The United States' Tennys Sandgren on Thursday defeated ninth seed Stan Wawrinka 6-2, 6-1, 6-4 to qualify for the third round of the Australian Open tennis tournament.
Sandgren needed an hour and 28 minutes to eliminate eighth-ranked Wawrinka from his first tournament in 2018, reports Efe.
Wawrinka was suffering from a serious knee injury that had put him out of action for six months.
The 26-year-old American broke the 2014 Australian Open champion's serve five times out of 13 opportunities.
Sandgren is due to next face Germany's Maximilian Marterer, who beat Spain's Fernando Verdasco 6-4, 4-6, 7-6 (7-5), 3-6, 6-3 in three hours and 27 minutes.
