Jockey Edgar Prado rose and fell yesterday at Laurel and ended the afternoon in limbo.

Prado has started slowly this meeting, and just when he appeared to break the mini-slump, down he went in two uncomfortable ways.

Only three for 41 when the day began, Prado guided the unraced Hush Hush Indian to an front-running victory in the second race, then rallied Sweet Alex from back in the pack to win the fourth.

In the following race, he didn't get far. Chris Farrell's misstep in his first stride sent Prado somersaulting over the colt's right shoulder.

While Prado was being examined in the first-aid station, trainer Carroll Hawkins scrambled to find a rider for With Intent in the sixth race. Andrea Seefeldt replaced Prado and rode the horse to victory.

With a mild ache in his rib cage, Prado returned for the seventh race and by the ninth had a third winner in his grasp -- until it was stripped away. He pushed another of Hawkins's horses, My Three Daughters, to victory in the $23,000 allowance feature but had too much contact with Bearskin Rug in the stretch. Jockey Gregg McCarron claimed foul, and My Three Daughters was disqualified and placed sixth.

Stewards will determine whether a suspension is warranted for carelessness on My Three Daughters. Prado is riding on a stay from New Hampshire, where Wind Splitter was disqualified from fifth in Sunday's Father Day Handicap at Rockingham Park. Medication Information

The Daily Racing Form will include Lasix and Butazolidin information in its charts and past performance lines beginning July 1 in jurisdictions that permit the medications, the publication announced yesterday.

In listing past performances, the Form will use the letters L and B to denote the medications, to the right of the jockey's name. Medication information will be furnished by tracks and applied to races run July 1 and later.

Lasix, the medication that controls respiratory bleeding, can produce a dramatic improvement in horses, especially when first administered. In their programs, Laurel and Pimlico list the date each horse on the card first received Lasix in Maryland, and Jim Mango, vice president-director of operations, said that isn't likely to change.

"Everybody who buys a program doesn't necessarily buy a Racing Form," Mango said. "If we were not to provide the information, I think that would go against what we're trying to do." . . .

Highland Devotion, a 3-year-old who ran exclusively in claiming races until this spring, is a strong early favorite in today's $75,000 Governor's Cup at Laurel.

Since trainer Bob Klesaris claimed him for $45,000 in March and put him on turf, Highland Devotion has won two races and been nosed out of a victory in his other try. The Northrop gelding has six to beat in the 1 1/16-mile turf race.
