I just realized this through a friend but on June 13th rankings:
5. Tsitsipas 4900
6. Alcaraz 4890
Both players are not defending any Grass tournament points. Basically, whomever does better on the warm-up events between the two players will more than likely be the 4th seed at Wimbledon, and that is HUGE!
In addition, with Djokovic's loss today plus Wimbledon dropping points this year, Djokovic will drop to 4,770 points after Wimbledon tournament. Now, he can play a warm-up tournament before Wimbledon to gain points, but I doubt he will do that.
Those 4,770 points will still be good for a Top 8 ranking for Djokovic.
