Better Than Banksy sends White out a winner.

Just about everything that could go wrong did, but in the end, it was the finish that everyone was hoping for, with veteran trainer Gary White bowing out of racing on a winning note in Hobart on Sunday.

White, who began his career in 1980 and trained a winner with his first starter, ended his illustrious career by winning with the last horse he put a saddle on.

But that's where the drama started. The saddle shifted forward when the gates opened, and apprentice jockey Jackson Radley was forced to race in-font on a horse that normally settles back.

White admitted he thought the dream had gone pear-shaped, but despite all the difficulties, Better Than Banksy ($4) survived to win in a photo finish.

"Honestly with all my friends here today supporting me and the way the day started off with some placings and some average runs, gee!

"The saddle went forward. He had to ride him upside down; I'm telling you, this kid (jockey Jackson Radley) will be one of the best riders in Tasmania," an emotional White said after the race.

In a career spanning five decades, White has won just about every major race in the state and plenty interstate, including the 2009 Magic Millions 3YO with Tempest Tost, but it would be hard to see any of those achievements topping a winner with his last starter to 'bookend' a marvellous career.

"How gifted have I been? We do nothing special but to be afforded the opportunity and success, and for this fairy tale beginning and end, how fortunate have I been?" White exclaimed.

White, 68, retires a Hall of Fame trainer with more than 1100 winners, including more than 20 at Group and Listed level. He plans to enjoy retirement with his wife, Belinda, including a road trip around Australia in the near future.
