Shannon Potter of Taylor Made Sales Agency, agent, signed the ticket for the colt on behalf of Louise and Kiki Coutelis' Paris, Ky.- based Town & Country Farms.
"He has plenty of upside, especially being a son of Speightstown," Potter said. "We're looking forward to running him and he will be shipped to (trainer) Todd Pletcher tomorrow."
Consigned by Baccari Bloodstock, agent, as Hip No. 380, the strapping 3-year-old chestnut is the first foal out of the Deputy Minister mare Fifth Avenue Ball.
Eastwood posted eye-catching victories in both of his starts this year. In his career debut he won a six-furlong contest at Belmont Park by 2 1/4 lengths May 27, followed by a gutsy head score in an allowance race at the same distance at the New York track June 29.
An earner of $85,200, Eastwood was formerly trained by Michael Mareina for Chris Baccari.
"I had a pretty good clue he would go for that much ($800,000) because it is hard to buy a 3-year-old colt that is sound," Potter said. "We are excited to make him a good racehorse and for him to be a potential sire."
"The (horses of racing age) sale has been great timing," he added. "The 3-year-old prep is over and Breeders' Cup is on the way."
Eastwood was originally a $240,000 purchase at the Keeneland November breeding stock sale when Baccari bought him from Taylor Made Sales Agency, agent. He was bred in Kentucky by Fred W. Hertrich III.
