Slovenian’s Grega Zemlja pulled off the biggest shock of the day at the Erste Bank Open 2012 in Vienna, defeating Tommy Haas in three sets 6-4 4-6 6-2. With the level of tennis he has been showing in the second half of the year, it seemed like Haas was a certainty for the 501st victory of his career. However it was not to be, with the qualifier Zemlja putting on a great performance.
After the pair traded breaks to begin the match, little else would come on serve except in the all important seventh game of the set. Zemlja would hold twice with easy to take a set lead, looking the like a shock was on the cards. The momentum soon swung the other way with Haas going up 4-0 in the second set, only to lose four straight games himself. Fortunately for the German, he would recover and break Zemlja for the third time in the set to force a decider.
Zemlja recovered from the disappointment of being broken to lose the set quickly and would lose just one point on serve in the final set, breaking Haas twice for the victory. Haas will be disappointed to have served poorly, especially on the second where he won just five of the thirty second serve points available.
Meanwhile, Juan Martin Del Potro had a much easier time in his match than the last round, with a comfortable straight sets victory over Marinko Matosevic. It wasn’t quite the thirty aces like the last round but Del Potro’s 6-2 6-2 victory was backed by a strong serving performance that saw him lose just three points on first serve. Two breaks in each set was enough for Del Potro to see off his Australian opponent in just 73 minutes.
