Casey did a great job on the Ducati!
He rode a pretty much flawles race, its hard to beat someone who makes no mistakes.
He would of had a huge amount of pressure on him too. First ride on the Ducati, first race of the season, first place with a few laps to go, and ontop of all that he had Rossi breathing down his neck!
It wasnt the most exciting of races, but it was great seeing how comfortable he was on the Ducati, and how well he rode it. Nothing Rossi did could force him into a mistake, where as when Rossi got infront he managed to run wide and give the lead back to Stoner...
That Ducati is insanely fast though, apaprently they even brought the rev limiter down to get some more miles out of the tires, not as if they needed too considering he set his fastest lap on the last lap of the race. (ofcourse tyre wear is different when you're leading).
If the motoGP wasnt already interesting enough, i think this season is going to be fantastic

It already looks like the Ducati is the fastest bike out there at these early stages (Rossi was riding the hell out of the Yamaha to make up ground in the corners), will be interesting to see how some of the other manufacturers respond, and how the difference in tyre manufacturers pans out..
(as you could probably tell, i love the motoGP haha)
