At Royal Randwick on day one of The Championships, Darley's unbeaten European Champion juvenile & dual Gr1-winning shuttler Teofilo (Galileo-Speirbhean, by Danehill) celebrated an elite race success when 7YO Australian-bred gelding Happy Clapper (Teofilo-Busking, by Encosta de Lago) showed his superiority when scoring a comfortable 2 length win in Australia's premier mile handicap, the $3 million Gr1 Doncaster Mile (1600m) for 3YO+, defeating Comin' Through & Arbeitsam. This was the third top-flight success for Happy Clapper who advanced his record to 11 wins (including the Gr1 Canterbury Stakes, Gr1 Epsom Handicap, Gr2 Tramway Stakes, Gr2 ATC Villiers Stakes) & Gr3 Newmarket Handicap) and 12 placings (including the Gr1 George Ryder Stakes, Gr1 VRC Emirates Stakes, Gr1 George Main Stakes, Gr1 ATC Doncaster Handicap – twice & Gr1 ATC Queen Elizabeth Stakes) from 34 starts for $5,945,050 in earnings. Winning trainer Pat Webster said the Doncaster was the one race he always wanted to win when he was growing up. "You can have your Golden Slippers and you can have your Cox Plates but when we were kids The Doncaster was always the race we wanted to win. I watched my first Doncaster from the Leger when Tobin Bronze won in 1967," Webster told Sky Racing. "I grew up here and this is the race I've always wanted to win. It's a dream." Jockey Blake Shinn commented: "That is amazing. I have just won a Doncaster," he said. "To win a Doncaster and put my name in the history books with this horse who deserves it is very special." Happy Clapper became just the tenth horse in history to claim the Epsom & Doncaster double, joining the likes of Winx, Super Impose and Gunsynd. Happy Clapper also earned himself an automatic entry in the Gr1 Breeders' Cup Mile at the Breeders' Cup World Championships at Kentucky on November 2-3.
