Milo Perrins will resign as announcer at Laurel and Pimlico race courses effective Nov. 30.

Perrins, who has called races at Maryland's thoroughbred tracks since July 1989, submitted his resignation yesterday to the Laurel office of Joe De Francis, president and chief executive officer of the tracks. De Francis, who was not at the track yesterday, spoke with Perrins late in the afternoon; Perrins called the conversation "amicable."

Perrins said he plans to return to New Mexico to call races at The Downs at Albuquerque and The Downs at Santa Fe beginning Jan. 11. Together, the two tracks operate about 10 months a year.

Perrins, 31, said the decision was made largely for personal reasons. He said he and his wife, Kathy, prefer the Southwest, where each previously had lived.

"We gave the East Coast a shot," Perrins said. "My wife's decided she wants to teach full time, and she'd rather do it in a more rural environment. Kathy's more accustomed to it out there, and I was born right outside of Yellowstone Park. It's mostly about lifestyle. That's where we came from; that's where we're going back to."

Perrins had called races at Hollywood Park in California, Prairie Meadows in Iowa and Blue Ribbon Downs in Oklahoma -- in addition to about a half-dozen other tracks -- before he came to Maryland 16 months ago. At the time, Laurel and Pimlico were without a full-time announcer following the resignation of Robin Burns; Trevor Denman was calling the races temporarily between sessions in California.

Burns, now the announcer at Rosecroft Raceway, said he would consider returning to the Maryland thoroughbred circuit. Rosecroft's future as a harness track has become less certain given the legal and financial entanglements of owner Mark Vogel.Prado Recuperating

Edgar Prado probably won't ride for another two weeks, agent Steve Rushing said. Prado, who had surgery Oct. 25 to repair a tear near a kidney, was scheduled for release today from Good Samaritan Hospital in Baltimore.
