The New Zealand BMX riders Trent Jones and Matt Cameron have qualified through to the second day of the opening Supercross World Cup event of the year in Argentina.
Jones, ranked 20th in the world, won all three of his qualifying motos to advance to the elimination rounds.
He was the top qualifier, recording the fastest time of the day.
Cameron, third in his opening moto behind Jones and American Corban Sharrah, won his next two motos to qualify.
However Daniel Franks was unable to build on his opening round third with a fifth and a sixth to miss qualifying among the 156 riders chasing 48 places to the elimination rounds tomorrow.
"The conditions were excellent. This is a really good track in top condition and always produces excellent racing," said Cycling New Zealand BMX coach Ryan Hollows.
"Trent was impressive today and on his game. He was in control and recorded the fastest time as well."
"Matt was also very strong and impressed, while Dan was just a bit off. Today three third placings would have just got through, but in reality you need to be first or second in each moto to guarantee a spot."
Forty eight men join the 16 top ranked riders who were exempt through to the elimination rounds.
