Zverev Taken To Brink In Five-Set Australian Open Thriller
World number six Alexander Zverev was pushed to the limit at the Australian Open on Thursday, needing five gruelling sets to beat Slovak qualifier Lukas Klein. Facing a second consecutive second-round exit in Melbourne, the German came back to win 7-5, 3-6, 4-6, 7-6 (7/5), 7-6 (10/7) after a gripping contest lasting four-and-a-half hours on Margaret Court Arena. But it was major wake-up call for the sixth seed against a player ranked 163, in only his second Grand Slam and who currently has no coach.
