SINGAPORE - Joseph Schooling capped a successful showing at the Big 12 Swimming and Diving Championships by breaking another record in the men's 400-yard freestyle relay on Saturday (Sunday, Singapore time) in Austin, Texas.

Swimming in the first leg of the final event of the four-day meet for the Texas Longhorns, the 21-year-old Singaporean clocked 42.24sec in his split to help his relay quartet set a new meet record of 2min 48.66sec, eclipsing the previous mark of 2:49.17 set in 2009.

While Schooling's time was not enough to break the 100-yard freestyle meet record of 41.92, his split was the second-fastest among his team-mates, Jack Conger (42.35), Brett Ringgold (41.80) and Townley Haas (42.27).

It was Schooling's third record-breaking swim at the four-day meet. The Olympic 100m butterfly champion also set a new 100-yard butterfly meet record on Friday and smashed the conference 50-yard freestyle record on Thursday.

Earlier in the day, Schooling pulled out of the 200-yard butterfly final after topping the prelims in the same morning.

"I think I had a good meet overall," said Schooling. "There were a couple of things that I tried in this meet in preparation for the NCAA (National Collegiate Athletic Association) swimming championships (next month).

"From here, I will sit down with (coach) Eddie (Reese) to discuss on how to approach the NCAAs. I do feel that it is working out really well for me, from the times I've clocked in this meet. So I am looking forward to see what I can achieve next month."

The Big 12 Conference comprises 10 schools from five states in the US and has a short-course yard (25-yard laps) format.
