The thoroughbred racing scene shifts from Pimlico to Laurel Monday and several changes will be in effect for the 48-day meeting that ends July 19.

New post time for the first race will be 2 p.m. There will be only one general admission charge of $3 and the finish line will be located a sixteenth of a mile farther down the stretch.

Freestate closed out its 30-day meeting last night with a total handle of $14,073,233 for a nightly average of $469,107. Total attendance was 137,076 for an average of 4,588.

Maryland harness racing will shift from Freestate to Rosecroft Monday night. Rosecroft's second meet of the year will cover 46 nights with racing through Thursday, July 15. Post time is 8 o'clock.

At Laurel, the opening day feature will be the $35,000-added The Very One Stakes for 3-year-old fillies going 1 1/16 miles over the turf course. The inaugural running of the stakes, named for the popular mare owned by Helen Polinger, has attracted 15 starters, including the coupling of Hat Tab Girl and Malapropism of the Happy Valley Farm stable.

Honed Edge and Smart Heiress are expected to be favored.

Laurel's meeting will be for 48 racing days and will run through July 19.

Pimlico, which closed today, showed a slight drop in attendance and mutuel handle for its 1982 season. Its final feature was the $30,000-added Nellie Morse Handicap won by the heavily favored Poquita Fe, a 6-year-old mare. It was her 29th victory in 36 career starts. The Panamanian-bred daughter of Apollo Streak has also finished second and third three times.

Trainer Ron Alfano led the Pimlico standings with 42 victories. Jockey Donald Miller Jr., who served a seven-day suspension and part of another at the meeting, was the leading jockey with 61 victories.

At Rosecroft, the highlight of the meet is expected to be Saturday night's William E. Miller Memorial Pace. This year's purse of $100,000 will make the Miller the richest Maryland harness race in history.

Sixty-six of the nation's best 3-year-old pacers are still eligible for the Miller. Two expected starters are Temujin, who set a world pacing record of 1:56 1/5 on Louisville Downs' half-mile track, and Apollo's Way, who won $350,148 as a 2-year-old.
