PERTH, Jan. 3 -- Stan Wawrinka's 40-year-old legs didn't let him down over three-plus hours in his first singles match of a 2026 farewell tour on Saturday.
Three-time Grand Slam singles champion Wawrinka beat Arthur Rinderknech of France, who is ranked 29th to Wawrinka's 157th, 5-7, 7-6 (5), 7-6 (5). The match went 3 hours, 16 minutes.
Wawrinka announced in December that this year would be his last on the ATP tour.
Ahead of his first match, Wawrinka said he hoped to improve on his current ranking and move back into the top 100 before he retires. His highest ranking was No. 3, achieved when he won the Australian Open in 2014.
"I'm happy with the decision (to retire) and feeling at peace with that," Wawrinka said.
