WHAT CONNECTIONS ARE SAYING
"We'd been impressed to see the change in the horse leading into the George Ryder and after racing so well against Winx he seems to have come out of it with more energy" - Kementari's trainer James Cummings
"These quirky types ... you've got to try and trick them into winning without putting too much pressure on them too early in the race" - Tom Melbourne's jockey Kerrin McEvoy
"He'll be there for a long way. Gai is the queen of winning the Doncaster. She is going for her eighth Doncaster win on Saturday, so she certainly knows how to win one" - Michael Dee, Arbeitsam's jockey
