The legend of Australian racing pulled off a masterstroke with three-year-old So You Think who won the weight-for-age championship at just his fifth start.

''We did it again,'' Cummings said as he claimed his third Group1 race on consecutive Saturdays, this time with the least experienced horse.

''You can't buy experience and I've got a bit of that.''

So You Think ($14) did it the hard way, leading from start to finish with Glen Boss rating him perfectly with the other three-year-old in the race, Manhattan Rain stalking him all the way.

Just when it seemed their experienced rivals were poised to strike, the two youngsters kicked away with So You Think doing much the better, striding to a 212 length win.

Veteran Zipping did best of the rest finishing a long neck third with raging favourite Whobegotyou ($2.80) sixth.
