WinStar Farm’s Rule will not compete in the Kentucky Derby, trainer Todd Pletcher revealed Monday morning. Winner of the Sam F. Davis (G3) and Delta Jackpot (G3), the dark bay colt was exiting a third as the favorite in the Florida Derby (G1).

His defection guarantees a spot for Jackson Bend in the Derby field.

Pletcher also announced that the filly Devil May Care will be entered only for the Derby. Her connections had considered cross-entering to both the Derby & Oaks, but she is now definite for Saturday’s 1 ¼-mile test against males.

On Monday morning at Churchill Downs, two-year-old champion and likely Kentucky Derby favorite Lookin at Lucky breezed five furlongs in 1:00 4/5 over the muddy track. Working in company, the Bob Baffert-trained colt recorded splits in :12, :24 1/5, :36 and :48 1/5, galloping out six furlongs in 1:15 1/5.

Illinois Derby hero American Lion received his first workout at Churchill, tuning up for Derby 136 with a five-furlong breeze in 1:02 3/5. Clockers recorded his splits in :12 3/5, :25 2/5 and :37 3/5, with a six-furlong gallop out in 1:16 2/5.

Interactif worked a half-mile in :47 3/5 with company. Pletcher, who labeled the colt doubtful recently but said a final decision wouldn’t be made until he worked, said afterward that Interactif’s status is still pending. The multiple Grade 3 winner recorded an opening quarter-mile split in :23 4/5 and galloped out five panels in 1:01 4/5.

Arkansas Derby upsetter Line of David, who received a tap of the whip down the stretch of his five-furlong move, worked in 1:01. His fractions were :11 4/5, :23 3/5, :35 3/5 and :48 1/5, galloping out six furlongs in 1:15.

Grade 1 winner Noble’s Promise, who worked in company for trainer Kenny McPeek, breezed a half-mile in :48 1/5. His opening quarter-mile went in :24 3/5 and the bay colt galloped out five furlongs in 1:02 2/5.

Beautician completed preparations for Friday’s 136th running of the Oaks, breezing four furlongs in :49 1/5. Her splits were :12 1/5 and :24 3/5, and she galloped out five-eighths in 1:03.
