Representatives of a group that includes Washington Redskins lineman Mark May is scheduled to meet with representatives of harness track owner Mark Vogel today to discuss the possible purchase of Rosecroft Raceway and Delmarva Downs, according to sources.

May is not expected to attend the meeting with the group, members of which were not identified.

Earlier in the day, Vogel and his representatitves are scheduled to negotiate with a partnership that includes Alan Foreman, a horsemen's attorney from Baltimore.

May, contacted yesterday at Redskin Park, declined to discuss any aspect of his involvement regarding the pursuit of Rosecroft and Delmarva, Maryland's only harness tracks.

May owns about a dozen standardbreds in Maryland and Florida, including the stakes-winning 2-year-old Charlie Ten Hitch, and frequently attends the races at Rosecroft.

Several groups have expressed an interest in the harness tracks since Vogel announced they were for sale two months ago. Although rumors of a sale have escalated in recent days, Dan Sandler, Vogel's lawyer, said no deal had been made as of yesterday afternoon.

Sandler refused to comment on today's meetings, and Vogel declined to comment altogether. Curran Takes Over Mike

Delaware Park announcer John Curran will call the races at Laurel from Dec. 26 until the meet ends March 13, General Manager Jim Mango said.

Jehan Malherbe, who has called Laurel's races this month, will work here through Sunday before returning to South Africa for the height of the racing season there. Laurel officials are scheduled to meet with Malherbe today to discuss the prospect of his returning this spring; meanwhile, they have about 40 tapes to consider from others seeking the full-time announcer's job after Curran departs. . . .

Safely Home, the dam of champion sprinter Safely Kept, will be bred to the brilliant English colt Dayjur, according to owner David Hayden. Safely Kept defeated Dayjur in the memorable Breeders' Cup Sprint after Dayjur twice jumped shadows and lost the lead near the wire. Dayjur stands at Shadwell Farm in Kentucky for a live-foal fee $50,000. Hayden said he wants to name the foal Beyond The Shadow. . . .

The double-triple pool dissolved into 13 parcels of $4,943.70 when a 258-1 shot, Hard To Swallow, finished third in the third race. Because no one used Hard To Swallow (No. 11) in triple combinations with Alamance (3) and Lord Hugh (4), any tickets with 3 and 4 in the first two positions were considered first-half winners because the first half of the double triple requires a payout. Each of those paid $17.70.

Hard To Swallow, who hadn't been within 10 lengths of a win in six starts at a mile track, led until the far turn and held on for third. He finished 20 lengths behind Alamance and paid $99.20 to show. . . .
