Defending champion Anna Karolina Schmiedlova won through to the second round of the Bogota Open, while Sabine Lisicki lost to sixth seed Amanda Anisimova.

Schmiedlova opened their title defence with a 6-2 6-4 victory over Ysaline Bonaventure in the Colombian city of Bogota on Monday.

The fourth-seeded Slovakian player will next meet Brazilian qualifier Beatriz Haddad Maia at the WTA international clay-court event.

Haddad Maia won the last five games of the second set in her 6-2 7-5 triumph against German Laura Siegemund.

American Anisimova advanced from the first round after rallying past former Wimbledon finalist Lisicki 4-6 6-3 6-2.

Anisimova claimed her first win on clay in almost two years, with the 17-year-old having missed the 2018 clay-court swing due to an ankle injury and lost to Petra Martic in the Charleston Open last week.

Varvara Lepchenko accounted for Elitsa Kostova 6-3 6-1, wildcard Maria Camila Osorio Serrano beat Conny Perrin 6-4 6-4 and Jasmine Paolini outlasted Francesca Di Lorenzo 6-2 3-6 6-4.
