Re: Grand Slam debutantes
OP: edited to add info about Hrdinova's debut at Wimbledon. I'll see if I can begin editing in updated info on the other player's career best rankings and about those who made their career best performance at this year's Wimbledon as well.
USO entry list is out and there are no debutantes in the MD list. Lapushchenkova may still make it in, though.
