We saw two classic passes from the Repsol Honda rider and it was probably the hardest I've ever seen him overtake people.
The Australian has a bit of a reputation for moaning when people chop him up - most notably also at Laguna Seca in 2008 - so it was good to see him fight back.
It was a nice forceful move past Pedrosa into the Corkscrew, all very fair, and then he pulled off a very brave pass into turn one - a race-winning move - to take the lead from Yamaha's Jorge Lorenzo.
It is very brave to race like that when you are heading the championship because you have a lot to lose. But Stoner had obviously had enough of his points advantage being eroded and decided to get the hammer down.
Spaniard Lorenzo was a wounded soldier after a huge crash on Saturday so he did brilliantly to even be in contention.
I honestly thought his season was over when he hit the ground because it looked like he had broken his leg. His Yamaha team were also very worried.
But he fought back incredibly well to take pole position and then second place. I think he will be very happy with taking 20 points from Laguna.
We have got a three-week break now before the next race in the Czech Republic and it will do a lot of the riders good to nurse their injuries and get back to full health.
We saw another crash for Britain's Cal Crutchlow and his season is really going downhill after such a bright start - it is like James Toseland revisited.
It is almost as if Crutchlow is trying too hard to get back to where he was before he broke his collarbone and it is so easy to make mistakes when you are riding on the limit.
As for whether the Japan GP at Motegi can go ahead on 2 October after the devastating earthquake and tsunami, the preliminary report into expected radiation levels was published on Monday morning, with the official detailed version due to be delivered later this week.
The final conclusion from ARPA, the agency commissioned by the FIM and Dorna Sports SL to do the report, reads: "Based on the estimate dose, it can be said with no doubt that the radiation risk during the race event is negligible."
Before this news was released, I asked team managers and riders what was going on and nobody seemed to know but I can't believe that the race will not go ahead.
A lot of the riders are strongly opposed to travelling, though, so we have a stand-off.
