berrettini retired from Queen's Club Championship! The former winner of Wimbledon has not been able to play this tournament.
He never won Wimbledon - he lost in the final against Đoković.
He never even won any Grand Slam (and most likely never will).
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.
