First up, we've got this rematch. It would be great if Elena were fully fit and able to compete at a top level, but based on what I saw against Caro on Tuesday, that looks doubtful. She said after the match that it wasn't her ankle but the heat that was affecting her. Either way, she did not look great on Tuesday.
Let's go, Sammy! Win and clinch not only your group but a year-end top 5 ranking.
And in the nightcap we have a rematch of the RG quarterfinal, where Fran really started her remarkable run by busting Caro 2 and 3. Fran leads the H2H 2-1, but Caro won their last hard court meeting this year in Montreal fairly easily. If Caro wins, she'll clinch the year-end ranking. If Fran wins, well, she'll be awesome and the WTA's collective foreheads will hit the desk.
The most anticipated match of the day for most will be Vika vs. Kim. Vika is 0-1 after losing to Bepa in straights. Kim is 1-0 after beating JJ in straights. Needless to say, this is a must win for Vika and it will be a good test to see where Kim's game really is.
This one's a toss-up for me, but I'm going with Kim. She leads the H2H 2-1 with both wins coming on hardcourts.
