Thiago Pereira of Brazil and Stefan Nystrand of Sweden broke world records on Sunday at the Arena short-course swim World Cup.
Pereira, who won six gold medals at the Pan American Games earlier this year, swam the men's 200m medley in 1 minute, 53.14 seconds, beating the time of 1:53.31 set by Ryan Lochte of the US last year.
Nystrand swam the men's 50 freestyle in 20.93 -- .05 faster than Roland Schoeman's mark set last year -- for his second world record and the fourth overall at the Europa-Sportpark pool in two days.
In five previous World Cups this season, just one record was broken.
Marleen Veldhuis of the Netherlands won the car awarded to the top performer after following a world record in the 50 freestyle on Saturday with a European best in the 100 Sunday. She timed 52.14, followed by Britta Steffen of Germany in 52.17 and Dara Torres of the US in 52.79.
On Saturday, Veldhuis beat Therese Alshammar and broke the Swede's world record by clocking 23.58.
