ST. PETERSBURG, Russia/KAOHSIUNG, Taiwan – The St. Petersburg Ladies Trophy and the Taiwan Open are new additions to the WTA Calendar, the former headlined by top seed Belinda Bencic and former No.1s Ana Ivanovic and Caroline Wozniacki, while Venus Williams leads the field in the latter.

Bencic is coming off of her first career fourth round appearance at the Australian Open, and with few points to defend until the grass court season, the young Swiss Miss will be aiming to make the Top 10 debut that narrowly eluded her at the end of 2015.

Granted a first round bye, Bencic will face stiff opposition from the get-go, as she plays the winner of the first round encounter between Annika Beck – who also reached the fourth round in Melbourne, falling to eventual champion Angelique Kerber, or Lucie Hradecka. The high seed in her quarter is hometown favorite and No.5 seed Anastasia Pavlyuchenkova, who has played well in Russia, having reach the final of the last two Kremlin Cup tournaments – winning in 2014.

A potential semifinal opponent for Bencic is No.3 seed Caroline Wozniacki, who took a late wildcard in the hopes of kick-starting her 2016 after a surprising first round loss in Australia. Things might not get much easier for the Dane, however, as she could face former Top 10 player Dominika Cibulkova in the second round. No.7 seed Kristina Mladenovic, currently playing Fed Cup in Marseille, is her projected quarterfinal opponent, should she get past either 2013 Wimbledon semifinalist Kirsten Flipkens or rising Russian Daria Kasatkina – who made a second straight Grand Slam third round in Melbourne.

No.2 seed Roberta Vinci and No.4 seed Ana Ivanovic flank the bottom half of the draw – Ivanovic could play another one of the young Russians, Margarita Gasparyan, in the second round – Gasparyan fell to World No.1 in the fourth round of the Australian Open – and is slated to face No.8 seed and Hobart International champion Alizé Cornet in the quarters. Vinci opens against either Jelena Ostapenko or Yanina Wickmayer, and could play No.6 seed Anna Karolina Schmiedlova in the last eight; Schmiedlova had an impressive summer swing in which she made her first career Premier quarterfinal at the Western & Southern Open as a qualifer.

Over in Taiwan, the elder of the Williams sisters has no first round bye in this 32-player draw, and opens against local wildcard Lee Pei-Chi. In an interesting quarters that features names to watch like Donna Vekic and Anastasija Sevastova – a former No.36 who made her return to tennis following a brief retirement at the start of 2015 – Williams could face fellow American and No.8 seed Alison Riske in the quarterfinals. No.3 seed Yulia Putintseva is also coming off a solid run at the Australian Open – beating Wozniacki en route to the third round – and is Williams’ projected semifinal opponent. The two played a rousing first round at Wimbledon last year, with the five-time champion coming out on top, 7-6(5), 6-4.

On the bottom half of the draw is the talented Japanesewoman, Misaki Doi, who held a match point against Kerber to start the Australian Open. Doi will open against Kristyna Pliskova, who hit a record number of aces in Melbourne, and could play No.7 seed and countrywoman Kurumi Nara in the quarterfinals.
