Sadler's Joy (Tom Albertrani/Julien Leparoux) came with a scintillating late run to claim the Sword Dancer as the Aidan O'Brien-trained Idaho faded away in the closing stages to finish sixth of seven in the Grade 1 contest.
The Irish contender, a brother of renowned globetrotter Highland Reel, was sent off favourite and duelled at the head of affairs with Frank Conversation for much of the race, but the exertions took their toll down the home straight.
As the front two started to backtrack inside the final furlong, the pack closed up but nothing could live with the finishing kick of Sadler's Joy (7-1), who blasted home from the rear in the hands of Julien Leparoux.
After third-placed finishes in two Grade 1s – the Man o' War and Woodford Reserve Manhattan – earlier in the season, Sadler's Joy relished the return to 1m4f to secure a spot in the Breeders' Cup Turf with the race part of the 'win and you're in' series.
"He (Leparoux) has ridden him well every time," said winning trainer Tom Albertrani. "We had some misfortune, maybe, in the Man o' War when we got boxed in the whole race, but that's racing luck. Today he showed that kick. This horse has that tremendous kick and he did it today."
Twelve months after Arrogate announced himself on the highest stage in the Travers, Bob Baffert and Mike Smith were back in the winner's enclosure after West Coast produced a dominant wire-to-wire victory in the 148th running of Saratoga's signature race.
For the first time since 1982, the three winners of Triple Crown races came together but it was left to West Coast to confirm his potential stepping up in grade by registering his fourth straight success.
