Laurel Race Course will open its 60-day autumn meeting today with 13 horses entered in its traditional opening-day stake, the $60,000-added Laurel Turf Cup at 1 1/2 miles.

Laurel will have a new post time of 12:30 p.m. for the 10-week meeting.

There will be nearly $750,000 in stakes races within the first three weeks of the session, including the $200,000-added Laurel Futurity for 2-year-old males Saturday and a like amount for the Selima Stakes for 2-year-old fillies Oct. 30.

The highlight of the meeting will come with the 31st running of the Washington, D.C. International on Nov. 6.

Laurel's opening-day card drew 149 horses, the largest number of entries in memory of racing officials and railbirds, suggesting there is an ample supply of horses.

Bowie, which closed yesterday with a rise of 5.2 percent in the betting and 4.3 percent in attendance over last year, showed a mutuel handle of $973,936 on its final card.

Lady Dean, winner of her previous six starts at the track, made it seven straight by beating Zvetlana by a length in the $40,000-added Tosmah Handicap--mostly because of a ground-saving ride by Donald Miller.

Miller led the jockeys with 51 victories, 19 more than veteran Bill Passmore. Ron Alfano led King T. Leatherbury in the trainer's standings, 21 to 18.
