another serbian, novak djokovic, lost a five-set thriller to stanislas wawrinka, ending his 25 match winning streak at the event and 28 match winning streak overall. the defeat also ensured that there would be a new australian open finalist in the bottom half, as neither player from the opposing quarter-final (david ferrer and tomáš berdych) had reached the final before. berdych beat ferrer in four sets to reach his first australian open semi-final and became the latest player to have reached at least the semi-finals of all four majors.
