Meh. Groth painted the lines on his volleys at the end of the third to not get broken, and Fed played a horrible TB, with a double and then having 4 good looks on Groth's serve to pass and he didn't even put one on the court.
Regression in terms of the ball striking though, hopefully that was just because of the style of tennis.
Re: Wimbledon R3: Federer d. Groth 6-4 6-4 6-7(5) 6-2
15 minutes of Groath from 5-5 in the third, other than that nothing to see. Good last game from Fed though, amends himself for his very average start in the last set (despite the early break, Groth was just worse). R4 vs RBA still as NID as it gets anyway.
