Southern Tradition improved her formidable turf record yesterday by winning the Martha Washington Handicap at Laurel. Her two-length victory over Starfield came on a day when the double-triple jackpot again went unclaimed, reaching $151,831.

The double triple has confounded bettors in 14 straight programs since Laurel began its meeting Sept. 20. Although more than $63,000 was pumped into the pool yesterday, the third-race order of 6-14-3 produced only six winning tickets, each worth $4,215.30. None of those was exchanged for the 5-8-12 combination in the fifth race.

Mike Luzzi was the day's riding star with four victories. That gave him the season lead until Edgar Prado pulled even with Southern Tradition's strong stretch run.

On a firm turf course, the grayish filly turned three-wide into the lane and overpowered Charnell's Dream and McKilts for her fourth victory in 11 starts this year. Starfield, who had followed Southern Tradition past the tiring front-runners, held second by nearly a length over Secret Advice.

Southern Tradition has been first or second nine straight times and has never finished worse than third in 14 career turf outings. Trained by Henry Carroll, the New York-based filly ran 1 1/16 miles in 1:40 2/5 -- a second off the course mark -- and paid $5.60 as the favorite in a field of eight.
