Michael Phelps put the United States ahead to stay on the butterfly leg of the 4×100 medley relay, his last race before retiring, and Nathan Adrian finished it off, giving Phelps, the most decorated athlete in Olympic history, his 23rd career gold medal.
“Walking down the warm-up pool deck, I started getting choked up thinking this is my last ‘this,’ this is my last ‘that,'” Phelps said. “It was definitely more emotion than in 2012, and I think that’s a good thing.”
“This was the cherry on top that I wanted,” Phelps said after the race. “I couldn’t be any happier with the end of my career.”
