Newman got loose near the end of the session going into turn 3 and slapped the wall pretty hard.

“I opened my entry up a little too far. I got a little aggressive and just got loose getting in, and that was it. Our WIX Filters Chevrolet is really good.  I see that (Tony) Stewart is on top of the board now. We’ll just plug-in the same game (to the back-up car), and we’ll be alright.” Newman said.

Shortly before Newman’s accident, Michael McDowell also had trouble going into Turn 3, but he had cut a right-front tire. McDowell will also be going to a backup car.

Stewart, who comes into this race after a disappointing 16th place finish at the Daytona 500, has one victory at this track which he claimed during his rookie season back in 1999. Stewart also has three runner-up finishes at Phoenix where he finished behind Kevin Harvick, Jeff Gordon, and Mark Martin respectively.

Speaking of Mark Martin he was our surprise of the day. Martin was second quickest in his #55 Aaron’s Dream Machine Toyota. It looked like Martin would leave on top of the sheets, but Tony Stewart unloaded his fastest lap just before the red flag flew to end Session 1. Jeff Gordon and Jimmie Johnson are both coming off disappointing finishes during the season-opening Daytona 500. They led 1-2 at the beginning of the session for about ten laps, but the two Hendrick Motorsports teammates ended up 17th and 24th fastest.

Daytona 500 champion Matt Kenseth was tenth quickest just behind his Roush-Fenway teammate Greg Biffle who had the fastest car for the majority of the practice but ended up in third position.

Other notables include: Newman (4th), Kahne (5th), Montoya (6th), Kyle Busch (7th), Logano (8th), McMurray (9th), Edwards (16th), Jr. (31st).

Greg Biffle will be a man to watch on Sunday. Teammate Carl Edwards was just in the media center and noted that Biffle looks like he has a really great car for Sunday. “It looks like Biffle is extremely fast in practice, so we’ll lean on him a little bit.”

Jimmie Johnson knew this was coming, but he got a question from me regarding the penalties. “How much did Knaus’ previous infractions have on the current penalty? His answer: That’d require me to speculate. Take that question to NASCAR.
