Youngest GP winner is the one that really stands out for me at the moment; other stats, not so much.
[Pedrosa] has scored a total of 3011 points across all three classes during his grand prix career and becomes only the third rider ever to pass the milestone of 3000 grand prix points, after Rossi (with a current total of 4604 career points) and Capirossi (3215 career points).
