WHO’S HOT By his own admission, trainer Todd Pletcher thought his 2-year-old males of last year were going to be slow to develop, and he’s had just one runner, Zulu, on Derby Watch since the top 20 first came out last month. That number just tripled. Destin, the Sam F. Davis Stakes winner, and Rally Cry, set to run Saturday in the Gotham Stakes at Aqueduct, both were added this week when two spots became available. Destin is 30-1 on the Kentucky Derby future line set by Mike Watchmaker, Daily Racing Form’s national handicapper. Rally Cry is 50-1. Zulu, second last week to Derby favorite Mohaymen in the Fountain of Youth, is down to 15-1 after being 20-1 a week ago, making him the co-sixth choice with Gun Runner and Mo Tom. :: DERBY WATCH: Top 20 list | Shagaf is Shadwell's Kentucky Derby homeboy WHO’S NOT Awesome Banner and Awesome Speed were not very awesome in the Fountain of Youth and were dropped from the list. :: ROAD TO THE KENTUCKY DERBY: Prep races, point standings, replays ON THE BUBBLE Fellowship, third in the Holy Bull and Fountain of Youth, continues to knock on the door. Adventist, third in the Withers last time out in only his second start, could move onto the list with a big showing in the Gotham.
