Rafa doesn't need to be any more competitive, he had 5 break points in a game in the 2nd Set and was up a mini-break in the tiebreaker before Djokovic's shot hit the top of the net and bounced over Rafa's head.
Rafa should just repeat that 2nd Set every time they play, and he'll win all their hardcourt matches.
Plus Rafa lacked energy, so can do even better than that

Then again, do hardcourts even matter? Despite all this dominance on hardcourt, Djokovic only has 16 slams, and only leads Rafa 29-26 h2h, and they are 3-3 in their last 6 meetings.....and Rafa leads 9-6 at slams and has a winning record over Djokovic at Roland Garros and US Open.
So whatever hardcourts are doing for Djokovic, is simply not enough.
