Many horses on the Maryland circuit race successfully elsewhere in the country, especially those with a claiming tag. That tradition has been upheld the past weeks with the successful invasion of New York by top sprinter Star De Naskra and the router Quiet Jay.

But the most significant development has been the amazing success of Dom Alario, That's A Nice and Calderina.

The first left Maryland after being soundly whipped by the filly, The Very One, and was beaten in a three-horse photo for top money in Hollywood Park's Invitational Handicap, a race worth $250,000.

That's A Nice left the area after being defeated by the same lightly regarded filly and headed Calderina in the $75,000 Washington Park Handicap in Chicago. A fair conclusion would be that The Very One could get an invitation to the Washington, D.C. International should she hold her current form.

Coastal, winner of the Peter Pan at Belmont Park in 1:47 for the 1 1/18 miles, is an unlikely starter for the Belmont Stakes June 9, his trainer apparently choosing to duck Spectacular Bid until Coastal is given more seasoning. Should the extremely talented son of Majestic Prince be supplemented to the 1 1/2-mile classic, the starting fee will be $20,000.

The bill increasing the takeout of Maryland's tracks and breeders was signed into law Wednesday by Gov. Harry Hughes. The new arrangement had been approved by the Senate, 35-6, than by the General Assembly, 102-0. The tracks and breeders will receive 4.16 percent of the takeout instead of 3.41 with the state relinquishing the difference.

Several horses, including Dress Ship, winner of three races in succession, have shown remarkable improvement when given Lasix and/or Butazolidin for the first time.

Dress Ship was given Bute for the first time April 26 and has been unbeatable since. The 3-year-old filly had finished second and third in two previous career starts without the medication.

Wednesday Cappy's Image, a 21-to-1 chance, was given medication for the first time and won going away.
