"Ljubo" played very well. Ljubo is defending champion in Vienna, and he is now one step closer to defend the title, he is in SF. Wawrinka didn't have any answer for Ivan's game. Ljubo was fantastic today, and he is going to win this title for the 2nd consecutive year. Ljubo didn't face any break point on his serve in the match, and he took Wawrinka's serve three times. Once in the first set, and 2 times in second. He hit 11 aces!
