Pliskova had argued heatedly with umpire Marta Mrozinska after her smash was called out when serving at 30-30 and 5-5 in the final set, and her Greek opponent won the game before serving out the match.
World No. 1 Simona Halep of Romania kicked off her campaign for a first Internazionali BNL d'Italia title with a comprehensive 6-1, 6-0 victory over BNP Paribas Open champion Naomi Osaka of Japan in the second round in Rome on Wednesday.
Simona needed a few games to set her range, saving four break points in game two and winning all 12 games up from that moment!
"She knew it and we were having a lot of backhand rallies, other than that I couldn't say what happened."I feel like I've played her the most of any player, this was the third time this year. I'm more relaxed than in Madrid", said Halep".
"It's tough to make winners on this court, for me, but it's good when I can build the point".
Today it was all about Halep, who saved all six break points she faced and took charge on the return as well, winning nearly 70% of the points in Osaka's games to notch six breaks from seven opportunities, dominating from start to finish and reaching the third round in style.
Osaka, 20, failed to convert any of her six break point opportunities, hitting 29 unforced errors to Halep's 14.The 26-year-old Halep reached the final in Rome last year and needs to reach the quarter-finals this time to hold her world No 1 ranking.
A decade after they last met in Rome, Maria Sharapova once again did enough to secure a victory over Dominika Cibulkova in three sets. Later in the day, the 13th seed battled past Donna Vekic 7-6 (2), 7-6 (0) in a tense affair.
