Vital MX Pit Bits: 2008 Rockstar Energy U.S. Open, Day 2 3

Click the following link for the latest news, along with a 15-photo gallery covering Saturday's pre-race action in the pits from the Rockstar Energy U.S. Open, at the MGM Grand Garden Arena in Las Vegas.

Here are the top ten times from Saturday's practice sessions.

1. James Stewart (Yamaha) 42.621

2. Ryan Dungey (Suzuki) 43. 005

3. Chad Reed (Suzuki) 43.395

4. Andrew Short (Honda) 43.431

5. Broc Hepler (Yamaha) 43.648

6. Nico Izzi (Suzuki) 43.708

7. Justin Brayton (KTM) 43.871

8. Tommy Hahn (Kawasaki) 44.017

The track was rebuilt overnight, and then watered much more substantially than on Friday, when it was dry and slick.

Tonight's racing should be interesting, with James Stewart on pace to take home $250,000, and a fast Ryan Dungey, as well as Chad Reed, who may not have a shot at the overall after last night's DNF, but he'll be a threat to win.
