BALTIMORE, SEPT. 16 -- Trainer Howard Wolfendale will win $1,000 Tuesday without saddling a horse.

A victory by Lisa's Halo in today's second race at Pimlico gave Wolfendale an insurmountable lead as the meeting's top percentage trainer.

After 33 days, Wolfendale has won at a 35.7 percent rate (10 of 28). Mert Bailes is second at 35.3 percent (six of 17), but neither he nor Wolfendale has a horse entered Tuesday, the final racing day of the year at Pimlico.

Among jockeys, Gregg McCarron (23.5 percent) has the lead, and only newcomer Rick Wilson can catch him.

Wilson, zero for three today, would need to win with one of his two scheduled mounts Tuesday to take the title. The win percentage leader among riders and trainers earns a $1,000 bonus.

Edgar Prado long ago clinched the riding title with 51 winners. Trainer King Leatherbury secured another meet title with 15 wins, three more than Fran Campitelli. A $53,811 Hitter

An unidentified man from Baltimore hit the double-triple for $53,811. The track guarantees a payout on Tuesday, but following today's score that distribution will be considerably reduced. Stacy in the Clear

The stewards met with jockey Allen Stacy to discuss Saturday's 10th race, in which Stacy restrained favored Sugarcone just as the filly was about to overtake Con Hielo near the finish; she ended up third. Stacy restated that Sugarcone felt as if she had broken down deep into the stretch, and the stewards said they were satisfied with the explanation.

"I've had that happen to me," said steward Bill Passmore, who won more than 3,500 races as a rider. "You'd swear a horse has broken down, but then they gallop out fine. It's a frustrating thing."

Trainer Berkley Kern had no comment on the horse's condition.

The stewards scheduled a conference with jockeys Michael Hunter and Frank Douglas for Tuesday morning to determine why Douglas intentionally struck Hunter on the right arm with his whip after their horses passed the wire in today's eighth race. Land Lord in Groove

Land Lord, a speedy 3-year-old trained by Ron Alfano, won his third straight sprint in familiar wire-to-wire fashion. Land Lord handled a muddy track to take the $19,000 allowance feature by almost three lengths over Tacoboy. Raines Settles In

After Timely Warning and Master Speaker took the top two spots in the Maryland Classic last Sunday, trainer Buddy Raines settled on keeping his eight-horse stable in Maryland for the fall. He seems intent on spending the time productively; Abduction won by a head-bob over Tormentada in today's fifth race (the closing half of the double-triple) for maiden claimers. Late in November, Raines plans to ship his horses to Aiken, S.C., for the winter. . . .

Apprentice Calixto Juarez was shaken up in a seventh-race spill today, then got an added pain in the next race when his replacement, Paul Nicol, rode Boundless Bou to victory. The $74.20 win mutuel was the biggest of the day. . . .

Klassy Briefcase, a New Jersey-based mare, goes after her fourth straight victory Tuesday in the $40,000-added Park Heights Handicap. Klassy Briefcase was assigned 124 pounds for the five-furlong turf race; Kathleen The Queen is weighted second at 118.
