Blackie Daw, a former claimer trained by King T. Leatherbury and ridden by Bill Passmore, took the lead at the eighth pole and then gamely withstood a challenge by favored Sunny Winters for a length victory in yesterday's $58,800 Preston M. Burch Handicap at Bowie Race Course.

Zvetlana, the lone filly in the field of 11, finished third.

"We were lucky," Leatherbury said. "Sunny Winters was having trouble just as Passmore got my horse in gear. We got the jump and won."

Jack Kaenel, who rode Sunny Winters, said, "I had to wait and wait for room, then had to take out and come around. We would have been closer if we had the room."

Blackie Daw was claimed for $22,000 last December. His victory yesterday brought his earnings to $145,000.

The dark bay colt ran the 1 1/16 miles over a fast track in 1:43 4/5. He paid $7.20 as the second choice of the crowd of 11,493. Yesterday's handle of $1,504,534 surprised even Bowie General Manager Al Karwacki.

"I can't believe that we did as much business as we did with the Orioles playing such a crucial game in Baltimore on a sunny afternoon," he said.

The Orioles' game was blacked out in both Washington and Baltimore.
