Rosecroft Raceway officials have launched an investigation into Sunday night's 10th race, for which the exacta paid considerably less than the payoff on the winning horse.

The race was won by J C's Prince, who paid $28.40 for a $2 win ticket. My Old Man, the 1.10-to-1 favorite, finished second, a neck behind. The exacta (4 and 1) returned $19.80. J C's Prince was driven by Joe Dugan Jr. and My Old Man was driven by Mark Gray.

Since correctly selecting an exacta -- the top two finishers in order -- is so much harder than just picking the winner of the race, it is very rare for the exacta to pay less than the win price. Thus the officials' prompt move to investigate.

"We will work with the commission and judges to fully review the race," said Jim Murphy, Rosecroft's president and general manager. He said computer printouts showing the wagering pattern on the race were turned over to presiding judge Gary McCarthy Sunday night. Murphy said McCarthy already had scheduled hearings on the matter.

McCarthy could not be reached for comment yesterday.

After the race, Rosecroft judges posted inquiries to review two incidents in the stretch.

One found third-place finisher H H Cinder and driver Eddie Davis had interfered with Kehaar Timmy after H H Cinder broke stride. The judges disqualified H H Cinder and placed him fifth.

The judges also reviewed Mark Gray's drive behind My Old Man, who bore out in the stretch. But they found no violation of racing rules and let My Old Man's second place stand.

While agreeing that an investigation was warranted, Murphy cautioned that there were mitigating circumstances regarding Sunday night's payoffs. The total amount bet on the program was only $296,416, one of the year's lowest handles. Thus mutuel pools were small and any large wager could have a huge effect on payoffs.

"One wager that normally wouldn't impact the odds, will," said Murphy, who added, "The win pool was almost nothing."
