Delta Work has denied Tiger Roll a record-equalling sixth victory at the Cheltenham Festival by winning the Cross Country Chase.
Tiger Roll had been heavily backed to prevail in his last-ever appearance at Cheltenham, and it was confirmed after the race that this would be his final outing of a legendary career.
The 12-year-old ran a brilliant race, keeping his nose ahead of his stablemate, but the pair were neck-and-neck after jumping the last.
In the twilight of his career, the Davy Russell ridden horse did not have the engine to hold off Delta Work, who just about got over the line in first place.
After the race, Russell told ITV: "He always seems to get me out of jail but unfortunately it wasn't to be."
Trainer Michael O'Leary added: "He's won here five times, finished second. He ran well, he came home sound and we'll retire him now. This will be the last time they will see him race on a racetrack - he's a legend.
Plan Of Attack, a 25-1 shot, came home in third spot.
