Jockey Mary Wiley was taken to the Greater Laurel-Beltsville Medical Center yesterday with a fractured upper right arm after being involved in a spill at Laurel Race Course.

Riding See For Free in the fifth race, Wiley, 24, was vying for position in the run to the first turn when traffic from the outside closed the hole she was angling for. Her mount clipped the heels of another horse and she was thrown into the path of several oncoming horses, one of which appeared to strike her in the right shoulder.

Wiley was examined in the track's first aid room, then transferred to the hospital, where X-rays confirmed the fracture.

See For Free appeared unhurt.

Ohlaha, ridden by Kent Desormeaux, won the race. Wild Hunch, the outside horse who was held responsible for the crowding, was disqualified from third position by the stewards and placed last.

Later in the program, Sham Say, trained by veteran Bernie Bond, remained undefeated as she won the $43,100 What A Summer Stakes for 2-year-old fillies.

The gray daughter of Oh Say beat Gina's Double by six lengths for her fourth clear-cut victory. Ridden by Ben Feliciano, she ran the seven furlongs in 1:24 3/5 on a fast track. Sham Say will go next in the Maryland Juvenile Filly Championship on Dec. 5.

She paid $3.40 and topped a $9.40 exacta for those in the crowd of 10,367 who wagered on the 4-1 combination.
