Michael Phelps is heading to his fifth Olympics.
The most decorated athlete in Olympic history held off a stiff challenge from Tom Shields to win the 200-meter butterfly at the U.S. swimming trials in 1 minute, 54.84 seconds.
After whipping around to look at his time -- which was likely a bit slower than Phelps would've preferred -- he held up all five fingers on his right hand to signify Olympics No. 5.
Shields came on strong to take the second spot on the Olympic team in 1:55.81.
Watching from the stands was Phelps' fiance and their 7-week-old son Boomer, who was wearing noise-canceling headphones adorned with American flags.
Phelps still has two more events at the trials: the 100 fly and 200 individual medley. He could swim as many as six events in Rio, counting relays, looking to build on his 18 golds and 22 medals overall.
