WHO'S HOT Code West, Ive Struck a Nerve, and Orb are the three newcomers to this week’s Derby Watch Top 20. Orb, who won the Fountain of Youth last Saturday, is the co-fifth choice at 12-1 on the Kentucky Derby future line set by Mike Watchmaker, Daily Racing Form’s national handicapper. Ive Struck a Nerve, the upset winner of the Risen Star, is 40-1 on Watchmaker’s line, with Risen Star runner-up Code West 30-1. WHO'S NOT Violence was removed from the list after suffering a career-ending injury in the Fountain of Youth. He’s Had Enough was dropped after finishing a well-beaten fifth in the Fountain of Youth. Dynamic Sky also was bumped, though he did nothing wrong. He simply was the odd horse out to make room for the three newcomers. ON THE BUBBLE Treasury Bill continues to just miss the cut. Honorable Dillon and Tiz the Truth are also knocking on the door. The promising Titletown Five makes his first start of the year in the Gazebo Stakes on Saturday at Oaklawn. Of the 12 horses entered in the Gotham at Aqueduct on Saturday, just two – Overanalyze and Vyjack – are in the top 20, so a win by anyone else could vault them onto the list.
