MATCH POINTS

Two-time champion CoCo Vandeweghe lifted the trophy in 's-Hertogenbosch in 2014 and 2016, defeating Zheng Jie and Kristina Mladenovic in those respective finals. The American is one of two former champions in the draw, alongside last year's victor, No.4 seed Anett Kontaveit.

As a wildcard last year, Arantxa Rus defeated Timea Babos to make her first WTA quarterfinal in five years - kickstarting a ranking rebound that has seen the Dutch No.2 return to the Top 100 for the first time since May 2013 this week. Rus is 0-3 against her opening opponent, Ekaterina Alexandrova, with all their encounters coming in German clay ITF events. The Russian took three-set victories in Wiesbaden and Versmold in 2014, and won in Essen the following year via retirement.

Carina Witthoeft will seek to snap a six-match losing streak today - but her opponent, wildcard Bibiane Schoofs, is a player who inflicted one of those losses on her. Schoofs, playing just her second ever WTA event at the age of 30 following Luxembourg 2011, where she made the quarterfinal, defeated the German 6-3, 6-4 in the Cagnes-sur-Mer ITF $100,000 event last month.

CoCo Vandeweghe's first-round match against Aliaksandra Sasnovich is a reprise of the third rubber of last year's Fed Cup final. With the tie poised at 1-1 in Minsk, Vandeweghe won 6-4, 6-4 to put the USA 2-1 up on Belarus, paving the way to an eventual 3-2 victory.

No.6 seed Alison Van Uytvanck has a 2-0 head-to-head record against Richel Hogenkamp, with both matches being played on indoor hard courts. The Belgian defeated Hogenkamp, who is coming off a three-set loss to Maria Sharapova at Roland Garros, 6-2, 7-6(4) in Luxembourg in 2015 and 6-3, 6-7(4), 6-3 two years later in the Poitiers ITF $100,000 tournament.
