Montanes and DGT conciliation match for the real hard court GOAT, lol. Good for DGT to take a set, Wawrinka is rusty.
I can't even say he was rusty, as he bagelled Gimeno-Traver in the 1st Set and also did what DGT did to him in 2nd Set in the 3rd (break once, then break again to win the set). He just needs control on where he allocates his clutch and energy, because it seems he mentally clutches in one set (not only clutch, but win sets in Federer-esqe quick manner) then "tanks" (in a sense that he can't handle doing so much in the previous set mentally) next set, then goes alert again in the 3rd. He has to keep his mental game to the state that made him YE #8 and just go all out come he faces the very top.
EDIT: Interesting trivia: the 1st was actually just 16 minutes -- shorter than the longest service game against Djokovic in the US Open.
