It was only the second horse Stewart had raced at the Warragul Pacing Bowl during 2018, but Tiger Storm's victory goes down in the record books with the success bringing up 300 victories for the season for the stable, passing the previous mark of 299 wins set by Queensland horseman Bill Dixon in 2010/2011.
Tiger Storm ran a a short-priced favourite on Sunday, and went straight to the front at the start of the race for driver Chris Alford, one of four wins on the day for the master horseman who himself has set a national record for winners driven this season.
Alford's quartet of victories enabled him to secure the Warragul Driver of the Year title for the fifteenth time.
Three of those victories came for Gippsland horseman Gary Quinlan, who was once again crowned Trainer of the Year at Warragul.
His winners on Sunday were Scruffy Marshall, Starofsahara and Emiliana.
Feature race on Sunday was the Women in Trotting Tribute, to acknowledge the involvement of females past and present in harness racing.
The race, for female drivers only, attracted seven starters, and, fittingly, local reinswoman Casey Parker drove the winner, Rocknroll Gold.
It was Parker's biggest racetrack success so far, having been a past graduate of the Gippsland Harness Training Centre.

Fellow local Simone Walker drove Montenero to produce a local Quinella.
The winner is trained by Michael Hughes, who produced a double on the day, after Express Yourself won the Trotters Handicap.
Hughes has recently settled into a new property at Iona, and Sunday's victory by Express Yourself was the first winner from the new facility.
Gippsland trainer Steve Austen was a proud man after his horse Priddy Easy won the first race of the day.
Four months ago Priddy Easy suffered a nasty chest injury after a paddock accident at Austen's Labertouche property.
He and his wife Karen have nursed the horse back to health, and Sunday's victory was the third for the pacer, which has also run nine minor placings.
Greg Sugars drove Priddy Easy on Sunday – his wife Jess trained Fong Nien to win the sixth event to bring up a double for the top reinsman.
