Trainer Raymond Stifano, who was involved in last spring's mixup of two thoroughbreds at Maryland race tracks, has had his license revoked by the Pennsylvania Racing Commission, reportedly for unrelated reasons.

Stifano was apparently ruled off in Pennsylvania on the grounds of a 1968 conviction of having received stolen property. Stifano has duly reported that conviction on his license applications while racing.

Stifano had received a temporary license to race in Pennsylvania while his application was being checked.

Charles Trimmer of the Pennsylvania Racing Commission confirmed that Stifano's license had been revoked, but declined to discuss details.

The suspension effectively bars Stifano from racing at other North America tracks. On Tuesday, he was scheduled to saddle Get Off My Line in the second race at Laurel, but when state Steward J. Fred Colwell learned of Stifano's revoked license, he said the horse had to be scratched.

None of the horses Stifano trains will be permitted to race until they are turned over to another trainer, or until his license is reinstated.

Stifano, reached at his Delaware home, refused to elaborate on the situation, saying only, "You'll have to talk to my lawyer about it."

Stifano's lawyer, William Wilson of New Jersey, was unavailable for comment yesterday.

Last spring, Stifano came under scrutiny for racing Dr. Peatoppy under the name of a less talented animal, Sun Dandy, on three occasions. When the error was discovered, the matter was investigated by the Maryland Racing Commission and appeared to be resolved.

But two weeks ago, FBI agents began questioning race track workers about the mixup, and issued subpoenas to several horsemen, who have appeared before a federal grand jury in Baltimore.

Stifano is expected to appeal the suspension.
