Petra falls to Kerber in opener

Three days after their Fed Cup clash on this very court, two-time Grand Slam champion Angelique Kerber turned the tables on former World No.2 Petra Kvitova, securing a 6-3, 6-2 victory to keep her hopes of a third Porsche Tennis Grand Prix title alive.

Kerber had won just four games against Kvitova during last weekend’s Fed Cup semifinal against the Czech Republic, and appeared eager for revenge from first ball, navigating through some tough opening games to grab the only two breaks to take the early advantage.

Back-to-back champion in Stuttgart between 2015 and 2016, the German took another big lead in the second set, securing victory on her third match point after one hour and 17 minutes on court.

Kvitova employed her aggressive game throughout, but was undone by 32 unforced errors compared to 28 winners; Kerber, by contrast, converted four of six break points and saved all three break points faced on her own serve. // Photo: Alex Grimm/Getty Images Europe
