Lucky loser Viktoria Kuzmova scored her third win of the season with a rock solid 6-4 6-2 performance over the 4th seed Sorana Cirstea in an hour and 13 minutes. 19-year-old defended her second serve better and she outplayed Cirstea from the baseline with her strong groundstrokes, especially with her forehand.
Kuzmova saved all four break points she faced and she created no less than 14 break points, stealing Cirstea's serve three times to score a commanding win. The first set was close, with three break points for each and it was Viktoria who scored the only break in game three, keeping the lead throughout the set for a 6-4.
She saved two break points in game eight and the set was in her hands with a hold at 15 in game 10. Sorana fell apart in set number two after wasting a break point in game two, having to play against no less than 11 break points and dropping serve in the third and fifth games to find herself 4-1 down.
She fends off three match points in game seven but Kuzmova sealed the deal with a hold at love in game eight to advance into the second round. The 8th seed Donna Vekic needed just 64 minutes to pass the home teenager Panna Udvardy 6-3 6-3 for her fourth triumph in 2018. Vekic served at 69% and she faced only one break point to drop serve in the closing stages of the opening set.
That wasn't enough for world number 366 to make an impact, facing seven break points and suffering four breaks to stay on just six games. Donna did everything right in the first six games, controlling the pace and scoring breaks in games one and five to create a significant lead.
Serving for the set in game sight, the Croat lost serve at 15 but she recovered quickly to close the set with another break a few games later. Vekic sailed through her service games in set number two and Udvardy couldn't keep that pace, getting broken in game eight to hit the exit door when Donna held in game nine.
The Belgian qualifier Ysaline Bonaventure destroyed Sara Sorribes Tormo 6-0 6-0 in just 53 minutes, dominating from start to finish to earn her second WTA win in 2018. Four years ago the Spaniard celebrated 6-2 6-0 in their only previous duel and Ysaline got her revenge with interest, losing just 10 points in six service games and winning 67% of the return points to grab all the games of the match and move to the second round in the best possible way.
