LINZ, Austria - Top seed and Wimbledon semifinalist Magdalena Rybarikova got off to a winning start at the Upper Austria Ladies Linz with a straight sets win over Richel Hogenkamp on Tuesday, 7-5, 6-3. 

Rybarikova saved 10 of the 12 break points she faced in the match and won the last four games, as the World No.28 broke the Dutchwoman's serve five times over the course of 91 minutes.

The top seed was joined in the second round on Tuesday by No.7 seed Tatjana Maria, as the German ousted Ons Jabeur, 6-1, 6-4 to start the day's play.

However, No.4 seed seed Anett Kontaveit was not as fortunate, falling at her first hurdle to Romanian qualifier Mihaela Buzarnescu, 7-6(8), 6-3.

The 29-year-old Romanian has been on a tear in 2017, winning a staggering five titles on the ITF Circuit, posting a mid-season 16-match winning streak, and improving her ranking by over 200 spots since the Australian Open in January.

However, a maiden WTA main draw victory had eluded her this season until she arrived in Linz, though she recently qualified for her first Grand Slam and fell to Caroline Wozniacki at the US Open.

After opening up a 4-1, double break lead on the No.4 seed in the opening set, Buzarnescu was forced to save a set point in the 10th game and one more in the tiebreak before finally taking a one-set lead in over an hour. 

Buzarnescu broke twice more in the second set to secure her first WTA main draw victory, and had the World No.35 her seventh defeat in eight matches since reaching the final of the Ladies Championship Gstaad in July.

In other first round action, qualifier Viktoriya Tomova and Ajla Tomljanovic each came from a set down to book their spots in the second round; the Bulgarian qualifier defeated lucky loser Naomi Broady, 3-6, 7-6(6), 6-4, while Tomljanovic saw off Monica Puig, 3-6, 6-4, 6-1. 

"I just hung in there. I know she can come up with great tennis," Tomljanovic said. "I've actually played her so many times in practice because we live in the same place, so I knew at any moment, it could switch."

The former World No.47 was twice a break down in the second set before rallying to knot the match at one set apiece, and never faced a break point in a dominant showing in the deciding set. 

"When I broke at 1-2 down [in the second set], I felt I was back in it. I knew that if I just kept my level up, it would be a good match."

Tuesday's final match saw No.3 seed Kiki Bertens fall in an upset against American Varvara Lepchenko, 6-3, 7-6(4).
