NASCAR’s top two divisions, the Sprint Cup Series and Nationwide Series, are at Las Vegas Motor Speedway this weekend. Although the NASCAR Camping World Truck Series is off until the end of March when they return to action at Martinsville, fans can expect to see reigning truck series champion Matt Crafton on Saturday in the Nationwide race.

The new duo didn’t disappoint as Harvick dominated, leading 224 of the 312 laps, including the final 62 circuits, for his track record fifth series win. Harvick and his team head to Las Vegas in fourth place, with their Chase ticket all but punched. Earnhardt’s Confidence On Display Early In 2014 If there’s something different about Dale Earnhardt Jr. this season that might have been lacking in years past, it’s his confidence. He admits that his strong performance during last season’s Chase has provided him with more self-assurance through the first two races of 2014, and it shows with a victory in the Daytona 500 and a runner-up finish at Phoenix. Although he has never won at Las Vegas – the site of Sunday’s KOBALT 400 – he’s finished second there twice. So, fans should expect his confidence to continue. Busch Brothers Return Home With Work To Do Kurt and Kyle Busch’s seasons have not started the way they would have liked, but perhaps a little bit of hometown magic is just what the two Vegas natives need. When the Busch brothers arrive in Sin City for Sunday’s KOBALT 400, Kyle will be looking to improve upon his 14th-place position (-29), while Kurt looks to do the same in 30th (-61). In 10 starts at the 1.5-mile speedway, Kyle has one win and four top fives. Kurt is winless and has three top 10s in 13 starts. NASCAR NATIONWIDE SERIES – BOYD GAMING 300, SATURDAY, MARCH 8 Las Vegas Homecoming For Gaughan, Kwasniewski Who says you can’t go home? Brendan Gaughan and Dylan Kwasniewski are both doing just that this weekend when they get to compete in the Boyd Gaming 300 at Las Vegas Motor Speedway. Saturday’s race will mark Gaughan’s fourth NASCAR Nationwide Series start at the speedway while Kwasniewski will be making his debut. They are not the only hometown drivers competing in the race; Kyle Busch returns behind the wheel of the No. 54 looking his first series victory at Las Vegas. Sadler Strong In 2014 A new season is proving to a good thing for Elliott Sadler. After finishing second in the series standings in 2011 and 2012, the JGR driver was winless in 2013 and finished fourth in the points. In two races this season, Sadler has two top-six finishes. He captured the pole at Las Vegas Motor Speedway – the site of Saturday’s race – in 2012 and has two top fives. Nationwide Regulars Shine In Vegas Regan Smith was the first NASCAR Nationwide Series regular to take home a victory in 2014. The odds are good that another series regular could do the same this weekend at Las Vegas. The last two races held at the speedway have been won by series regulars – Ricky Stenhouse Jr. (2012) and Sam Hornish Jr. (2013). Two Races Down, Rookies Continue To Show Strength After the first two races of the season, Sunoco Rookie of the Year title contenders Ty Dillon, Dylan Kwasniewski and Chase Elliott continue to impress. The trio have each at least one top-10 finish and are currently fourth, fifth and seventh in the series standings, respectively. Dillon is the only one of the three to have a NASCAR Nationwide Series start at Las Vegas. In last year’s event, he finished 11th. source – NASCAR communications
