys out because we’ve got this opportunity and I’m going to say we’re going to be the underdog in this next round, so let’s go do it.” — Austin Dillon on advancing to the Round of 12 in the Chase.
WHAT’S NEXT: The Round of 12 begins at Charlotte Motor Speedway with the Bank of America 500 on Oct. 8 at 7 p.m. ET on NBC.

REDDICK CAPTURES FIRST WIN OF SEASON,SHAKES UP CHASE

LAS VEGAS – Tyler Reddick outdueled Brad Keselowski Racing teammate Daniel Hemric to win Saturday night's NASCAR Camping World Truck Series DC Solar 350 at Las Vegas Motor Speedway.

The victory was Reddick's first of the 2016 season and marked the first time the Brad Keselowski Racing team had fashioned a one-two finish in the series.

Reddick led five times for 70 of the 146 laps around the 1.5-mile track, taking the advantage for the final time from Cole Custer shortly after the race's third caution.

Custer, who finished third in the No. 00 Chevrolet, faded from contention after a furious battle with Hemric, one that likely assured Reddick of the victory as the pursuers used up the grip in their tires.

Reddick's margin of victory over his teammate was 1.404 seconds as he completed the race at an average speed of 143.163 mph.

"We were spot-on from the beginning," said Reddick, who started 16th in the 31-truck field but reached the top three by the 19th lap. The victory was his third in the series and first since June 2015 at Dover International Speedway.

Ben Kennedy and William Bryan completed the top-five finishers. Christopher Bell, Johnny Sauter, Matt Crafton, pole starter Timothy Peters and Grant Enfinger were sixth through 10th.

Peters and Kennedy led the early stages of the race. Peters held the point until the 14th lap when Kennedy took over followed by Custer. The caution clock triggered the yellow flag at lap 39, giving Reddick the lead after pit service.

Reddick, Hemric and Custer exchanged the lead through most of the remainder of the event, which saw a dozen total lead changes among five drivers. Hemric led the second-most laps, 38.

Saturday night's race was the second of three in the NASCAR Camping World Truck Series Chase's Round of 8. While Reddick was not among the eight post-season qualifiers, a Hemric victory could have allowed the runner-up finisher to advance to the next round. As it is, he's 15 points outside the six-driver cutoff line heading into the Oct. 22 Talladega Superspeedway elimination race, the same as John Hunter Nemechek, who finished 16th in Las Vegas.

"Unfortunately, I was a spoiler for my teammate," Reddick said.

Hemic said it could be easy to be frustrated – so near yet so far – but noted Reddick did what he was supposed to do for the team.

"We're both racing for the win," he said. "We're doing all we can to win these races. He did everything picture-perfect."

New Hampshire winner William Byron, who's guaranteed to advance to the next round, continues as the points leader. Bell, Crafton, Kennedy, Peters and Sauter all are above the cutoff line after two of the three Round of 8 races.
