Wawrinka in his quarter...that's bad!!
Hope he can reach final rounds, or better, win it so he can gain some points and get a reasonable chance of ending the year inside the top 10
I know that many people don't care about ranking, but I don't know, for some reason I do. May be coz it adds to his achievements when he ends many years inside the top 10?!!
Anyway best of luck to David
