The top seed Elise Mertens is through to her fourth semi-final of the season following a convincing 6-3 6-1 win over the Italian veteran Sara Errani in an hour and 25 minutes, scoring her third triumph over the Italian in as many matches over the last two seasons. The Belgian lost 41% of the points in her games and she gave her serve away three times from five chances Errani created.
That didn't cost her much as the Italian struggled to find any rhythm behind her initial shot, serving at 76% but dropping almost 60% of the points to play against no less than 18 break points, getting broken seven times to end her run in the quarters.
It was the nightmare start of the match for both players, with seven break points in the opening eight games and Errani failed to hold to find herself 5-3 down. Mertens managed to save two break points in game nine before she held to take the set 6-3 and move closer to the finish line.
The Belgian kept everything under control in set number two and Sara was nowhere near that pace in her games, facing 10 break points and losing serve thrice to hand the win to her opponent. Su-Wei Hsieh has opened the season with the semi-final in Auckland and she will play in another one four months later after a one-sided 6-1 6-1 victory over an 18-year-old Katarina Zavatska in exactly an hour. This was the first WTA tournament for the junior since Seoul last September and she had nothing more left in the tank after scoring two wins in the previous rounds, winning just 38% of the points on her serve and facing 12 break points.
Hsieh broke her six times and she was rock solid in her games, dropping 12 points in seven service games to play against two break points, getting broken only once. Zavatska couldn't hold serve in the opening six games and Hsu-Wei raced into a 6-1 4-0 lead before she closed the match on serve in game seven, wasting a match point on the return in game six when Katarina managed to avoid a complete disaster and hold serve at least once.
