capriati will put up a fight for sure, but unfortunately for her fighting isn't the issue, but closing out a match. She has struggled against all the top 6/7 players all year.
At the USO, I though Juju should have won that first set, remember she was up 4/1 before the crowd got to her, lucky for her it was early in the match and had time to regroup
Difficult to say at this point who would come out on top, depends on how exhausted Justine is and how she copes healthwise.
Rena- a tennis great! 22 at striking distance.
