Denny Hamlin kept his car at the top of the speed charts in Saturday’s final NASCAR Sprint Cup Series practice, a session cut short by a significant fluid leak at Dover International Speedway.

Hamlin pushed his Joe Gibbs Racing No. 11 Toyota to a best lap of 156.087 mph on the 1-mile concrete track. Hamlin also led Saturday’s early practice and secured the first starting spot with the Coors Light Pole Award in Friday’s qualifying.

As in Saturday’s early session, Hamlin’s JGR teammate Carl Edwards was second-fastest in the No. 19 Toyota with a lap of 155.602 mph. Paul Menard was third-best at 155.206 mph in the Richard Childress Racing No. 27 Chevrolet.

Matt Kenseth was fourth-fastest and Kyle Busch fifth as Joe Gibbs Racing entries claimed four of the top five spots on the practice leaderboard. Jimmie Johnson, a nine-time Dover winner, logged the sixth-best lap ahead of Sunday’s FedEx 400 benefiting Autism Speaks (1 p.m. ET, FOX Sports 1, MRN, SiriusXM).

The final session was originally scheduled for 50 minutes, but a major fluid leak from the rear of Dale Earnhardt Jr.’s Hendrick Motorsports No. 88 Chevrolet oiled a large portion of the track. Practice was stopped for approximately 13 minutes for extensive clean-up. Race officials added five minutes to the end of the session to make up for the red flag.

Defending Sprint Cup champion Kevin Harvick, the standings leader, was seventh-fastest in the final tune-up in the Stewart-Haas Racing No. 4 Chevrolet.

Hamlin stays the course in practice 2

Denny Hamlin continued his steady show of speed at Dover International Speedway, leading Saturday morning’s next-to-last NASCAR Sprint Cup Series practice.

Hamlin wheeled the Joe Gibbs Racing No. 11 Toyota to a best lap of 156.331 mph on the 1-mile concrete layout. A day earlier, he landed the Coors Light Pole Award, clinching the No. 1 starting spot for Sunday’s FedEx 400 benefiting Autism Speaks (1 p.m. ET, FOX Sports 1, MRN, SiriusXM).

Though Hamlin has three pole positions for the last six Dover events, he has yet to score a Sprint Cup victory at the Monster Mile. Hamlin already has wins in hand this season at Martinsville Speedway and in the non-points NASCAR Sprint All-Star Race.

Carl Edwards, a teammate of Hamlin’s at JGR and last weekend’s Coca-Cola 600 winner, clinched the second spot on the practice leaderboard with a 156.325-mph lap. His best time in the No. 19 Toyota was just one-thousandth of a second slower than Hamlin’s chart-topping lap.

Kurt Busch was third-fastest at 155.736 mph in the Stewart-Haas Racing No. 41 Chevrolet. Jimmie Johnson, a nine-time Dover winner in the Hendrick Motorsports No. 48 Chevy, was fourth-fastest at 155.723 mph. David Ragan, prepping for his third start in the Michael Waltrip Racing No. 55 Toyota, completed the top five at 155.602 mph.

Defending Sprint Cup champion and current points leader Kevin Harvick was eighth-fastest in the 50-minute session.

Final Sprint Cup practice is scheduled for 1-1:50 p.m. ET (FOX Sports 1).

JGR driver ready to race at Dover after Charlotte setbacks

DOVER, Del. — Bouncing back from last week’s health scare, Denny Hamlin comes to Dover International Speedway healthy for Sunday’s FedEx 400 benefiting Autism Speaks (1 p.m. ET, FOX Sports 1, MRN, SiriusXM).

The No. 11 Joe Gibbs Racing driver suffered from an intense migraine and nausea last week at Charlotte Motor Speedway, which were suspected to have been brought on by dehydration. On Friday, Hamlin revealed what actually could have been the cause.

"We had an exhaust leak in our car," Hamlin said at Dover. "We found a hole in our header and exhaust system that was leaking into our car, and that didn’t help at all either. We also had run the XFINITY race the day before, and we’re not doing that this week.

"I felt like I kept up with my fluids pretty well last week, but obviously it wasn’t enough. Obviously, the conditions of the car didn’t make things very easy for me. The headache had nothing to do with the dehydration. The migraine that I suffered I felt like was from the exhaust inside the car."
 
Hamlin was taken to the infield care center when he finished last week’s Coca-Cola 600 and later popped into the media center during Carl Edwards‘ victory press conference.

"My off day was 36 holes of golf and a full tennis match," Hamlin said after the race last Sunday. "Probably overdid it a little bit. I think the dehydration led to a migraine and I just felt nauseous the last 100 laps or so."

Hamlin won the Coors Light Pole Award at the "Monster Mile" and was the second fastest (163.532 mph) during the Sprint Cup Series opening practice session on Friday. This is the third Dover pole award for the Toyota driver, who is winless in 18 Cup starts at the 1-mile track.

Truex Jr.: ‘I don’t think it’s too early to start thinking about it’

DOVER, Del. — When a single-car team has a driver that has already earned three top-five and 11 top-10 finishes in 12 races and is currently sitting second in the driver standings behind last season’s Sprint Cup Series champion, discussions about expanding to a two-car garage begin to stir.

"I don’t think it’s too early to start thinking about it," Martin Truex Jr. told the media on Friday at Dover International Speedway. "I think that Barney (Visser, team owner) and Joe (Garone, general manager) have been thinking about it for a while. It’s just a matter of when is the time right.

"If the situation and everything works out the way they want it to, the way they want it to look I think it would be a good thing. I really like what we have right now. It’s working well and it’s hard to think about changing something. I think it would be a good thing for the team, and certainly they have the capabilities of making it work, I believe."

But with the Furniture Row Racing driver’s success this season, it seems as if the only missing piece of the puzzle is a win. Now with the New Jersey-native being back at his home track and the location of his first Sprint Cup Series win, perhaps a victory is in the cards. This weekend’s FedEx 400 benefiting Autism Speaks (May 31, 1 p.m. ET, FOX Sports 1, MRN, SiriusXM) will be the third-straight points race with the same No. 78 Chevrolet that he earned ninth- and fifth-place finishes with at Kansas and Charlotte, respectively.

"I feel like last year we were off quite a bit," Truex said of his 2014 Dover finishes (sixth and seventh place). "We came here and we still ran in the top-10 both races, really had a good run here for us last year. I kind of was looking back at that and thinking about that thinking ‘OK imagine what we can do there now.’ We will just have to see."

Jeff Gordon: ‘We have some work to do’

DOVER, Del. — Nine-time Dover winner Jimmie Johnson blazed through Friday’s opening round of practice under an overcast Delaware sky topping the speed charts. But when it came to qualifying his No. 48 Lowe’s Chevrolet later in the sun-drenched afternoon, Johnson only advanced to the second round and will start 14th in Sunday’s FedEx 400 benefiting Autism Speaks (1 p.m. ET, FOX Sports 1, MRN, SiriusXM).

Still, that’s the best of his Hendrick Motorsports team, which for the second consecutive race has not had any of its four cars advance to the final round of qualifying.

"In a sense maybe we didn’t make the changes we needed to, the car had so much speed in the first practice session,” Johnson told FOX Sports 1 following the second round of qualifying on Dover International Speedway‘s "Monster Mile."

"But the track is totally different right now. … We’ll learn and get smarter from it. This car has a lot of speed and we’ve won from much farther back, so I’m really not worried at all."

With a series-best three victories already this year (including one from a 37th-place starting position), Johnson may not be overly concerned. But his winless teammate Jeff Gordon conceded earlier in the day that his team is not performing at full potential.

Gordon will start 22nd on Sunday, and his teammates Dale Earnhardt Jr. and Kasey Kahne will roll off 16th and 25th, respectively.

"I wouldn’t call it urgency, but there is definitely a lot of hard work being put out to get that turned around," said the four-time Cup champ Gordon, who is retiring from full-time competition at the end of the 2015 season.

"This rule package that we have this year has not suited any of us very well. I know Jimmie has the three wins, which we all scratch our heads and are amazed that he has been able to do that. We don’t feel like we have really performed, any of us, to that level, but they (No. 48 team) have done an excellent job."

Gordon is currently Chase-qualified based on his points standings, but would prefer a win and a sure ticket in — especially in his final full-time season.

His No. 24 3M Chevrolet has a pair of top-fives and three pole positions in 12 races this season, and Gordon is a five-time Dover winner — including last fall.

"I think we are very conscious of the fact that we need to improve our performance, especially on the 1.5-mile tracks,” Gordon said. "We have not lived up to our own expectations and we are working extremely hard to fix that.

"I think right now if we execute flawlessly, we have a shot at winning. Be we haven’t been doing that either.

"We have some work to do.”

Johnson on P1: ‘We don’t agree with what has happened’

DOVER, Del. — Six-time NASCAR Sprint Cup champion Jimmie Johnson calmly and strongly reiterated his team’s position to appeal the P1 penalty NASCAR handed down to the No. 48 Hendrick Motorsports team this week.

An hour before posting the fastest speed in Friday’s opening practice at Dover International Speedway, Johnson spoke to reporters for the first time since the penalty was announced Wednesday and since his team filed an appeal Thursday.

"Definitely we don’t agree with what has happened and getting the letters and that’s why the appeal has taken place," Johnson said from Dover International Speedway before opening practice.

"I look forward to the appeal process running its course, and respect it and certainly hope for a different outcome once everything has run its course."

Johnson’s No. 48 Lowe’s Chevrolet team was penalized this week after receiving multiple written warnings from NASCAR for violations found during the May 16 Sprint All-Star Race and May 24 Coca-Cola 600 weekends at Charlotte Motor Speedway.

Multiple warnings warranted a P1-level infraction that would have given Johnson one of the last pit stall selections this weekend at Dover. By appealing the penalty, Johnson will still have the ability to pick a pit stall based on his qualifying position, which is important on the small and tight pit road at the 1-mile Dover concrete oval.

"I guess there is that part of it," Johnson said. "My qualifying record as of late hasn’t been so stellar, so we won’t know implication of that (appealing the penalty) until after qualifying.

"Then," he said, pausing, " the stories can run rampant then."

Johnson was fastest in practice with a speed of 163.867 mph followed by Denny Hamlin, Hendrick teammate Dale Earnhardt Jr. and David Ragan.

A victory Sunday in the FedEx 400 Benefitting Autism Speaks (1 p.m. ET, FOX Sports 1, MRN, SiriusXM) would be Johnson’s 10th at Dover and make him one of only five drivers (Richard Petty, Darrell Waltrip, David Pearson, and Dale Earnhardt) in NASCAR history to score double-digit wins on a track.

BKR driver wins second race of 2015

RELATED: Full race results | Updated series standings

DOVER, Del. — Tyler Reddick had a score to settle with Dover International Speedway, and on Friday he did just that, winning the Lucas Oil 200 NASCAR Camping World Truck Series race in his second start at the Monster Mile.

Reddick passed Erik Jones on Lap 193 of 200 and finished 1.255 seconds ahead of Daniel Suarez, who drove past third-place finisher Jones in the closing laps to take the runner-up spot.

The victory was Reddick’s second of the season in the No. 19 Brad Keselowski Racing Ford, and in the driver’s view, it atoned for last year’s eighth-place finish in which Reddick underestimated the physical toll high-speed racing at Dover can exact.

Specifically, his leg fell asleep as the race progressed.

"After what happened to myself last year, not knowing a lot about the g-forces in the corners here — I was kind of green when it came to asphalt racing," Reddick said. "We had a top-five truck last year, and to have something like that impede our progress in what would have been our first top five… to have something like that mess up what could have been potentially a breakout day for us are the things you can’t have happen in racing.

"I really wanted to come back here and run really strong, just like I want to run strong every given race. But (last year) gave me a little bit of extra fuel for the fire, and I knew I had to run good here — and we did."

Daniel Hemric posted a career-best fourth-place NCWTS finish in his first race at Dover. Series leader Matt Crafton ran fifth but saw his margin narrowed to 11 points by Reddick, who is second after six races.

Ben Kennedy came home sixth, followed by Keystone Light Polesitter Ryan Blaney, Brandon Jones, Johnny Sauter and Tyler Young. Suarez, Jones, Kennedy and Blaney, who finished among the top seven, are all NASCAR Next alums. 

Though Jones lost one position to Reddick in the series standings, he moved closer to Crafton, now trailing the two-time defending champion by 14 points. Sauter is fourth, 40 points behind Crafton, and could be considered the only other driver within realistic striking distance of the leader at this point in the season.

Like Jones, Suarez used a two-tire call to gain track position in the late stages of the race but felt race traffic hindered him in the closing laps.

"To be honest, I feel like we had a faster truck," said Suarez, a member of the 2014 NASCAR Drive for Diversity class, who posted his best finish to date in the series. "Traffic was everything. I was talking with my crew chief Jerry Baxter through the radio during the middle of the race. I told him, ‘I don’t care about tires, I need the track position.’

"For sure the track position was very important. Erik Jones he changed just two tires in the last pit stop and he was able to almost get the win and he was driving away, but traffic was a big problem for him and for me and I feel like for everyone. Traffic was something that was a gamble, but overall I feel like we learned some good stuff for tomorrow (in the NASCAR XFINITY Series race)."
