A level,maybe even A+ at times,I was/am very surprised and satisfied,when compared to what he played before in RG.
Deep fh most of the time,very smart variation on the BH side(going either deep crosscourt to sod fh or looping it to his BH in order to buy more time to reposition on court),absolutely incredible serving for Rafa's standards,an aggressive attitude when he got a look at the ball and absolutely incredible defense at times.
Rafa would have won either way today. He was too determined,too motivated. He won in three because sod's serve was off and thus half of his game(aces and getting short reply for his fh to put away) was gone and he was forced to trade groundstrokes with Rafa,not the most pleasant perspective,especially when Rafa is not playing short. If Sod's serve had been a bit better,Rafa would have won in four IMO. I also think Robin can't up his level as well in finals as he can in earlier rounds,when there is pressure you can see and feel it in his game.
