Maryland's best 2-year-old filly likely will step forward today as undefeated Sham Say takes on Thirty Eight Go Go and five others in the $100,000 Maryland Juvenile Filly Championship at Laurel.

The 1 1/16-mile race has the makings of a classic showdown. Sham Say, the 7-to-5 overnight favorite trained by Bernie Bond, has won each of her four starts by at least 2 1/2 lengths and has never trailed in the stretch. However, she is untested beyond seven furlongs and has raced exclusively in Maryland.

Not so with Thirty Eight Go Go (9 to 5). Bred and trained by King Leatherbury, the roan filly ventured to the Meadowlands in New Jersey two weeks ago and won the $200,000 Gardenia Stakes (Grade II) by 12 1/2 lengths. Getting jockey Kent Desormeaux for the first time, Thirty Eight Go Go stayed close to the early leaders, then swept past them near the quarter-mile pole. She covered the 1 1/16 miles in 1:46 2/5 for a $30.40 win mutuel.

Thirty Eight Go Go likely will have to duplicate that pattern to win today. She hasn't the speed of Sham Say, illustrated in her 2 1/2-length defeat to the gray favorite in Pimlico's six-furlong Cameo Stakes Oct. 4.

"We didn't have any excuse in that race," Leatherbury said. "That was a shorter race, and Sham Say is awfully fast. The same situation is going to present itself {Saturday}. Sham Say is going to have the lead, and we've got to try to catch her."

Jockey Greg Hutton incurred a minor injury yesterday when his mount, Buck's Fantasy, apparently suffered a heart attack during the third race and threw Hutton over the inner rail. Buck's Fantasy, a 7-year-old gelding, died. Hutton was taken to Greater Laurel-Beltsville Hospital, received four stitches in his right leg and was released.

Favored at 5 to 2 over 10 other $5,000 claimers, Buck's Fantasy broke nicely in the six-furlong race, but began to fall behind within the first quarter-mile. As the leaders turned into the stretch, Buck's Fantasy was laboring in last place, whereupon Hutton began to ease him. "He started going real bad, and I was getting ready to pull him up," Hutton said. "But I couldn't stop him."

Buck's Fantasy staggered, then slammed into the inside fence near the 3/16th-mile pole. Hutton, standing in the stirrups, was hurled onto the soggy infield turf, his right leg striking the rail as he descended.

In addition to Hutton, jockey Gregg McCarron was hospitalized with strained back muscles incurred as he was pulling up Tzedekah after the second race. Hutton said he will ride today; McCarron will not.

In yesterday's feature race, Vincent Bracciale rallied Friendly Pete down the center of the track to defeat Sudden Flare by two lengths in a $16,000 allowance. He ran the six furlongs in 1:11 2/5.

Trainer John Mobberley has used jockey Mario Pino almost exclusively the last few years. But Mobberley named apprentice Bryan Antley to ride two horses yesterday.

"I just used {Antley} on those horses because they're a couple of cheap bums," Mobberley said. "They're rats, and I figured the seven pounds {less} couldn't hurt them. I'd put a chimpanzee on them if I could get 15 pounds {less}. Basically, I'm just trying to pull out all the stops.

"This has nothing to do with Mario's ability as a rider. There's absolutely no animosity -- ever -- between him and myself. We've been friends through thick and thin."

The fall meeting has been lean for Mobberley, who has won two of 31 races at Laurel.
