Debby's Turn, a 5-year-old mare belonging to the Red Hill Farms, drew away from Silver Ice in the stretch yesterday to win the All Brandy Handicap at Laurel on the last program of the 1979 season.

The bay was ridden by Mario Pino and required 1:37 2/5 for the mile. The victory was her 26th in three years of racing and her 13th win in stakes races. The daughter of Turn To Mars has amassed a career total of more than $460,000. Yesterday's race was her last. She is scheduled to be bred to King Emperor next month.

Laurel, plagued by a washed-out track early in the meeting, closed its session with a daily attendance average of 8,592 customers, a rise of 4.1 percent over last year's figures. The biggest increase, however, came in the betting, where the average of $1,069,462 represented a rise of 9 percent.

The leading jockey was Pino, an apprentice, who closed the meeting with 93 victories. The leading trainer was Richard Dutrow with 36 wins. Bowl Game took home the most money, $120,000 while winning the $200,000 Washington, D.C. International.

Bowie, which opens today at 12:30 p.m., has hopes of racing on Jan. 27, the Sunday after the Super Bowl.

Bowie's 60-day meeting will open today with the $57,000 Resolution Handicap with 10 horses going 1-1/16 miles. Hempt's Lark, looking for his sixth consecutive victory should be the favorite.
