Luca Cumani and Christope Lemaire rattled up a quick double at Sandown when the sprint victory of Ialysos was followed by Acrostic's triumph in the valuable Coral Challenge.
The 7-1 chance had finished fourth on both of his previous outings this summer and surpassed those efforts to deny Crackdown by a head, with favourite Mirrored third.
Cumani said: "We ran him at York over nine furlongs to see if he was a Magnet Cup horse, but he did not stay so we brought him back and this was a good alternative. It will be more of the big mile handicaps for him now."
Totesport trimmed the four-year-old into 7-1 from 12s for the totesport Mile at Glorious Goodwood.
