Truth be told, I'd be extremely surprised if Bottas could beat Hamilton often. The Boss' poor performance might have been due to car damage alone or to one of his off days, which we know he has, but so far we haven't seen anything that suggests that Bottas can keep a high enough level to consistently equal Hamilton, let alone beat him. A single race in which Hamilton took pole and had some sort of justification for being slow in the race (car damage) is not by any means indicative of a change of trend.
