The womens season finale begins Sunday, and Serena Williams second-straight withdrawal from the WTA Finals could give the field much more hope.So who will prevail? Our experts answer a few pressing questions heading into Singapore (coverage begins Sunday on ESPN3).Is Angelique Kerber ready to win a first WTA Finals title?Peter Bodo: Theres no doubt that after winning two majors and becoming the world No. 1 shes a different player this year. But she has to be mentally drained, and her game has never been very effective on the indoor court in Singapore. (Kerber failed to make it out of the round-robin stage in three previous appearances and goes into this year with a 3-7 overall match record.)Greg Garber: Based on the events of 2016, I think not. She followed up her breakthrough win in Melbourne by losing in the first round at Madrid, Rome and Roland Garros -- to Kiki Bertens. Her Asia swing after winning the US Open has been underwhelming.Johnette Howard: Yes. Shes played only two tournaments since mid-September, so she should be fresh. Also, whatever crisis of confidence she had between winning the Australian Open and US Open should be gone. Two slams and the top-ranking proves youre not a one-shot wonder.Melissa Isaacson: Absolutely. Particularly with Serena out of the picture, Kerber should begin winning the big tournaments with some consistency -- a bugaboo before this year -- even when the others, like the recent Asian swing, arent yielding titles.Which player will most likely surprise you?Bodo: The heart of the batting order are the women ranked Nos. 3-5. Agnieszka Radwanska, the defending champion, is playing well again. Former finalist Simona Halep is opportunistic and can salvage a so-so year with a strong performance. But the surface suits US Open runner-up Karolina Pliskovas serve-based game, and if shes on, its going to be tough to stop her.Garber: Radwanska is your defending champion and she typically finishes the Asian swing with a flourish. But Halep, who has improved under coach Darren Cahill, made the final two years ago and she could finish the season with a strong run at Singapore.Howard: Madison Keys had to play her way into the WTA Finals while being on the bubble. She should be match sharp and the courts suit her fast-paced game.Isaacson: Radwanska advances to the quarters or better in all four Slams this year, and she was the WTA Finals champ last year. Let us not forget that the world No. 3 was in position to take the top spot going into the US Open. She has also been the best player on tour since the US Open.What does it say about Serena Williams that she pulled out of the year-end championships for the second straight year?Bodo: If ever proof was required that Serena Williams cares only about Grand Slam titles and her personal comfort zone when it comes to scheduling, we now have it. And at the age of 35, with her record, she really is entitled to do anything she pleases, even if the WTA Tour is disappointed by her indifference to all but the majors.Garber: You could see this one coming. There was a general feeling last year that shutting it down after the US Open stalled Serenas momentum into 2016. Well, it looks like it will happen again, giving the rest of the womens field an advantage.Howard: Serena claims shes still suffering from a shoulder injury and she seems to be following up on her remarks that shes tired of playing hurt and -- the insinuation is -- losing to people that shouldnt beat her. When, and if, she comes back healthy, we can better judge whether age is creeping up on her or shes just been physically compromised.Isaacson: This is what happens to most athletes at the end of their careers, even when they are superhuman athletes with unprecedented longevity like Serena. The injuries are more frequent or simply harder from which to recover. She said her doctor insisted on it. Good move.So, who will win the Singapore title?Bodo: Kerber is probably spent, and with the No. 1 ranking locked up, there is no great incentive for her to finish with a flourish. In round-robin play, you can afford to have an off day, which is a great advantage for an erratic newbie like Keys, who will go on to win it all.Garber: Im going with Pliskova, the revelation at the US Open. Like her game and poise.Howard: Radwanska has been the tours hottest player on the Asian Tour, but shell likely have to get by Kerber, who should be fresher than shes been in months.Isaacson: Kerber, not because she is the hottest player, but because she is the best. Assured the year-end No. 1 ranking after Serena withdrew, there should be no pressure other than to establish herself as the top player in the womens game.
