After his record-breaking swim on Thursday, Joseph Schooling broke one more record with yet another win at the ongoing Big 12 Swimming and Diving Championships in Austin, Texas.
The University of Texas (UT) student clocked 44.06 seconds to win the 100-yard butterfly on Friday, ahead of UT team-mates Jack Conger (44.56) and Brett Ringgold (46.32).
In doing so, he lowered the meet record of 44.62sec that he set last year. It is also just off his personal best and National Collegiate Athletic Association (NCAA) record of 44.01sec, which he also set last year.
The 21-year-old is tipped to eclipse that at the NCAA Championships next month, where he will also have Tom Shields' US Open record of 43.84sec in his sights.
Schooling is the reigning NCAA champion in the 100- and 200-yard fly.
The Singaporean's latest feat came after he smashed the Big 12 Conference 50-yard freestyle mark on Thursday.
Then, the Olympic 100m fly champion clocked 18.76sec to erase American Jimmy Feigen's Big 12 Conference record of 18.84sec, which had stood since 2009.
Schooling's next individual event at the meet is the 200-yard fly.
The Big 12 Conference comprises 10 schools from five states in the United States, while the NCAA Division I Swimming and Diving Championships, which will take place in Indiana next month, boast the top swim colleges in the US.
Both events have a short-course yard (25-yard laps) format.
