Okay, Tsonga has just beaten Blake, meaning Del Potro is now the 7th qualifier for TMC, and this is relevant for tomorrow's "winner takes all" match:
the final = Tsonga #7 for TMC
; Simon is #1 alternate; Blake #2 alternate; (Nalbandian #3 alternate)
the final = Tsonga DOES NOT
qualify - #9; (Nalbandian qualifies by right, at #7)
; Tsonga is #1 alternate; Simon #2 alternate; Blake #3 alternate.
Either way, it looks good for Jo (#8, for tonight), now...even if he doesn't win tomorrow, if Dave keeps his word (that he isn't going to Shanghai), Jo is first in line to take his place.
