“You never stop learning about horses,’’ Waller said.
“This horse, I’m Imposing, is an example because he’s a miler and we have only just worked that out.
“They change and keeping an open mind is the biggest key to a trainer’s success.
“If you close yourself in you become too one-dimensional.’’
Waller, the nation’s most dominant trainer, prepared a hat-trick of winners at Rosehill Gardens to take his tally of Sydney wins this season to 50, and celebrated the achievement with I’m Imposing’s Listed $100,000 Festival Stakes (1500m) triumph.
Once regarded as primarily as stayer, veteran I’m Imposing has been rejuvenated since Waller decided the gelding races best when kept fresh and racing mainly around 1600m.
I’m Imposing ($19), part-owned by TVN presenter Richie Callander, unleashed a powerful late surge to run down Estonian Princess ($21) by a short half head with another Waller-trained galloper, Strawberry Boy ($7) a long head away third, just in front of the luckless Generalife who was beaten a half length into fourth place after blowing the start.
Tye Angland, who timed I’m Imposing’s finishing run to perfection, admitted the old warhorse is not easy to ride.
“He’s an older horse and they tend to learn some tricks,’’ Angland said. “He can hang in a bit and to get the best out of him, you have to make him do it.
“But when he is on his game, like he was today, in a genuinely run race, if he gets a bit of luck, he will find the line.
“He travelled really good for me, we got out at just the right time, and everything worked out perfectly.
“At the 100m I thought he was going to get them and on the line I did think we had won.
“My main worry was that I haven’t had the best of luck in photo finishes of late so I was sweating on the result.’’
“She was unlucky,’’ Aspery said. “She didn’t get a lot of room in the straight.’’
