TwinSpires' Ed DeRosa & PredictionMachine's Dan Zucker discuss the upcoming weekend after patting themselves on the back for correctly tabbing stakes winners Conquest Two Step and Lord Nelson last week at Santa Anita Park. This week the action has mostly a Kentucky Derby bent with the Withers at Aqueduct and Lewis at Santa Anita kicking off the $1-million Road to the Kentucky Derby SHOWdown at TwinSpires.com plus the Derby Future Wager. However, mentioning the San Antonio Stakes is a must, too, of course, as Horse of the Year California Chrome, champion Shared Belief, and Grade 1 winner Hoppertunity all show up.
