Mo,
Birdstone did. He ran in the Lanes End, though very poorly, waited five weeks then ran in the Derby, was ok, then ran a big one in the Belmont beating Smarty Jones. However his pair is a little misleading because his next race was the Travers, three months after the Belmont, so he went in on good rest.
The other two Lion Heart and Egg Head, are also unique. Lion Heart paired with an excellant effort in the Derby, regressed in the Preakness, won a suspect Haskel and pulled up lame in the Travers. Career over.
Egg Head was much worse, he followed his pair with a game second to Lost in the Fog in the Riva Ridge and about a month experienced the ultimate bounce.
He dropped dead.
