<p>STUTTGART, Germany &mdash; Petra Kvitova opened her delayed title defense at the Porsche Grand Prix with a 6-4, 6-3 win over Australian Open finalist Jennifer Brady on Tuesday.</p>
<p>Kvitova, who won the previous edition of the tournament in 2019, saved all three break points she faced against Brady to book a second-round meeting with Maria Sakkari.</p>
<p>“It was a fantastic feeling playing on this court again," Kvitova said. "It gave me lots of energy,”</p>
<p>The clay court tournament was called off in 2020 because of the coronavirus pandemic.</p>
<p>Fifth-seeded Aryna Sabalenka needed just over an hour to beat Zhang Shuai of China 6-2, 6-2 to set up a match against Anna-Lena Friedsam, who beat fellow qualifier Ulrikke Eikeri 6-2, 6-0.</p>
<p>Ekaterina Alexandrova rallied from a set down to beat Karolina Muchova 4-6, 6-2, 6-3, and Anett Kontaveit eased past teenage wildcard entry Julia Middendorf 6-2, 6-3.</p>
<p>Kontaveit, who lost the 2019 final to Kvitova, next faces third-seeded Sofia Kenin.</p>
<p>Also, Laura Siegemund won an all-German duel against Mona Barthel 6-4, 3-6, 6-1.</p>
