Salsify was a dramatic winner of the CGA Foxhunter Chase Challenge Cup at Cheltenham after Oscar Delta unseated Jane Mangan when leading on the run-in.
Oscar Delta jinked to the left, hitting the rope where there was no permanent rail. The daughter of trainer Jimmy Mangan was unshipped, leaving Salsify to repeat last year's victory.
Creevytennant set the pace but continually jumped out to the right and he was still in front until the fourth-last where Oscar Delta took it up.
The 10-year-old pulled away from Salsify between the third- and second-last fences and jumped the last with a handy lead.
He looked set for victory until it turned into defeat and agony for connections.
Colman Sweeney was able to coast his mount, trained by his father Rodger, over the line 20 lengths ahead of Divine Intavention with Cottage Oak a neck away in third.
Salsify is the first back-to-back winner of the amateur riders' Gold cup since Double Silk in 193-94.
