Philson Run shrugged off his lack of experience to grind out a famous victory in the John Smith's Midlands Grand National at Uttoxeter on Saturday.
Paul Carberry took the ride - his only mount of the day at the Staffordshire track - on Nick Williams' nineyearold but only just, having weighed out with only a minute and a half to spare.
He was always going well on the 14-1 chance in the £100,000 feature over a stamina-sapping four miles and a furlong.
After giving Philson Run a patient ride in the early stages, he took closer order going down the back straight for the final time before joining the leaders leaving the last bend.
D'Argent, the 5-1 favourite, was travelling strongly in the lead when he blundered and unseated Robert Thornton at the third last.
Philson Run was left in front and he had to be kept up to his work to hold off the persistent Toulouse-Lautrec (7-1) by a length with Howdydoody (8-1) another seven back in third. L'Aventure (12-1) was fourth.
The jockey's late arrival had been a cause of concern for Williams, who said: "He [Carberry] made it by a minute and a half. Mattie Batchelor was on standby. Ruby Walsh said he'd spoken to Paul and he said he was on his way.
"I was not confident he'd get here - more hopeful. Dave Dennis would have
ridden him but he couldn't do the weight."
It was quite an achievement by Williams to get Philson Run to the track, for what was only his fourth start under Rules, as the gelding has "terrible legs".
The trainer is hoping that if his charge stays sound he could develop into a 2006 Grand National contender.
"We had him as well as we possibly could given his legs are a bit fragile and when we were being caught on the runin I was a bit worried we hadn't done enough," Williams said. "When D'Argent went three out that obviously helped.
" He's in the Scottish National but it would have to be on the soft side. He wouldn't go if it was fast ground. If he keeps sound, we'll look at the Becher Chase and Grand National next season. He wasn't high enough in the weights to get in the National this year but he will be now."
Explaining his late arrival, Carberry calmly said: "There was no rush. I just had the one ride so I just came in time for it.
"I gave him a breather, which is always a big help in a four-mile race, and when I asked him to go he went but he was a bit starey in front. I could have done with more of a lead and if the other one hadn't come down three out he would have held us a bit longer. He's just the type of horse for the Grand National."
