Stan Wawrinka became the latest big name to crash out of the Australian Open after he was beaten in straight sets by Tennys Sandgren.
The Swiss ace, who was crowned champion at Melbourne Park in 2014, was comprehensively beaten 6-2 6-1 6-4 by his American opponent in what was just his second game back following knee surgery.
Wawrinka had beaten Ricardas Berankis in the first round and despite his clash with Sandgren being a step too far, he was pleased to have performed as well as he did after his injury layoff, particularly as he had only decided to compete at the opening Grand Slam of the year on the eve of the tournament.
"I think the last 12 days was more than what I could have dreamed coming here," Wawrinka said. "I really came without thinking I will be able to play the first match. That's a big step for me."
Wawrinka was not the only big name to be dumped out of the tournament on Thursday, as seventh seed David Goffin was also defeated in round two, going down 1-6 7-6 (7-5) 6-1 7-6 (7-4) to 36-year-old Frenchman Julien Benneteau.
Goffin is the highest seed to have been knocked out in the men's tournament to date, although fifth seed Dominic Thiem was given a huge scare as he battled back from two sets down to beat American Denis Kudla 6-7 (6-8) 3-6 6-2 6-2 6-3.
