The 42nd running of the Middleburg Bowl, the second leg in point-to-point steeplechasing's triple crown, has drawn a field of seven and shapes up as the best timber race so far this season.

The 3 1/2-mile classic is the feature of an eight-race card at Glenwood Park, which opens with a turf (flat) race at 1 p.m. Sunday.

The Bowl, along with last Sunday's Rokeby Bowl, won by Don Yovanovch on Pidou II, and the Eustis Cup at Oatlands in mid-April, comprise the big three of Virginia steeplechasing.

The race will see the seasonal debut of two top Maryland horses, Frost Time and Sandi's prissey, both speedsters, front runners and indifferent to the 3 1/2-mile distance. From Pennsylvania is Juggernaut II, the nations number-two timber racer behind Dosdi last year. Also from Pennsylvania is Night Spot, a three-time winner over fences.

Randy Rouse's Summer Idyll, winner of the Warrenton Hunt Cup under Speedy Smithwick two weeks ago, will lead the Virginia contingent. George Ohrstrom's Martial Law, Ed Scott's Prompted and Mike DuPont's Olympic Run, which won the Oakley Plate at Piedmont in its first race over timber, round out the field.
