ARCADIA, Calif. - There is absolutely no truth to the rumor that the entrance to the Santa Anita jockeys' room has been replaced with a revolving door. However, this exchange heard recently between racetrack wiseguys should hardly come as a surprise:
"You hear Desormeaux is going east again?"
"You mean he's going back to Japan?"
"No, the other East."
The peripatetic Mr. Desormeaux - he of the two Kentucky Derbies and Hall of Fame plaque - has become the poster child for a restless generation of stellar West Coast riders.
