Maryland harness racing fans were treated to one of the fastest trotting programs ever in the state Saturday night when some of the nation's top young standardbreds raced at Rosecroft in the Colonial for colts and the Colonial Lady for fillies.

According to Jerry Connors, Rosecroft's director of publicity, the 42-year history of Rosecroft had seen only nine trotting miles in 1:57 2/5 or better. Five more came Saturday night on Rosecroft's highly touted year-old five-eighth-mile oval.

The most impressive Colonial winner was Cheyenne Spur, a $100,000 yearling purchase of Roy Davis and Joseph Hardy.

Driven by Richard Stillings, Cheyenne Spur quickly pulled away from the field and trotted on to a 10 1/2-length victory in a lifetime best 1:56 2/5.

Light rain during the night made the track condition good.

"He did that on his own," said Stillings. "He wanted to trot. That's a fast track but it was a little sticky. That's a good record for him."

Cheyenne Spur earned half of the $122,033 purse for his effort.

In the other Colonial Trot for 3-year-old colts, Jeanne's Somolli, driven by Rod Allen, held off a strong challenge from Armbro Iliad and driver Mike Lachance to win in 1:56 4/5.

In the second Colonial Lady division, Happy Diamonds overcame a rough journey to win in 1:57, a new Rosecroft record for 3-year-old trotting fillies.

Rod Waples drove.

The first filly division went to Me Maggie and driver Berndt Lindstedt in 1:57 2/5.

Working Gal won the final filly division in 1:57 1/5 with Lachance driving.
