No.3 seed Katerina Siniakova faces Anhelina Kalinina for the first time since the pair's junior days. In their only previous meeting, Siniakova was a 6-2, 6-0 victor in the third round of the Osaka Grade A junior event in 2012 en route to winning the title.
No.7 seed Tatjana Maria is 1-0 against wildcard Jana Fett, having defeated the Croat 6-2, 7-5 in Toronto qualifying in 2017. Fett is playing her first WTA main draw since Tashkent last year.
Former Top 20 junior Kamilla Rakhimova makes her WTA main draw debut today via wildcard. The Russian has compiled a 39-11 win-loss record in 2019 so far, winning four ITF World Tour titles - including two at W25 level in Andijan and Fergana - and raising her ranking from World No.890 at the end of 2018 to World No.306. Rakhimova plays fellow wildcard Diana Marcinkevica for the first time; the Latvian is competing in her third WTA Tour main draw, having qualified for Stuttgart in 2014 and been a lucky loser in Strasbourg this May, and is still looking for her first win.
In qualifying, an all-Austrian derby finds Barbara Haas battling Julia Grabher. The compatriots' head-to-head is tied at 2-2, with Haas taking the first two meetings in home ITF W10 tournaments in 2014 and 2015, and Grabher levelling the series with two ITF W25 wins in 2018 in Sao Paulo and Leipzig.
