7:00 pm – That will do it for this weekend’s coverage of the Sam’s Town 300 and the Kobalt Tools 400. Congratulations to our winners Sam Hornish and Matt Kenseth and thanks to all for joining us!

6:52 pm – Joe Gibbs Racing crew chief Jason Ratcliff made an aggressive call on pit road during the fourth caution of the race. With most teams opting for two tires, Ratcliff called for just enough fuel to make it to the end. That kind of call is what has Kenseth so excited about his future with the No. 20 team. “I was grinning inside as I was leaving pit road,” said Kenseth. “I heard him counting under his breath. I thought, oh, I thought he was filling it up. I left pit road and I was, like, that’s what you like. You’re hoping, dreaming, all that stuff, to work with somebody that doesn’t only prepare race cars to win races but you want to call races to win races and do pit stops to win races and adjust cars to win races and be aggressive.”

According to Ratcliff, Kenseth’s desire to stay up front made the decision a no brainer. “(We knew we would pick up a little over a second if we don’t take tires,” he said. “Or we can take right side tires. If there’s going to be some more cautions later in the race, that’s probably going to be the right call. Then when Matt came on the radio – I wasn’t sure how you’d feel about it. He said, ‘Man, just keep me up front.’ I said, ‘Okay. Game on.”

6:45 pm – Jimmie Johnson held onto the points lead after his 6th place finish. He is 5 points ahead of Keselowski, who jumped past Dale Earnhardt for 2nd. Kenseth’s win moved him from 18th to 7th while Kane leapt from 31st to 14th. Kyle Busch had a the second biggest point gain as he jumped 16 positions to 17th.

6:15 pm – Kyle Busch overcame a speeding penalty during his first pit stop to finish 4th at his home track. “I made a mistake and got us mired back in traffic but we fought hard,” said Busch. “We battled back up through there. We’ve got to figure out how we can make these race cars last longer on the long runs for me. Kenseth there was pretty good and he stayed good throughout the long run. We went to hell in a hand basket there after a minute.”

5:35 pm - Brad Keselowski is trying to put his third consecutive top-five finish in perspective but the defending series champion has gotten used to winning and is not willing to settle for anything less. “I’m not happy with top 5s,” said Keselowski, who led 12 laps. “I’m sure when I get home tonight I’m going to go home and throw around some pillows and punch some things because we had a shot at winning all three races and come up short. Whether it’s circumstances or bad luck or today just a little bit of execution. I wanted to win all three of these races and I’m not happy unless we can do that.”

5:11 pm - Kasey Kahne, who led six times for 114 laps, was battling Kyle Busch for the lead when the fourth caution flag flew for fluid from Joey Logano’s Ford. Kenseth took the lead after pit stops with fuel only strategy.

Kahne did everything he could to pass Kenseth but settled for second. “We had two cycles on left sides,” Kahne explained. “Matt did everything right. This is not the guy you want to have to race with 10 to go because he’s going to do everything right. He did a perfect job and we came back second.”

4:02  pm – Matt Kenseth’s win in the Kobalt Tools 400 marked just the third time in series history a driver has celebrated a birthday with a trip to Victory Lane. Cale Yarborough did it once and Kyle Busch has done it once. “I was kind of bummed out about being 29,” joked Kenseth, who turned 41 years old today. “Since we’re standing here with a win, I’ll take it.”

It took Kenseth just three races to record his first win with Joe Gibbs Racing after switching teams during the off-season. He led twice for 42 laps and held off Kasey Kahne to post his third series victory at LVMS. “This is awesome,” said Kenseth. “I feel really good about this group. I really feel like this is just the beginning. I was real nervous. All day (Kahne) had the best car. I just had to make sure I stayed in front of him. Didn’t have quite the fastest car there at the end, but we had it where it needed to be.”
