Sprint Cup Series lays first rubber on track after rainy morning; Nationwide Series has practices combined

RELATED: Play NASCAR Fantasy Live | Sign up for RaceView today

NATIONWIDE SERIES PRACTICE | RESULTS

Ryan Blaney topped the leaderboard in the lone Nationwide Series practice session, putting the No. 22 Team Penske Ford in the first position with a lap of 180.048 mph. Rookies Chris Buescher and Ty Dillon were close behind but couldn’t top the 180 mph mark, taking second and third with laps of 179.880 and 179.456, respectively. Buescher ran the most laps of the session with 55, but scored his best lap in the Roush Fenway Racing Ford on his 27th turn around the track.

Kyle Busch and Trevor Bayne completed the top five. Busch took the No. 54 Monster Energy Toyota for a spin earlier in the session, but kept it out of the wall, preventing any major damage. After some adjustments in the garage, Busch was able to move his ride up towards the top of the leaderboard. Dakoda Armstrong also faced issues handling his No. 43, spinning in Turns 2 and 3 to bring out a caution flag during practice, ending the session in 23rd.

Points leader Chase Elliott‘s best effort of 178.743 mph put his No. 9 Chevrolet in the 13th position on the leaderboard. His closest competition for the series title, teammate Regan Smith, was just behind in 16th place with a lap of 178.171 mph.

After the first scheduled practice was canceled due to rain Friday morning, the second session — originally slated to run from 3 to 4:20 p.m. ET — was extended to a 4 to 5:30 p.m. ET practice.

Qualifying is scheduled for 12:15 p.m. ET on Saturday, with coverage on FOX Sports 2. The Kansas Lottery 300 will follow at 3:30 p.m. ET, and will be televised on ESPN.

SPRINT CUP SERIES PRACTICE 1 | RESULTS

After a rainy morning at Kansas Speedway, the NASCAR Sprint Cup Series went out on schedule to lay rubber onto the clean track. Chase contender Jeff Gordon topped the leaderboard with a fastest lap of 196.257 mph, followed by Kevin Harvick, whose lap of 196.178 mph showed the No. 4 will once again be one of the fastest cars on the track. Gordon and Harvick are both defending winners at the track, with Gordon winning the May race at Kansas Speedway and Harvick winning the fall race last year.

Greg Biffle and Aric Almirola, who were both eliminated from the Chase after last weekend’s race at Dover International Speedway, practiced as though they were still in contention, both placing inside the top 10, with Biffle’s lap of 195.730 mph placing him third on the leaderboard. Almirola ended the session in ninth. Kyle Larson was fourth-fastest, with fellow rookie Austin Dillon in rounding out the top five.

Kasey Kahne, Dale Earnhardt Jr. and Ryan Newman were the only drivers among the remaining Chase competitors to place in the top 10, finishing seventh, eighth and 10th, respectively.

Team Penske drivers Joey Logano and Brad Keselowski, both winners in the Challenger Round of the new Chase for the NASCAR Sprint Cup format, were 12th-fastest and 18th-fastest, respectively. Among the other Chase contenders, Jimmie Johnson was 14th-fastest, Carl Edwards was 21st-fastest and Kyle Busch 25th-fastest, with the Joe Gibbs Racing driver at the bottom of the leaderboard among the post-season players.

Qualifying for the Hollywood Casino 400 is scheduled for 5:45 p.m. ET on ESPN2.

Sprint Cup Sunoco Rookie of the Year contender to pilot the No. 5

RELATED: Play NASCAR Fantasy Live | Sign up for RaceView today

Alex Bowman, a Sunoco Rookie of the Year contender for BK Racing in the NASCAR Sprint Cup Series, will drive the No. 5 NASCAR Nationwide Series car at Charlotte Motor Speedway in the Blue Cross Blue Shield Drive for the Cure 300 (Oct. 10, 7:30 p.m. ET, ESPN2).

FULL SERIES COVERAGE

The team announced it via a JRM 360 video on Thursday, showing Bowman sneaking his way into the shop and putting his name above the door. Watch the video below.

Co-owner Kelley Earnhardt Miller talked about Bowman getting behind the wheel on "The Morning Drive" on SiriusXM NASCAR Radio on Friday.

"We had an opening in our car for Charlotte and an opening in Phoenix this year so they’re excited about running Charlotte and if they can put some funding together for Phoenix," Earnhardt Miller said. "For us, our original business for JR Motorsports is to build that talent and send them to the next level. Alex had the opportunity to run in the Sprint Cup car this year.

"Being on the track every week is important so we’re excited about him and his talent and hopefully seeing if we can put something together in the future with somebody like him."

Earnhardt Miller also looked ahead to 2015, noting sponsorship on championship contender Regan Smith‘s car is almost complete after Dale Earnhardt Jr. announced on Twitter earlier this week that Smith would return.

"We’re going to have Kasey Kahne, I think, drive a few more races for us in the 5 car so that’s about the only difference," Earnhardt Miller said. "We have about six races open on Regan’s car for sponsorship so we’re situated pretty good…."

Storms in Kansas City area put events on hold

KANSAS CITY, Kan. — Steady rain Friday morning has put NASCAR’s on-track activity at Kansas Speedway on hold.

FULL CHASE COVERAGE

• #MyChaseNation

NASCAR Nationwide Series opening practice was scheduled to start at noon ET, but a cold, driving rain and wind caused the 50-minute session to be canceled. Opening practice for the NASCAR Sprint Cup Series was scheduled at 1 p.m. ET for the fourth race in the Chase for the NASCAR Sprint Cup playoffs.

The lone Nationwide practice will now take place from 4 to 5:30 p.m. ET, and Coors Light Pole Qualifying for the Sprint Cup field (5:45 p.m. ET, ESPN2) is so far on schedule at the 1.5-mile track.

Sunday’s Hollywood Casino 400 (2 p.m. ET, ESPN) marks the opening race in the Contender Round, the second three-race series of eliminations in the new Chase postseason format. Just 12 drivers remain title-eligible after last weekend’s cut at Dover International Speedway; the championship field will be trimmed to eight in two weeks at Talladega Superspeedway.

Kevin Harvick enters the 400.5-mile event as the defending race winner. Jeff Gordon, who prevailed last weekend at Dover, also won Kansas’ most recent race May 10.

Bowyer to medical personnel: ‘Get the hell out of my way’

RELATED: Follow your picks in the Perfect Chase Grid Challenge for chance at $100,000 prize

KANSAS CITY, Kan. — When Clint Bowyer‘s phone rings these days, he’s on alert. That’s why it’s now more frequently found with the volume up than on vibrate — just in case there’s a call coming in from what he calls "headquarters."

Bowyer checked his phone Friday during his news conference at Kansas Speedway, dismissing the incoming call when it turned out not to be from his wife, Lorra, halfway across the country with the couple’s 2-day-old son, Cash Aaron Bowyer. Friends and family had warned Bowyer that his life was about to undergo a dramatic change with the Wednesday birth of his first child — and with more than just his phone settings — but the 35-year-old driver wasn’t so sure.

"You’re like, ‘There’s no way,’ then all of the sudden that little gremlin comes out of there and you’re like, ‘Oh my God, this is real,’ " Bowyer said before making reference to his frenetic bedside manner during the process. "I was probably not the norm as far as a spectator in an event like that. In the room there I was high-fiving people and I was kind of pushing the doctor out of the way at one point because I was trying to get a better view of him coming into the world. Of course, the nurses are trying to hold me back and they’re like, ‘You can’t get that close.’ I’m like, ‘Get the hell out of my way, here he comes.’ It was a lot of fun. We were all laughing."

• #MyChaseNation

With one life-altering experience under his belt this week, Bowyer sets his course toward a what could be a career-defining victory at his home track in Sunday’s Hollywood Casino 400 (2 p.m. ET, ESPN). A Bowyer win would almost certainly align the planets toward turning the center of the sports universe to Kansas City, where the fountains are flowing bright blue in honor of their Royals’ return to the baseball playoffs and where Chiefs fans continue to bask in the home team’s Monday Night Football thrashing of the New England Patriots.

Bowyer had turned the TV off Tuesday night before the Royals’ victory advanced them to the American League Divisional Series against the Angels. Then came the mid-morning commotion of the impending childbirth.

"I’m like, ‘Honey, you ain’t going to believe this, but the Royals won,’ " recalled Bowyer, demonstrating an uncanny sense of domestic timing. "Now we’re arguing about the Royals winning and they’re carting her out the door and I’m like, this is crazy."

The choice of Baby Bowyer’s name offers a nod to American music legends Johnny Cash and Elvis Presley, whose middle name was Aaron. Though Bowyer wouldn’t confirm whether any musical influence was involved in the decision, he did say that some alternates didn’t make the final cut.

"Well, she wouldn’t go for Cle-Bo — Cletus Bocephus," Bowyer said. "That’s the one that me and my friends came up with one night at the campfire, and she was definitely down on that. So we went with Cash."

While his life at home has changed forever, so have his old stomping grounds. Bowyer — who claims Emporia, Kansas, some 100 miles from Kansas Speedway, as his hometown — was still three years away from competing in NASCAR’s national series when the 1.5-mile track began hosting the Sprint Cup tour in 2001. Since those beginnings, the area around the speedway has built up into a thriving community.

"This place was the bad part of town," Bowyer said. "To see what has become of this area and to watch the first race here, I remember being down in the infield on top of a motor home, I don’t remember who it was, but I was down watching the very first race here. Watched the shopping center being built, watching the baseball diamonds and now the soccer fields, the casino — all of this area has really become one of the best places to be in Kansas City and it all hubs around this race track. That’s the impact this speedway did for this community."

Motorsports journalist Holly Cain the first name to grace the No. 15 Toyota

RELATED: Photos of how NASCAR is raising awareness

KANSAS CITY, Kan. — Clint Bowyer‘s rambling news conference Friday at Kansas Speedway touched all the bases — from his days-old transition into fatherhood to his love of Kansas City sports teams and growing up in the area around the 1.5-mile track. But it also included a special guest and a heartfelt show of appreciation.

Bowyer will tackle the fourth race of the Chase for the NASCAR Sprint Cup postseason at his hometown track with a special pink paint scheme on his Michael Waltrip Racing No. 15 Toyota, helping to raise awareness in the fight against breast cancer through a partnership with the Living Beyond Breast Cancer association. But in addition to the new look for the 5-Hour Energy livery, he’ll be carrying a special name over the passenger door: That of NASCAR.com’s Holly Cain.

FULL CHASE COVERAGE

"She’s a writer that’s been in this sport since I’ve been in it, always a great personality among all the media members, who is going through breast cancer right now," Bowyer said. "To have her on the right side going with me around the race track this weekend means a lot to me."

Cain, a veteran in the field of motorsports journalism, was diagnosed with breast cancer this summer. She continues to regularly contribute to NASCAR.com as a well-respected reporter, even as she undergoes a rigorous regimen of chemotherapy and other treatment for the illness.

Friday, she joined Bowyer’s news conference by phone to offer a touching thank-you for the team’s contributions to the cause.

"I have an 11-year-old daughter and a 13-year-old son, and I was able to show them the car this morning," said Cain, whose name is flanked by a pink ribbon on the right and the flag from her home state of Florida on the left. "After what’s been some difficult times for them watching me go through this as a breast cancer patient, it brought a huge smile to their face. They think it’s pretty cool and I appreciate that on their behalf.

"Now knowing about this on a very personal level, I really appreciate the work that organizations like Living Beyond Breast Cancer do, and I see what it can do firsthand."

Bowyer said his car will feature the same paint scheme in the next two races, at Charlotte and Talladega. In each race, a new name of a person affected by breast cancer will adorn the right side of the car.

JR Motorsports driver still aims for Cup ride, but content with fast cars in the meantime

RELATED: Play NASCAR Fantasy Live | Sign up for RaceView today

KANSAS CITY, Kan. — Regan Smith has made no bones about his long-term goal of returning to NASCAR’s premier series at some point in his racing career. For the time being, there’s something to be said for feeling at home.

Team owner Dale Earnhardt Jr. first tweeted the news Wednesday that Smith had signed the papers that would keep him at JR Motorsports in the NASCAR XFINITY Series (now the Nationwide Series) next season. Friday, Smith arrived at Kansas Speedway ahead of Saturday’s Kansas Lottery 300 (3:30 p.m. ET, ESPN) with any uncertainty around his 2015 plans removed.

"Just excited to be back and fortunate to have a great place to call home and a great place to race at with good people, good sponsors and fast race cars," Smith said. "As a driver, that’s something that you always look for, and it’s important. You want to have an opportunity to go out there and showcase what you can do every week. … I’ve learned a lot over the past two years, and I’m sure I’m going to learn a lot more next year, even."

FULL SERIES COVERAGE

The one-year extension means that Smith will return to the JRM fold for a third straight season. He wound up third in the series standings last year and ranks second this season, 26 points behind rookie teammate Chase Elliott with five races remaining.

Smith contributed a victory in the season-opening event at Daytona International Speedway in what’s been a banner year for JR Motorsports. The team has posted nine wins among four drivers, with Kevin Harvick (4), Elliott (3) and Kasey Kahne (1) adding the others. But the biggest change hasn’t necessarily been the increase in Victory Lane visits.

"I think we’ve had a lot more consistency in drivers every week in the cars, with myself running the whole year, with Chase running the whole year, Harvick’s run the majority of races on the No. 5 car — it just seems like we’ve had that consistent feel to it," Smith said. "As a whole, I feel like we’ve taken another step forward from last year even as a company."

The growth manifested itself with the team’s first-ever four-car effort back in April at Texas Motor Speedway, where Elliott passed Harvick for his first career Nationwide victory. Since then, Smith and Elliott haven’t fallen out of the top three in the season-long standings.

The success has been fun to watch for Earnhardt, who not only welcomed the continuity for 2015 but suggested that he might take more of an active role behind the wheel for JRM later in his career.

"I am really happy that we are basically going to have a carbon copy of what we did this year next season," Earnhardt said. "We have had a lot of success and I think we can build on that and everything is going to stay in place and we are going to go on down the road. On down the road is just 12 months. When you talk about the Cup Series you look a little further. I would like to race for that company one day, so I hope to keep it healthy until that opportunity presents itself — whenever I’m done Cup racing to jump in a Nationwide car and do that for a couple of years in my own shop."

For Smith, the short-term goal is chopping into his rookie teammate’s points lead and putting his No. 7 Chevrolet in position for a title. The ultimate goal is a return to the NASCAR Sprint Cup Series, which he called home for almost every race from 2008-12 and where he scored his biggest win — a triumph in the Southern 500 at Darlington Raceway in 2011.

While some loose ends still remain untied among the "silly season" moves and Sprint Cup vacancies for next year, Smith felt the time was right to sign the dotted line.

"I definitely want to get back to Cup. I don’t know that I’ve ever denied that or said that I don’t," Smith said. "That’s the goal and I’ve proved that I belong there and get to race on Sundays and run the longer races again. Naturally, there are some openings on paper that appear on that side. I think a lot of things still have play out on the Cup side — a lot of things look like they’re still taking place over there and there’s some quality race teams still trying to figure out what they’re doing. At the time, I felt like it was time to go ahead and start trying to solidify some things for next year and know generally speaking where I’m going to be."
