Undefeated Singing Susan led all the way in yesterday's $25,000-added Toddler Stakes at Laurel, defeating Evening Run by six lengths.

The victory was her fourth, and her third in stakes company.

Jockey Bill Passmore, who replaced regular rider Rudy Turcotte, who was released by trainer Bernie Bond earlier this week, said after the race: "This filly is all horse. She just enjoys running."

Singing Susan ran the six furlongs in 1:11 2/5 and paid $2.40. She earned $16,570 to bring her career winnings to nearly $100,000.

Earlier, J. Fred Colwill, state steward, moved to calm horsemen who faced loss of stable space by the decision of Pimlico and Bowie to close their tracks when Maryland racing shifts to Timonium Tuesday.

Colwill, acting for Robert Banning, Timonium's general manager and the racing commission chairman, arranged for the more than 400 horses to be stabled at the old Hagerstown Race Track in Western Maryland. The plan is for Timonium and the Horsemen's Benevolent and Protective Association to pay a stabling fee to the Hagerstown track of $2 daily per horse and to pay for the vanning of the horses the 75 miles to Timonium when they are entered to run.
