DOHA, Qatar - Petra Kvitova's mastery over Elina Svitolina continued on Thursday in Doha, as the Czech No.16 seed won her seventh straight match against the Ukrainian World No.3 to book her spot in the Qatar Total Open quarterfinals, 6-4, 7-5. 

A late break in Svitolina's last service game of each set helped Kvitova move safely through to the quarterfinals in Doha for the third time in her career, though she has never advanced further than the last eight in Qatar.

In seven straight victories which has improved the head-to-head between the two to 7-1 in Kvitova's favor, the Czech has now won 12 straight sets.

"I knew I had a good record against her which probably helped me, because I knew I have a good game to beat her," Kvitova told WTA Insider after the match.

"I was probablyl lucky today. Each set was about one or two breaks...I think it was pretty close in each set. we played really good rallies, and when I broke her, it was two great rallies from my side and her as well."

Kvitova last dropped a set in the head-to-head in their third match, as she came from a set down to win in Dubai in 2015, but she has not lost to Svitolina since their first-ever meeting in Cincinnati in 2014.

Her attacking tennis once again won out over Svitolina's stellar defense, as Kvitova struck 34 winners to 23 unforced errors - doubling the Ukrainian's total in each column - over the course of the 89-minute encounter.

Since a first-round defeat to Andrea Petkovic at the Australian Open, Kvitova has now won 10 straight matches, which includes a title at the St. Petersburg Ladies' Trophy and a pair of singles ties against Switzerland in the Fed Cup.

One of those 10 victories came against her quarterfinal foe, Julia Goerges. Kvitova defeated the German in three sets indoors in the semifinals en route to winning in St. Petersburg.

"When my coach told me after the match that I was playing Julia, I was like, 'Again? Oh boy!,'" Kvitova said.

"Now, we're playing outdoors and I think the wind is there for sure. It'll be a night match so the balls won't be flying as much. I think we're pretty similar in game style, so it'll be interesting for sure."
