Djokovic' on-grass win rate is at 85.83% and then from the active players who are going to play Wimbledon the next one is Bautista Agut with 69.59%. After that come Gasquet and Kyrgios and considering how strong Djokovic is right now, he is well set to increase his GS title count further this year. I guess only some kind of black out could stop him.
as it looks now, this season look as better chance for Djokovic to win all GS's than in 2021, when he lost final to Medvedev at US Open
and on Wimbledon, looking at form and participants, he is a main favorite, really can't see who can win over him in London
maybe there will be a surprise, but doesn't look were likely to be honest, it is just that he will probably not play any tournament on grass before Wimbledon, but he is experienced enough not to lose in first few rounds, no matter opponent
No he won against Berrettini in Wimbledon in 2021 and he also won the Australian Open and the French Open, but did lose against Medvedev at the US Open. So in total that was three GS titles in 2021. He also won three in 2011 and in 2015 and now I think it is very possible that he will take him all four GS titles. He won on clay now and he doesn't have any weaknesses in the sense that he is "bad" on any surface. Grass is his strongest surface and if he doesn't get an injury I can't think of anyone to stoP him unless he has a very bad day and that doesn't happen very often. On hard court his win rate is about as good as on grass and I am getting the feeling that he will keep adding titles for a while now. Alcaraz said he was injured at the French Open but he is playing again already. I think that he was puzzled by the strength of Djokovic because even when he won the 2nd set it was insane how he had to play to even win that set. It is humanly not possible to keep such a performance for five sets usually. Even when he hit every ball perfectly he was far from winning the point.
