Oaks/Derby Daily Double

we just had the feeling that she ran pretty hard in Arkansas,” said Fort of Mamma Kimbo’s 1 1/4-length victory in the April 11 Fantasy Stakes (gr. II) at Oaklawn Park. “When you start running horses three weeks apart, it catches up to them. She also doesn’t have a huge foundation; she only has two races.”

Prior to the Fantasy, the Bob Baffert-trained Mamma Kimbo broke her maiden by 5 1/4 lengths at Santa Anita Park Feb. 18. Bred in Kentucky by William Betz, Dr. Chuck Kidder, and Wayne Masterman, Mamma Kimbo is by Discreet Cat , out of the Devil’s Bag mare Bag Lady Jane.

so, she ran 2/18, and then 4/11. he mentions that racing catches up to them as a reason not to run, and then says she hasn't got much foundation.
that's a lot of trainer-speak there. it would be her third race of the year, but he's worried that over-racing would catch up to her?? lol yeah, that doesn't look as tho it'd be an issue.

sounds to me that she hasn't rebounded from a tough effort quickly enough. why not just say that??
