MATCH POINTS

Dayana Yastremska is on a seven-match winning streak. The 18-year-old captured her maiden title in Hong Kong on Sunday, won a three-hour opener in Luxembourg on Tuesday over Varvara Lepchenko that finished close to midnight, then turned around to capture her first Top 20 win over Garbiñe Muguruza on Wednesday. Yastremska plays another recent titlist in surging form today - Tashkent champion Margarita Gasparyan.

Vera Lapko takes on Belinda Bencic for the second time in as many weeks today. Last week, the Belarusian triumphed 1-6, 6-1, 6-0 in the first round of Linz. Lapko is playing her third post-US Open quarterfinal following Guangzhou and Tashkent, and is seeking to make her third career semifinal following Lugano in April; Bencic, who snapped a six-match losing streak this week, is bidding for her first WTA semifinal since 's-Hertogenbosch 2016.

Andrea Petkovic dominates her head-to-head against qualifier Eugenie Bouchard, leading 5-1 overall - including a 2-6, 7-5, 6-1 first-round win in Luxembourg in 2013. The German's only loss to Bouchard came in the third round of Wimbledon 2014, and she won their most recent meeting 6-2, 4-6, 6-0 at Washington 2017. Petkovic is seeking to make her fourth semifinal of the season; having reached the last four in Linz last week, a win would also mark the 31-year-old's first back-to-back semifinals since Miami and Charleston in 2015. Bouchard is bidding for her second semifinal of 2018 following Gstaad in July.

No.1 seed Julia Goerges is yet to lose more than three games in a set to Donna Vekic over two previous meetings, having triumphed 6-2, 6-2 in the second round of Budapest in 2017 and 6-3, 6-2 in the fourth round of Wimbledon this year. Goerges, the 2010 runner-up to Roberta Vinci, is the only player remaining who has played a Luxembourg final before.
