Gigowatt set a stakes record in winning the final division of the Potomac Stakes for 2-year-old pacing colts at Rosecroft Raceway last night in 1:54 4/5. Keystone Fabulous set the old mark of 1:55 1/5 in 1988 when the Potomac was run at Freestate Raceway.

There were five divisions of the Potomac -- the first was worth $64,887 and the other four went for $66,387. Afternoon rains made the Rosecroft oval sloppy for the first division, but the track improved to good for the latter races.

Gigowatt ($25) laid back for most of the race, making his move in the stretch when driver Ron Waples found a hole between leaders to finish a nose in front of Tooter Scooter. Raffles Hanover finished third, another nose back, in the most exciting division.

Waples also won the first division with favorite Deal Breaker ($2.80), who took the early lead, lost it briefly to second betting choice Hello Almahurst after the quarter but regained the advantage before the half to pace to a 1:56 2/5 victory.

In the third division, Cambest ($8.40) beat Stormin Jesse by 6 1/2 lengths in 1:55 2/5 for his for his fifth victory in six starts this year. "He did it effortlessly," said driver Dave Rankin of Cambest's wire-to-wire victory.

In the second division, William Fahy rolled to the lead with race favorite Silky Stallone ($3.60) and coasted home in 1:56 1/5. "When you're the best you want to be on top," said Fahy. "I wish they were all this easy." Witsends Prodigy finished second, 3 1/4 lengths back.

The fourth division featured a stretch duel between favorite Razzle Dazzlem ($3.40) and second choice June's Baby. At the wire, Razzle Dazzlem, driven by Eddie Davis, was the winner by a head in 1:56 1/5.
