I am really glad he has gather himself together in the middle of second set! Was very off, struggling to put a serve in, but managed to hold few times even when games went to deuce! Last year Grigor would have lost this match 6-3 6-1 something! well done! Benny helped a lot tanking the 3rd set when got a break down, though, but I'll take that!
Brilliant play to get the break in the 2nd and cold head and no nerves to serve it out!
Good luck next round, Grisha!
