WHO’S HOT Bodemeister rocketed to the top of the charts following his overpowering victory in the Arkansas Derby at Oaklawn Park. He was so impressive that Mike Watchmaker, Daily Racing Form’s national handicapper, has made him the 9-2 favorite on his future line for the May 5 Kentucky Derby. Dullahan, who rallied strongly to win the Blue Grass Stakes at Keeneland, is down to 10-1 this week after being 30-1 a week ago. WHO’S NOT Wrote was removed from consideration for the Derby, so he is the lone defection from last week’s top 20 list. Hansen, the co-third choice at 6-1 on Watchmaker’s line last week, is now the co-fifth choice at 10-1 after finishing second in the Blue Grass. Union Rags, Creative Cause, Gemologist, I’ll Have Another, and Alpha all had their odds raised just a tick to account for the price on Bodemeister. ON THE BUBBLE Castaway has a chance to vault into the top 20 for earnings in graded stakes races if he can capture the Lexington Stakes on Saturday at Keeneland. Trinniberg is not on the Derby Watch list, because his connections are leaning against the race, but he has enough money to run should they reconsider. If Castaway does not win, and Trinniberg stays out, then Reveron, the Florida Derby runner-up, would be one defection away from making the field.
