Seasoned breaststroke swimmer Glenn Snyders produced a top class swim on the third morning of the world championships in Kazan, Russia, and had a part in the third world record of the event.
To cap an encouraging morning, Bay of Plenty's Nathan Capp set a national record in the 800m freestyle heats.
American-based Snyders was third in his heat of the 50m breaststroke in a season-best time of 27.23 seconds, eclipsing his previous mark by .27s.
However the star turn came from South African Cameron van den Burgh, who touched in 26.62s, shaving .05s of his own previous world record, set in Rome six years ago.
Snyder was seventh fastest into the semifinals to be raced early tomorrow.
Van den Burgh's mark was challenged hard by Britain's classy Adam Peaty, who put out a 26.68s, suggesting a cracking event is under way.
