Colt Enterprises, owner of the state's two harness tracks, is seeking a longer 1993 racing season.
Tom Barry, general manager of Rosecroft and Delmarva raceways, is expected to ask the Maryland Racing Commission today for earlier openings next year for the tracks.
The commission meets at Timonium to discuss the harness dates, but will not award either 1993 harness or thoroughbred dates until its November meeting.
Rosecroft management is asking for 233 nights, an increase of 32 from 1992, and permission to open Jan. 6. Dates at Delmarva Downs would increase from 87 nights this year to 93 nights in 1993. Delmarva would open April 2.
Barry said that Rosecroft hopes to open earlier in order to continue to simulcast races from New Jersey, a move that already has boosted the handle 18 percent in just the first
week of the simulcasting experiment.
The earlier Delmarva opening would accommodate horsemen who ship there after the Dover Downs meet in Dover, Del., closes.
Laurel-Pimlico operator Joe De Francis said he anticipates no major changes in the 1993 thoroughbred schedule, except that the Pimlico spring meet might close earlier and then the Pimlico fall meet would open earlier, similar to the 1990 format.
