A horse broke down in the fourth race at Pimlico on Saturday, leading to the injury of several jockeys who had mounts in the major stakes races that followed.

On the backstretch in the optional claiming race for fillies and mares, Tom'sthreetees, a 3-year-old trained by James Lawrence, broke a front leg and went down. Jockey Ramon Dominguez managed to avoid the fallen horse with Gran Amiga, but Miss Trouble threw jockey Luis Garcia while jumping Tom'sthreetees, and both Abel Castellano Jr. and Eric Camacho fell attempting to get out of the way.

Garcia, 20, suffered a neck injury and a concussion, while Eric Rodriguez, 24, who rode Tom'sthreetees, fractured his left wrist. Tom'sthreetees was euthanized following the race.

Garcia had one more mount scheduled, on Hear Us Roar, the favorite in the $100,000 Selima Stakes for 2-year-old fillies. He pleaded with the track physician to allow him to ride but was denied. John Davison, whose sister, Rosalee Davison, owns Hear Us Roar, offered the mount to jockey Jerry Bailey, but the Hall of Fame rider turned him down to rest in the jockey's quarters.

Stewart Elliott, who later rode De Francis Dash winner Wildcat Heir, picked up the mount and Hear Us Roar stubbornly held off Take a Check to win the Selima by a head. She finished the 11/16-mile race in 1 minute 46.24 seconds.

"We were frantic for a rider," said Francis Campitelli, who trains Hear Us Roar.

* LAUREL FUTURITY: Defer, a beautifully bred colt based in New York, won the 81st running of the Grade III race, beating just four other runners by two lengths and completing the 11/16-mile race in 1:45.48. The historic race was run as the Pimlico Futurity from 1921 to 1965 and only once at the track -- in 1979 -- since then. With the Laurel racing surface under reconstruction, the race was moved to Pimlico.

* ANNE ARUNDEL STAKES: Essence, trained by Todd Pletcher in New York, led wire-to-wire, refusing to be passed in the stretch by Rare Gift, to win the 11/8-mile Grade III race for fillies and mares. Ridden by John Velazquez, the 3-year-old daughter of Gulch won her first stakes race, finishing in 1:49.37.

* CHARLES H. HADRY STAKES: Local runner Irish Colony rallied three wide in the stretch to upset a deep field at odds of 13-1. Trained by Ron Cartwright at the Bowie Training Center, Irish Colony beat millionaire Bowman's Band by 11/2 lengths to win the 11/16-mile race in 1:43.30. Bowman's Band, who competed in seven Grade I stakes races this year, will retire to the Maryland Stallion Station for the 2005 breeding season.
