Stuart Crawford's rank outsider Yes Tom caused a major upset in the Daily Mirror Chase at Down Royal.
Having run well for a long way before eventually unseating Bryan Cooper on his return from injury in the Red Mills Chase at Gowran Park a month ago, Tony Martin's Grade One-winning chaser Bog Warrior looked to have a good opportunity to get back to winning ways in this three-mile-two-furlong conditions event.
The 6-4 favourite jumped and travelled with zest for much of the journey under Paul Carberry, but stopped quickly from the home turn and eventually finished a well-beaten fourth of five runners.
Yes Tom (14-1) , with over 20lb to find with the market leader on official ratings, was making his debut for County Antrim-based Crawford and galloped all the way to the line under Robbie Power to take the prize by seven lengths from Make A Track.
Raz De Maree was not far away in third, with the trio pulling clear of Bog Warrior and Ted Walsh's Grand National contender Seabass.
Crawford said: "I couldn't say I was expecting to win but I was expecting a good run.
"We are just trying to get his confidence back and in the last few weeks he's taken a bit more interest at home.
"He could have gone to Kelso, but this was on our doorstep and it was a small field.
"We'll aim for another race or two like that and then we might have a target with him."
