For progroupracing.com.au Daggy & Beave give all their thoughts on a massive day of Group 1 racing headlined by the ATC Sires for the 2 year olds, ATC Derby, The TJ Smith Stakes & The Doncaster Mile.Star filly Montefillia is tipped by both to beat the boys in the staying contest.A great supplementary card at Caufield and a few bets from The Beaver at Doomben & Morphetville to add some cream on top.
