Karnataka swimmer Aaron Agnel D'Souza on Sunday bettered his personal national record in the 100m freestyle event in the 65th Senior National Aquatics Championships which drew to a close in Ranchi on Sunday.
D'Souza proved he was a better bet than statemate Rehan Poncha to qualify for the 2012 London Olympics when he clocked 51:15 sec to claim gold in the men's 100m free style event. The earlier mark was 51:43.
D'Souza bagged seven gold, helping Karnataka finish at the top with 23 yellow metals.
Karnataka's men fiercely fought even among themselves with D'Souza shattering Poncha's hopes of getting a sixth gold and pushing him to the second place in men's 200m butterfly stroke with a timing of 02:02:22 as against Poncha's 02:04:38.
"I am happy with my performance here as I collected gold and a silver. Now my eyes are set on qualifying for the London Olympics," D'Souza said.
"I was equal with Aaron in the first three laps, before falling behind. That is where fitness matters. But I know it is there in me and I will come back after a brief break," Poncha, who took five gold medals in the competition, said after settling for silver.
Olympic qualifier Sandeep Sejwal of RSPB improved upon his own national record in his men's 100m breast stroke event rewriting it with a timing of 01:01:97.
"It's the best timing without suit There will be no rest for me, I will continue training till the London Olympics," Sejwal, who bagged four gold medals in the competition, said.
