6:40 p.m. -- Comments from Brian Vickers, who finished third in Saturday's Sam's Town 300:

"It was pretty wild. I think I spent more time avoiding crashes myself than anything else. You're going to have that. These cars are fun to drive, but you have to drive them so hard. They are practically running wide open around here. You have to constantly loosen them up and loosen them up to try to run wide open and it's just going to happen. I'm really proud of the Dollar General guys; we had a great car. Unfortunately, we made a mistake on pit road, left a lug nut loose, otherwise I think we had a shot at the win. We had a really, really good car the last two runs. We were just fighting back for track position.

"All the fast cars were having problems and a lot of them were just crashing. It's tough with these cars. I don't think it's anyone's fault -- I'm not trying to say anything bad -- it just is what it is. You're out here at this track trying to run wide open and you constantly try to free it up and free it up so you can keep your momentum up so you can run wide open -- that's going to lead to problems. That's why you saw a lot of the crashes, I believe. When it comes to the pit road instances, like us missing a lug nut, I don't know what was going on there. It just seemed like everyone who got in the lead had a problem."

6:20 p.m. - Comments from Carl Edwards, who finished second in Saturday's Sam's Town 300:

"That was a wild day. We had a great racecar; the car was real fast. There were a lot of wrecks. The deal is, these cars have so much downforce and not a lot of power and the track's so fast it's like a slot car. You've got the throttle down and you're bound down in the corner and if anything happens, if someone gets you a little loose, it's really hard to correct. A lot of cars wreck because of that today.

"We had a tire go down, we got a speeding penalty and all sorts of things happened but we were really fortunate and luck was on our side and we had a chance to go out there and race for the win. I just didn't drive it in deep enough under Greg (on the last lap) because he could hang on the outside of me and he got me real loose there and I thought for a second it was going to be a disaster. It ended up we had to back up and we finished second. Man, I really didn't want to finish second but that's a great points day for us - that's the only consolation.

"For a win, we all race really hard. Greg would race me extremely hard and I do the same with him. You just want to race as hard as you can without causing a problem because right now, we're 1-2 and we could have been backed into the wall and that would be really bad. In a way, you race your teammate maybe a little differently but more than that, you're able to swallow it, if he beats you, a little more. It's not that you race him differently it's just that you can kind of accept it if he beats you."

6:05 p.m. - Comments from Greg Biffle, who won Saturday's Sam's Town 300 NASCAR Nationwide Series race:

Greg Biffle: "It was certainly an eventful day. I'm feeling a little under the weather for starters. Then we got caught speeding on pit road. I thought I had the RPM pegged on what we thought pit-road speed was but obviously we were one mile an hour over. The car was just so fast, we were able to drive right back through the field and work our way back to the front.

"I had a little (fuel) pickup (problem) on a pit stop and lost a spot. And then we ran out of gas there, which was kind of unexpected. It was pretty much out of gas coming out of (turn) two so I shut the engine off and coasted around and got the thing running at pit road speed to coast into the pit box. It worked out perfectly - it just had barely enough fuel to get it going after they plugged the gas in.

"It was a great day. The guys did a good job getting the car prepared and Citifinancial has stuck with us through tough times and there were a lot of fans here today. I was pretty happy to see how many fans were in the grandstands. I think it was a pretty good success all the way around."

5:04 p.m. - Greg Biffle edges Carl Edwards and wins the Sam's Town 300 NASCAR Nationwide Series race. Brian Vickers is third, Jason Leffler is fourth and Dale Earnhardt Jr. finishes fifth. Stay tuned for comments from the top drivers.

3:35 p.m. - At the halfway point of the Sam's Town 300, rookie Justin Allgaier is the leader in the No. 12 Verizon Wireless Dodge. The race is under caution, the eighth of the afternoon.

2:30 p.m.- Kyle Busch and Scott Speed talk about the incident on lap 22 that sent both drivers to the garage:

Kyle Busch: "It was a mistake on my part battling for the lead that early in the race. I just should have known, that as good as this Z-Line Designs Toyota was driving, to just ride. Trying to get on the inside of (Kevin) Harvick there and got all the air taken off my side and spun out. It was 100-percent my fault trying to race for the lead."

Scott Speed: "It was a racing thing, you know. I think the 18 (Busch) spun out, being pinched down by the 33 (Harvick) on the bottom. We were just in the wrong place at the wrong time. At least we were fast. The car was running good. We were really tight at the beginning just to stay in the lead but it was coming together and I think we were going to have a really good car today. But it happens."

2:10 p.m. - The race is halted under a red flag after Kyle Busch spins coming out of Turn 4 and slides up into pole-sitter Scott Speed. Several cars, including Brendan Gaughan, spin trying to avoid the wreck. Track workers are busy cleaning up the debris and fluid on the track. Busch was taken to the infield care center, evaluated and released.

1:52 p.m. - The first caution of the Sam's Town 300 comes out on lap 7 when Denny Hamlin spins coming out of Turn 4. As the cars check up, Mike Bliss makes contact with Brad Keselowski and Keselowski hits the outside wall. Keselowski has heavy front-end damage. Brendan Gaughan, who started at the rear of the field, has raced his way to 12th place.

1:20 p.m. – Some quick facts about the Sam’s Town 300 at LVMS: No driver has participated in all 12 Las Vegas races. Jason Keller has raced in 11 of the 12, the most of any driver. ...

The deepest in the field a race winner has started was 29th by Joe Nemechek in 2003. ... Jeff Burton and Mark Martin are tied with three Sam’s Town 300 victories each.

NASCAR Sprint Cup Series practice is underway right now and the Sam’s Town 300 will begin at 1:30 p.m. (PST).

10 a.m. – Brendan Gaughan will start at the rear of the field for today’s Sam’s Town 300, but the driver of the No. 62 South Point Hotel and Casino Chevrolet couldn’t have been happier as he reflected on the events of the past 20 hours. 

After leading the first practice session yesterday, Gaughan spun and hit the wall between Turns 1 and 2 during the second practice and his Rusty Wallace Racing crew was forced to pull out Gaughan’s backup car for this morning’s qualifying session. Despite having to race a car in which he was unable to practice, Gaughan is eagerly awaiting today’s 200-lap race. 

“The neatest thing about where I’m at right now is confidence in your team,”Gaughan said after his qualifying run. “I remember back in 2003 with our (Orleans Racing Truck Series) team, it didn’t matter what truck it was, we were strong. Our primary car here was the fastest thing on the track. We pulled the backup out, hadn’t had a lap on it, and it feels so good to know that when you pull a racecarout that you’re not scared of it. 

“All the guys worked late last night and early this morning getting this (backup) car ready. When you have something that’s that similar, it works. When I went out to qualify, for the first time in years I had the confidence to say I wasn’t worried.” 

Gaughan said his approach to today’s race is simple. 

“I’ve won from the back in Texas twice (in the Truck Series),” he said. “My thought is I’m in Vegas, I know I have a great racecar, Rusty Wallace and Chevy have given me great equipment ... let’s just pass people on the outside and go to the front.”

9 a.m. – Good morning from Las Vegas Motor Speedway where race fans are in store for another great day. Once again, the sun is shining and the temperature is expected to climb to 70 degrees for today’s Sam’s Town 300 NASCAR Nationwide Series race. Qualifying for today’s race is expected to begin shortly. Check back here often, as we’ll be updating this blog throughout the day with news, stats and driver interviews.
