SINGAPORE - The White Group will take center stage on Monday at the BNP Paribas WTA Finals Singapore presented by SC Global. Who will take the upper hand and move to the top of the standings? We preview the action.
Monday, White Group
 Agnieszka Radwanska (POL #3) vs.  Svetlana Kuznetsova (RUS #9)
Head-to-head: Kuznetsova leads, 12-4
Key Stat: Radwanska won her first WTA Finals title in 2015 and became the first player from Poland to ever achieve the feat.
No time for jet lag for Russia's Svetlana Kuznetsova. The 31-year-old stormed to the Moscow title on Saturday to squeeze in as the last elite eight qualifier, and on Monday she'll make her first appearance at the WTA Finals since 2009 against defending champion Agnieszka Radwanska. In five previous WTA Finals appearances Kuznetsova has never passed beyond the round-robin stage (3-12) but there's an air of possibility surrounding her as she continues with an improbably good campaign that has seen her log 43 wins and return to the Top 10 for the first time since 2010. But how will she handle the challenge of facing a fresher Radwanska after logging 5,000 frequent flier miles after a long weekend in Moscow? Working in the Russian's favor is the fact that she's dominated the lifetime head-to-head with Radwanska, winning 12 of 16 including eight of the last nine. But working against her is the fact that the pair's last three battles have gone three sets and Kuznetsova had to save a match point in Wuhan to defeat Radwanska in their only meeting of 2016. Radwanska comes in hot, having won eight in a row and 19 of her last 22, and she's excited to get her title defense off on the right foot.
"There is always a little bit more pressure when you really have to defend a big title, a lot of points," Radwanska said on Saturday while addressing reporters at All-Access Hour. "But on the other hand, when you're Top 5, Top 10, you're pretty much defending every week more or less. So just trying not to really think about it and of course just try to repeat what I did last year."
Pick: Radwanska in three
 Karolina Pliskova (CZE #5) vs.  Garbiñe Muguruza (ESP #6)
Head-to-head: Pliskova leads, 3-1
Key Stat: Muguruza went 3-0 in round-robin play in her Singapore debut last season, but lost to Radwanska in the semifinals.
Daunting power and daring shotmaking will be on display on Monday at Singapore Indoor Stadium as two feared and ferocious phenoms will renew their budding rivalry. Karolina Pliskova owns the 3-1 edge in the lifetime head-to-head against Garbiñe Muguruza, but it is the Spaniard who claimed the biggest prize in 2016 by winning her first major title. That's something that Pliskova has yet to do, but the Czech No.1 did come close at this year's U.S. Open when she reached the final and fell in three sets to Angelique Kerber in a thrilling title tilt. The fact of the matter is that both players have extremely bright futures, and each is hungry to prove their big-match potential once again here in Singapore. Pliskova, who is making her WTA Finals debut, defeated Muguruza this year in Cincinnati en route to the biggest title of her career. That title run created a lot of belief for the then unproven Czech, and she comes into Singapore with brimming confidence, a Top 5 ranking and a three-match winning streak against Muguruza. Is the time now for the 24-year-old Czech to impose herself on a star-studded WTA Finals field, or will experience pay off for Muguruza in her second consecutive trip to Singapore?
Pick: Muguruza in two
By the Numbers:
8 - Radwanska is now tied with Maria Sharapova for second on the all-time WTA Finals appearance list with eight.
0 - A Spaniard has never won a WTA Finals title and only one (Sanchez-Vicario, 1993) has reached the final before.
18 - Number of players that have advanced to the semifinals with a 3-0 Round Robin record. Seven have gone on to win the title.
9 - Radwanska leads all participants with nine career WTA Finals wins, but Muguruza is the only player in this year's field to enter with a winning record (3-1).
