Rain began falling at IMS approximately 15 minutes before the start of the MotoGP practice session, reminding riders of the wet conditions they experienced at IMS on Friday and Race Day of the inaugural event in 2008."This was a very good start to the weekend, and in wet conditions we are looking in good shape," Pedrosa said. "It was raining for the whole session, and we had good grip even though there were some big patches of standing water around the track. I felt confident and was able to push hard, and actually it’s been a quite long time since I’ve felt that confident in wet conditions and been happy to push to the maximum. If it’s dry tomorrow, that’s also good for us, even though the only thing we can really take forward from today’s session is the gearing information."Weather for Saturday’s qualifying and Sunday’s second-annual Red Bull Indianapolis GP is forecasted for dry conditions and mild temperatures.

He was mid-pack through most of the one-hour session and dramatically jumped to second on his last high-speed lap."Obviously, I need dry setup time, but we were up front so I felt quite good," Hayden said. "The team did a good job and made a couple of changes on the front suspension that allowed us to turn a lot better. It was slippery and then quite technical because parts of the track was wetter than others. If I get a good result, I don’t care if it snows."In his first year with Ducati, 2006 MotoGP World Champion Hayden has struggled and considered Friday’s result a nice boost."It’s been a hard season for me; everybody knows that I’ve had big crashes and not a lot of great results and my job is on the line," he said. "So it is good to come here and man up with it. But I’ve got to do it Sunday. Ain’t nobody going to remember Friday afternoon."Both of the American MotoGP riders were in the top 10 in Friday practice, as Colin Edwards of Houston was eighth at 1:53.128 on the No. 5 Monster Yamaha Tech 3."You know, we had a hurricane here last year," Edwards said.
