Schooling makes life harder for Phelps after beating 'the master' in 100m butterfly heats
Singapore's Joseph Schooling made life harder for Michael Phelps after beating the master in their 100 meters butterfly heats on Thursday and going through to the semi-finals with the fastest time.
The Texas-based swimmer, a 100m butterfly bronze medalist at last year's world championships, set a time of 51.41 seconds with boyhood idol Phelps second in the heat with a 51.60 that left him fourth overall.
"It feels like a morning swim. Relaxed, easy," Schooling told reporters.
Phelps has already amassed three golds at the Rio Games and has other priorities, balancing the need to qualify comfortably without damaging his chances for the evening men's 200m individual medley final.
If the American wins that event, for his 22nd Olympic gold and 26th medal, he will become the first swimmer to win the same event at four successive Games and only the third athlete after discus thrower Al Oerter and long jumper Carl Lewis.
If that fails, the 100m butterfly gives him a second chance to pull off the feat as he has also won that at the last three Games and holds the world record of 49.82.
