ST. PETERSBURG, Russia - In a matchup between two Grand Slam champions, it was Petra Kvitova who put on a masterclass to defeat No.2 seed Jelena Ostapenko and reach the semifinals of the St. Petersburg Ladies' Trophy on Friday, 6-0, 6-2.
The two-time Wimbledon champion was near her vintage best over the couse of the 58-minute affair, breaking serve five times to cruise to the most one-sided victory in the pair's five head-to-head meetings.
A bagel first set for the Czech saw her strike eight winners in six games, as she routinely pinned Ostapenko at the back of the court with a barrage of powerful grounstrokes.
In the second set, Ostapenko stayed on serve over the first five games, but two double faults in a costly sixth game of the set helped Kvitova claim the decisive break for the match.
Kvitova did not face a break point in the second set, but dug out of a 0-30 hole in a mammoth seventh game which went to deuce three times as Ostapenko looked to draw level, and capped the match with a backhand return winner to advance to her first semifinal of the season.
"At the end of the last match, I found my rhythm a little bit - I knew I had to play a little bit better today, against someone who is playing very aggressive. I had to stay focused on every point, which I did today," Kvitova said on-court after the match.
"It was just about a few games which I was serving and kept my serve...I served pretty well today, so it was great."
Kvitova served four aces in the match, losing just three points on serve for 89% of points won behind her first delivery.
The Czech struck 13 winners to 10 unforced errors, while Ostapenko managed just eight winners to go along with 16 unforced errors in the match.
Making her in St. Petersburg, Kvitova scored her 62nd career victory on indoor hard courts, the most among active WTA players.
In addition, she is the second wildcard to reach the semifinals in the brief history of the event, joining 2017 semifinalist Natalia Vikhlyantseva.
With the victory, Kvitova will square off in the semifinals against the streaking Julia Goerges, as the No.5 seed ended the run of teenage qualifier Elena Rybakina with a 6-3, 6-3 victory. The 2017 champion at the Kremlin Cup in Moscow, Goerges has won her last eight matches on Russian soil.
