Ashleigh Barty eased into the third round of the Qatar Open after dismissing qualifier Laura Siegemund in straight sets on Tuesday.

The Australian world No.1, appearing as the top seed at a WTA event for the 12th time in her career, racked up 19 winners as she dispatched her German opponent 6-3 6-2 on her first ever appearance at the Doha tournament.

Ranked 68, Siegmund, who owns three wins over top-five players, had come through qualifying before beating Yaroslava Shvedova in round one, but was unable to live with Barty’s greater consistency and serving potency as she suffered defeat in one hour and 13 minutes.

“It took some time to adjust just to the conditions and having not played my opponent before,” Barty told WTA.com afterwards.

“Happy overall to be able to switch on when I really needed to. Disappointing to have a few lapses in concentration but also a credit to my opponent, she came up with some really good stuff in runs to be able to break me a few times.”

Up next for Barty will be a rematch of her Australian Open third-round clash with Elena Rybakina after the 14th seed battled past Belgian Alison Van Uytvanck 5-7 6-2 7-6 (10-8).
