SINGAPORE - Singapore's first and only Olympic gold medallist Joseph Schooling completed his final Big 12 Swimming and Diving Championships on a high by winning his fifth gold of the four-day competition on Sunday (Feb 25, Singapore time) at the Lee and Joe Jamail Texas Swimming Centre in Austin.

The 22-year-old won the 200-yard butterfly final in 1min 42.23sec, touching the wall ahead of West Virginia University's David Dixon (1:42.50) and fellow University of Texas swimmer Sam Pomajevich(1:44.38).

Earlier in the meet, Schooling had helped the Texas Longhorns take gold in the 200-yard medley and freestyle relays, as well as the 400-yard medley relay.

He also won the 100-yard fly final to complete the fly double, which he is hoping to repeat in his final NCAA championship, which takes place from March 21-24.

The butterfly specialist won both the 100- and 200-yard fly titles at the NCAA meet in 2015 and 2016, but failed to win either race last year. He had admitted to a lack of motivation after his triumph at the 2016 Rio Olympics but has vowed to rebound this year.
