Calandagan went from last to first to win the Grand Prix de Saint-Cloud for the second year in a row.
Officially the highest-rated horse in the world last year, the Gleneagles gelding – who clearly disliked conditions when disappointing in the Coronation Cup at Epsom – was settled at the back, 12 lengths off the pace set by Lambourn as Mickael Barzalona was happy to bide his time.
Barzalona made his move on the Francis-Henri Graffard-trained five-year-old two and a half furlongs out and stylishly picked off the field down the outside to win by a cosy neck from Cualificar and stablemate Sunly.
