Slovenian qualifier Grega Zemlja pulled off the biggest victory of his career to date, defeating Janko Tipsarevic from a set down to make the Vienna final 3-6 7-6 (5) 6-2. After a wasteful first set that saw eight break points squandered from Zemlja, Tipsarevic would need just one to take the set. Zemlja opened up a 0-40 lead as Tipsarevic served for the set but all three were saved as the Serbian held to take the first set 6-3.
An early break in the second for Tipsarevic and it looked all but over, especially when he would gain two more break points on the next service game. Somehow Zemlja held and after going 3-1 down would reel off three straight games to take the lead in the set for the first time. After the break, no more break chances were held by either player so it was down to a tie break to decide the second set. Zemlja struck first in the topsy turvy tie break, earning the mini break and going 2-0 up before Tipsarevic won four straight points. Zemlja then won four straight points of his own to bring up two set points, the second of which was taken for a 7-5 tie break win.
An early break for 2-1 in the decider would be enough for Zemlja but he definitely made hard work of it. At 3-2, he found himself in a 0-40 hole but recovered and would then go on to punish Tipsarevic for failing to convert by getting the important insurance break. It looked like it would have been needed when more break points came Tipsarevic’s way but Zemlja held his nerve and finally held to confirm his place in the first ATP final of his career at the age of 26.
Juan Martin Del Potro needed two tie breaks to see of Luxembourg’s Gilles Muller in a 7-6 (4) 7-6 (5) victory. The match saw no breaks of serve and 33 aces (Del Potro 17-16 Muller) in a match where serve was dominant. Both players had one break point opportunity in the first which neither could convert. The first set tie break saw a surprising 5 of 11 points lost by the server as Del Potro came from 4-2 down to win the last five points and go a set up.
Del Potro faced 0 break points in the second set and would take early control in the second set tie break. However, a 5-1 lead soon was pegged back with three match points coming and going. A big serve on the fourth match point of the tie break would be enough for Del Potro to book his place in the final.
