The two-time champion Coco Vandeweghe defeated Arantxa Rus 7-6(4) 6-3 to clinch the quarter-finals for the fourth time at the Libéma Open. .The American, who lost in the first round last season, won the title in 's-Hertogenbosch in 2014 and 2016.
She needed to fend off a solid performance by Rus and fired 26 winners, including 11 aces, and 23 unforced errors. Vandeweghe reeled off the first seven points of the match against Rus who did manage to beat her in the qualifications at the Libéma Open in 2011.
The Dutch rebounded from an early break down to force a tiebreaker but she critically double faulted at 4-3. An unreturned serve and the seventh ace gave Vandeweghe the last two points and made her seal the fourth tiebreak out of six she has played so far this season.
After an exchange of breaks in the opening stages of the second set, Rus sent a backhand wide to offer Vandeweghe a break to love at 5-3. She soon surrendered to the 11th defeat in 13 matches against a Top 20 player. Vandeweghe, who sealed the 8th win of the year with the 11th ace of the match, the 69th in 2018 will meet her compatriot Alison Riske or the Hungarian young talent Fanny Stollar.
Aleksandra Krunic completed the 21st overall win on grass and reached at Libéma Open the third quarter-final of the season. The Serbian, seventh seed in Rosmalen, defeated 7-5 6-2 the Dutch wildcard Bibiane Schoofs, in her maiden performance at WTA level since 2011 after a long gap due to injuries and private matters.
Krunic will meet Veronika Kudermetova who reached the first WTA quarterfinal of her career with a 6-2 2-6 6-3 win over Belinda Bencic. The Swiss came off two difficult months, as she had to practice with no weight on the foot.
As she confessed to WTA Insider, she tried to keep fit, do the bike, core exercises, but since the week before Roland Garros, she's practicing normally. "I'm looking out for my body but I'm trying to get fit and trying to get the match play.
That's the first thing that goes away, the eyes, the timing. That's really tough. You can only get it back in matches. In practice you cannot simulate it" she admitted after her first-round win. Viktoria Kuzmova claimed the tenth win in last 12 matches played as she defeated the No.6 seed Alison van Uytvanck 3-6 7-6 (4) 6-2 victory.
The 20-year-old Slovakian managed to celebrate her 11th win in 20 matches against a Top 20 player as she came back after losing the first set for the third time this year. The Belgian, who beat Kuzmova in the semifinal clash in Budapest earlier this season, was up a break in the second at 2-0 but the Slovakian extended to 10-4 her win-loss record in tiebreaks in 2018 and the momentum shifted.
Thanks to her eighth overall win on grass in ten matches, Kuzmova awaits in the quarterfinals the No.2 seed Elise Mertens or Antonia Lottner.
