On Sunday at Fukuoka, Japan, Pakistan’s Mohammad Amaan Siddiqui set a new national record in the men’s 400-meter freestyle with a time of 4:12.29.
In the process, Amaan, 16, smashed the previous national record of 4:15.78, which he also set.
Despite setting a new national record, the 16-year-old Pakistani missed qualifying for the final, finishing 50th out of 55 swimmers, just 28 seconds behind the last qualifier.
The top eight swimmers from each heat advanced to the final.
Australia’s Samuel Short won the 400m race in 3:40.68, while Tunisia’s Ahmed Hafnaqui finished second in 3:40.70, just a microsecond slower than the Aussie.
Germany’s Lukas Martens, Brazil’s Guilherme Costa, Korea’s Woomin Kim, Switzerland’s Antonio Djakovic, Australia’s Elijah Winnington, and Austria’s Felix Auboeck round out the top eight.
