Lady Tak, the Fair Grounds Oaks winner who will probably be second choice in Friday's Kentucky Oaks, worked a half-mile in :49 under jockey Lonnie Meche at Churchill Downs Monday.
"She worked fantastic," trainer Steve Asmussen said of the daughter of Mukkadim who had her unbeaten streak of five races end with a second-place finish to Elloluv in the Ashland Stakes at Keeneland.
Also working Monday toward the Oaks were Columbine Stable's Go for Glamour, Island Fashion, and the Thoroughbred Corporation's Atlantic Ocean.
Trainer Beau Greely clocked Go for Glamour in :46 2/5 for a half-mile as the Pine Bluff filly galloped out five furlongs in :59 4/5. The Churchill clockers had her in :46 3/5 for the work.
"It was just what I wanted. She went beautifully," Greely said. "She handled the track well."
Atlantic Ocean breezed a half-mile in a quick :47 4/5 and galloped out five furlongs in 1:00 3/5.
"It was a very nice work," said trainer Bob Baffert, who is also pointing Santa Catarina toward the Oaks. "She wanted to do a lot and we just let her breeze. I think both fillies are ready to roll."
Second to probable Lady Tak in the Fair Grounds Oaks, Atlantic Ocean has also won two stakes. She will be ridden by David Flores.
With Sal Gonzalez Jr. aboard, Island Fashion worked a half-mile in :46 1/5, with trainer Nick Canani observing, "It's a little faster than we wanted, but she's ready to run. Sometimes it's hard to slow her down when she's ready to go. It's not going to hurt her."
Meanwhile, trainer David Vance said Carl Pollard's My Trusty Cat has not been eating well and won't make the Oaks starting lineup.
