ClassicFamilies only shows horses that have won Classic races but of the Sportswriter-Rocknroll Hanover's listed - Lumineer's $258k is the biggest prize winner
I was surprised to see that Sportswriter has only ever produced one millionaire
It would have been worthwhile him covering a few homebreds this year as you would think that that is going to happen eventually
