5:37 pm - With his in in the Sam's Town 300, Hornish extended his series points lead to 19 over Justin Allgaier, Elliott Sadler and Brian Scott who have 108 points apiece.

That will do it for today's coverage from LVMS. We'll be back early tomorrow to bring all the action from the Sprint Cup Series Kobalt Tools 400.

5:00 pm - Sam Hornish led 114 of 200 laps to become the first driver to drive the new Ford Mustang to victory in the Nationwide Series. It was the first NASCAR victory for Penske Racing at LVMS and the first in the series for crew chief Greg Erwin. Hornish was able to hold off Kyle Busch to win by 1.1 seconds. “We were so close at Daytona,” said Hornish. “I didn’t know until this morning that this was the Sam’s Town 300. It already had my name on the trophy. The car was awesome today. When you have a car that is good you are always worried something bad is going to happen or you will get caught in somebody else’s problem. I am glad that didn’t happen today.”

“We had a really good car,” said Busch, who was seeking his second consecutive victory. “The hard work pays off and makes my job look a little bit easier. The second to the last and last run I felt like our car was really good. Sam was just that much better than us. When he stepped on the gas, it went forward in a hurry.”

3:59 pm - Hornish records his 2nd Nationwide Series victory. Kyle Busch finishes 2nd, followed by Brian Vickers, Trevor Bayne and Elliott Sadler.

12:30 pm – Martin Truex ran the fastest lap of the final practice session at 188.383 mph. Carl Edwards, Kyle Busch, Jimmie Johnson and Mark Martin were 2nd through 5th.

The track will quickly get the track set up for pre-race festivities with the green flag scheduled to drop at 1:15 pm.

Boyd Gaming and Speedway Motorsports have extended their agreement for title sponsorship of the Sam’s Town 300 through 2017. The agreement continues one of the long running agreements of its kind in the sport and ensures the partnership will reach the 20-year mark.

11:37 am – We were just a couple minutes into the final practice session when Denny Hamlin spun off Turn 4. The car has no visible damage and he’s able to drive it back to the garage.

11:18 am – Jimmie Johnson will be in the Kobalt Social Media Command Center in the Neon Garage at 1:45 pm. The Team 48 crew will join him at 3:15 pm and all will be live tweeting this afternoon’s race @LowesRacing.

10:40 am – The practice session ends without further incident. Kasey Kahne is fastest at 188.134 mph. Greg Biffle, Kyle Busch, Kevin Harvick and Carl Edwards are second through fifth on the speed chart.

The teams will have almost an hour to make adjustments for the final practice session from 11:30 am to 12:30 pm.

10:30 am – The Cup Series drivers are on track. There was a brief caution five minutes into the session for David Reutimann’s spin but we’ve been green since then. Kasey Kahne is fastest with 10 minutes remaining in the session.

9:30 am – The Nationwide practice session is over. Austin Dillon was fastest with a lap of 179.647 mph. Brian Vickers was second, followed by Sam Hornish, Trevor Bayne and Brian Scott.

Bliss will get a chance to race after all. He’ll borrow a backup car from teammate Eric McClure to replace the one he crashed early in the session.

8:40 am – The track is under green flag conditions for the first time since Thursday and the Nationwide drivers are experiencing their first laps at speed.

And 4 minutes into the session we’re under caution for a crash involving Mike Bliss and Scott Lagasse coming off Turn 4. Bliss' team does not have a backup car so they are done for the weekend.

8:00 am – Good morning from Las Vegas Motor Speedway, where it’s still cloudy but there’s no rain and the track is almost dry.

Despite the heroic efforts of the speedway staff, yesterday’s rain wiped out any activity on the track and cancelled qualifying sessions for today’s Sam’s Town 300 and tomorrow’s Kobalt Tools 400.

With the Nationwide Series grid filled according to the rulebook and no track time before the cancellation, the field is set at 40 starters and that means Chase Miller, Kevin Swindell and Las Vegas’ own Brendan Gaughan will not get to race this weekend.

Brian Vickers leads the field to green in the Joe Gibbs Racing No. 20 Toyota. Trevor Bayne starts next to Vickers with Brian Scott, and Austin and Ty Dillon rounding out the top five. Phoenix winner and Las Vegas native Kyle Busch starts 23rd in another Gibbs Toyota. Dale Earnhardt, Jr starts 32nd, one spot ahead of his nephew Jeffrey Earnhardt.

The Nationwide Series teams will be on the track as soon as it is ready. Shouldn’t be too long now…
