Novak Djokovic has eased into the semi-finals of the US Open in New York following a walkover victory against Jo-Wilfried Tsonga, who called the match after just 81 minutes due to an injury to his left knee.
It's the world number one's third walkover in five matches at this year's tournament, and many on Twitter were quick to point out how easy his path to the last four has been.
Djokovic himself has also acknowledged this trend and has said that he is close to his peak heading into the final rounds at Flushing Meadows.

Speaking after the match, the Serbian said: "I got a lot of days off and recovered my body.
"Right now I'm feeling very close to the peak. That's the position where I want to be. This scenario was ideal at this stage. I'm reaching my peak in terms of my form."

Djokovic has been nursing a couple of injuries himself, and began the tournament having problems with his left wrist and right elbow.
Earlier withdrawals from opponents Jiri Vesely and Mikhail Youzhny, however, ensured that the Serbian has had a slight advantage over many of his rivals, and fans on Twitter have weighed in on the tennis stars lucky circumstances.
Djokovic has spent just six hours and 28 minutes on court at the Arthur Ashe Stadium at the Open this year, and will now face Frenchman Gael Monfils in the semis. The number 10 seed beat his fellow countryman Lucas Pouille in straight sets 6-4 6-3 6-3 on Tuesday night.
Compared to perhaps his biggest rival at the tournament in the shape of Andy Murray, who looks to book his place in the last four this week, the Serbian number one has spent far less time on the court.
Murray has already played nine hours and 32 minutes, and still has his quarter-final to play against Kei Nishikori.
Should the Scotsman navigate his way to the final, and both he and Djokovic are expected to, then tiredness could become a factor in the outcome.
Murray's head-to-head record against Djokovic is already pretty poor, with the 29-year-old Serb winning 24 matches to Murray's 10.
However, with Djokovic playing little tennis so far in this tournament, it could be the perfect opportunity for the Brit to build up a good head of steam and blow aside a stuttering Djokovic if the two do meet in the final on Sunday.
