Wawrinka's Australian Open title defense ends in semifinals MELBOURNE, Australia (AP) — For the man nicknamed "Stanimal," this was not the way for defending champion Stan Wawrinka to go out of the Australian Open — with a whimper, not a roar. The Swiss player couldn't offer any resistance in the critical fifth set on Friday, falling 7-6 (1), 3-6, 6-4, 4-6, 6-0. Coming into the semifinal against Djokovic, he was starting to resemble the player who stunned the Serb last year in the quarterfinals — his first win over Djokovic in the last 15 matches — and then went on to beat No.
