Rosecroft Raceway has banned three drivers and two others from the track, apparently for their suspected connection with a race on Dec. 6 that was investigated by judges because of irregular betting patterns.

In separate action from any judges' rulings, Rosecroft's president and general manager, William E. Miller II, confirmed that drivers Tom Jackson, J.T. House Jr. and Rob Moffett, along with track patrons Duane Mitchell and Howard Cohen, have been excluded from the track indefinitely. Miller declined to comment on why the five were banned.

When reached for comment yesterday, all three drivers said they believe their exclusions from Rosecroft arose from their participation in the fifth race on Dec. 6.

Rosecroft judges investigated that race because of an irregular betting pattern and after being tipped that an individual had made large exacta wagers primarily keying on the horse Shadydale Frenetic.

The investigation resulted in only one 10-day suspension handed to driver John Marsh for what was judged to be a lack of effort in driving 4-to-5 favorite Townsend Hanover, who finished third. Marsh appealed the ruling but no date has been set for the hearing. Rosecroft has not taken any action against Marsh.

The race was won by Lord Teddie, who was driven by House and paid $23.60 to win. Shadydale Frenetic, driven by Moffett, finished second as the third choice. Jackson drove Blue Pasadena, who finished fifth as the 3-to-1 second choice. The 4-3 exacta returned $78.80.

All three drivers said they were surprised when notified by mail by Rosecroft that they were no longer allowed on track grounds. The three said the letter gave no reason for the exclusions.

Jackson, 22, the seventh-leading driver at Rosecroft last fall, said, "I felt I didn't do anything to deserve it."

House, 34, who has 12 years' racing experience, said the ban has knocked him out of harness racing. "I can't beat them, so I won't fight them," he said.
