Top seed Maria bags comfortable win in Bogota
Tatjana Maria had few problems in her opening match at the WTA Bogota Open, defeating Georgina Garcia Perez in straight sets.
The top-seeded German triumphed 6-3 6-2 in just an hour and 15 minutes and will next face Chilean qualifier Daniela Seguel, who knocked out Nicole Gibbs 6-2 6-2.
Johanna Larsson, the tournament's third seed, came out on top in a tie-break in the first set against Ysaline Bonaventure before breezing through the second, the Swede progressing courtesy of a 7-6 (7-4) 6-1 win.
Anna Karolina Schmiedlova overcame 2016 champion Irina Falconi in a see-saw encounter, recovering from a woeful second set to win 7-5 0-6 6-1.
