Trainer Paul McGee said Bet On Sunshine continues to train well."I don't see how he could have gone any better," McGee said.In his last start May 15, Bet On Sunshine finished fourth in a 6 1/2-furlong allowance race at Churchill Downs. McGee blames himself for that effort; he said he trained Bet On Sushine too hard in the weeks leading up to the race.Bet On Sunshine has won 22 of 44 career starts.
