  • XFINITY Qualifying procedure for 2015: In the NASCAR XFINITY Series, cars starting in positions 1-33 will be determined by their fastest single lap during qualifying in descending order with the fastest qualifier starting first. The next six positions will first be assigned to the highest ranking cars in owner points that have attempted all of the races, have not already earned a starting position through qualifying and have entered the event by the posted entry deadline. The final starting position will be awarded to the most recent eligible past champion driver. If there is no eligible past champion driver, then a seventh car will make the field based upon owner points.
    Prior to this enhancement, the top 30 cars in owner points were guaranteed a starting spot in each event. Now, a maximum of seven cars will be locked into a given NASCAR XFINITY Series race. If a qualifying session is cancelled because of inclement weather, the field will be set per the rule book with starting lineups determined by practice speeds.

    Hometown Hero: Gaughan Heads Home

    Who says you can’t go home?  Brendan Gaughan does just that this weekend as he competes in the Boyd Gaming 300 at Las Vegas Motor Speedway. Gaughan has four series starts at the speedway including two top-10 finishes. The Las Vegas native will compete in the NASCAR XFINITY Series race on Saturday and the NASCAR Sprint Cup Series race on Sunday.

    Sunoco Rookie Spotlight: Cale Conley & Harrison Rhodes

    Rookie Standings Update: Darrell Wallace Jr. captured the Sunoco Rookie of the Race award at Atlanta for being the highest finishing rookie in the race. Wallace is currently second in the ROY standings one point behind Ross Chastain.

    This week’s Sunoco Rookie spotlight shines on Cale Conley and Harrison Rhodes.

    Cale Conley: Conley is currently fifth in the Sunoco Rookie standings seven points behind the rookie points leader Ross Chastain. Conley, a 22 year old who hails from Vienna, West Virginia is driving the No. 14 TriStar Motorsports Toyota for car owner Mark Smith.  Conley has 13 series starts, posting one top-10 finish, last season at Kentucky. In his two starts this season he has finished 30th (Daytona) and 35th (Atlanta). This will be Conley’s NASCAR national series debut at Las Vegas Motor Speedway this weekend.

    Harrison Rhodes: Rhodes is currently last in the Sunoco Rookie of the Year standings with nine points, due to failing to qualify for the race at Daytona. Rhodes made his first series start last weekend at Atlanta where he started 35th and finished 34th. At the age of 21, Rhodes has made 14 series starts dating back to 2013. This season he behind the wheel of the No. 0 Chevrolet for car owner Andrea Nemechek.

    Elliott, Smith and Scott Make Biggest Moves In The Standings

    Following a surprisingly disappointing start to 2015 for Chase Elliott, Regan Smith and Brian Scott, who all finished 25th or worse at Daytona, the trio was able to bounce back in impressive fashion this past weekend at Atlanta. All three drivers gained 11 or more positions in the series standings - the most in the series following Atlanta.

    The 2014 series champ, Chase Elliott, finished 28th at Daytona putting him 20th in the series standings. This past weekend Elliott was able to rebound considerably. He finished fifth at Atlanta jumping 12 positions in the standings from 20th to the top 10 (eighth). Watch for Elliott’s ascension up the standings to continue this week at Las Vegas. He finished in the top five in his one and only start there, last season. 

    Elliott’s JR Motorsports teammate Regan Smith was caught in an accident at Daytona ultimately finishing 35th in the season opener. Smith’s finish at Daytona had him 26th in the points standings, but last weekend at Atlanta he was able to capitalize on his situation. Smith finished in the top 10 and in doing so leap frogged 12 positions in the series points standings from 26th to 14th. Smith has made five starts at Las Vegas posting two top-10 finishes.

    Of the three biggest movers in the point standings this week, Brian Scott moved up to the highest point standings position (seventh).  Scott finished 25th at Daytona and was 18th in the points heading to Atlanta. Scott moved up 11 positions in the standings following his seventh-place finish at Atlanta and all signs point to Scott’s momentum not slowing at Las Vegas. In his last two starts at the 1.5-mile track he has posted two top-10 finishes.

    After Two We Have Three: The Owner Points Lead Is Split Three Ways

    After two races the NASCAR XFINITY Series has a three-way points tie for the owner standings lead among car owners Jack Roush (No. 60 Ford), Richard Childress (No. 3 Chevrolet) and Roger Penske (No. 22 Ford) with 83 points each.

    When it comes to NASCAR XFINITY Series owner titles, all three car owners have enjoyed success. Roush has two series owner titles. He won his first series owner title in 2002 with driver Greg Biffle. His second came in 2011 with multiple drivers. This season Chris Buescher drives the No. 60 Ford full-time for Roush Fenway Racing.

    Childress is tied with Joe Gibbs for the series’ most owner titles with four each. Childress won his first in 2001 and his third in 2006 with driver Kevin Harvick. He won his second and fourth owner titles in 2003 and 2007 with multiple drivers behind the wheel.  This season his grandson Ty Dillon is driving the No. 3 Chevrolet for Richard Childress Racing.

    Penske is returning from back-to-back NASCAR XFINITY Series owner titles (2013, 2014) with the formidable No. 22 Ford team. Penske has captured both titles by rotating both veteran and upcoming drivers in the seat of the No. 22. This weekend at Las Vegas Brad Keselowski will be in the No. 22 to defend his win from last season at the 1.5-mile speedway. 

    NASCAR XFINITY Series Etc.
