A P McCoy has to work hard on comeback ride after injury His mount, Key To The West, may have finished 18 lengths behind runaway winner Ballyalton, but he gave the champion a thorough workout by pulling hard during the first part of the race and then having to be pushed hard in the latter stages. McCoy, who has two rides over hurdles at Huntingdon today, said: "It was a good one to start off with, pulling and pushing. I'm going to take it quietly for a week, with a few rides a day, then we'll kick on. Owner Graham Wylie had his biggest winner in Ireland since moving part of his string to Willie Mullins in the summer when On His Own, who was out in front for most of the last circuit, won the Goffs Thyestes Chase under David Casey. Afterwards Mullins said: "We thought he had a sneaky chance in the Paddy Power, but his missed the break that day and was still travelling quite well when he was brought down and I sort of forgot about him. He was the only fellow up there jumping all the way today. He's a big strong horse and the weight was nothing to him. We'll give him an entry in the Grand National now. David Pipe has decided to give Saturday's Argento Chase at Cheltenham a swerve with his unbeaten novice chaser Grands Crus. The trainer had been toying with the idea of pitting the grey seven year-old in against more seasoned chasers in this Gold Cup trial. However, Grands Crus is now pencilled in for what should be a less- arduous race, a three-mile novice chase at Newbury on Feb 11. "We've decided we don't want to give him a hard race with Cheltenham just around the corner in March," explained Pipe. Captain Chris, who finished third to Kauto Star in the King George on his latest run, is the new 11-4 favourite for the race with Coral.
