Re: Who will be the next to complete the career Slam?
Kerber - not winning RG anytime soon unless she makes the F and plays a nervous Serena in the final.
Muguruza - possible if she can get her shit together, I still have confidence in her especially since she got rid of Sumyk.
Kvitova - as much as I want her to I think she won't win RG to do it. Probably another AO/W before she ends her career.
Osaka - you never know with her but I think she would do it, maybe another 5 more years though.
Halep - probably the best chances. I can see her winning USO this year especially if all the top players flop again.
So, Halep > Muguruza > Osaka > Kerber > Kvitova
