Karolina Pliskova, the top seed here at the Aegon Open in Nottingham, brushed aside the challenge of Anna Tatishvili.
The Czech needed less than an hour to romp past Tatishvili 6-1 6-3 and avenge her shock exit in the opening round at last year’s US Open.
The world #17 breezed into the quarter-final stage, dropping just one game to wrap up the first set in 21 minutes – but needed a second set point to take the lead.
Pliskova’s sheer athleticism was the difference between the players, but she stuttered at times in the second set as the low bounce and speed of the drives from the American caught her out.
She edged ahead 4-3 to regain momentum and then overwhelmed her opponent to claim victory.
The former top 10 player explained: “I just came from clay, so every match is important,
“It’s better than just practicing, my serves and returns were better today. She was frustrated by my serve in the first set and half of the second set.
“But I didn’t hit that many aces in the second set, and that was probably the biggest difference between the two sets.
“But I got nearly every first serve in in the first set, and that’s so important on a fast surface like the grass here in Nottingham.”
