Primary Suspect arrives

Primary Suspect, shipped up from Florida by trainer Mark Hennig, sprung a mild upset in Saturday's Grade 3 Toboggan at Aqueduct, beating favored Shake You Down by 1 1/4 lengths.

OZONE PARK, N.Y. - When the precipitation began falling Friday night, trainer Mark Hennig thought he might have wasted a trip north with his developing sprinter Primary Suspect.

But it snowed rather than rained and Aqueduct's inner track was fast by post time of the Grade 3 Toboggan Handicap. Thus, conditions were ideal for Primary Suspect, who ran by odds-on favorite Shake You Down inside the three-sixteenths pole to win the $107,100 by 1 1/4 lengths. Shake You Down held second by a neck over Houston's Prayer.

Super Fuse, Papua, and Jets Fan completed the order of finish.

Hennig shipped Primary Suspect to Aqueduct from Florida after running into a buzz-saw named Forest Danger in an allowance race at Gulfstream Park. Hennig, who trains Primary Suspect for Lee Lewis, said he would have scratched Primary Suspect had the inner track come up wet. Primary Suspect's two worst races came over off tracks.

Primary Suspect, under Pablo Fragoso, chased Shake You Down through fractions of 22.86 and 45.66 seconds before challenging and passing him in the stretch. Primary Suspect, a 4-year-old son of Hennessy, covered the six furlongs in 1:09.47. He returned $9.20 as the third betting choice in a six-horse field that had only four betting interests.

"I told [Fragoso] just try not to let him get away from you," Hennig said. "It's not necessarily the way he wants to be ridden - at the three-eighths pole having to go to a drive - but he was able to wear him down."

Mike Luzzi, the jockey of Shake You Down, said his horse ran his race.

"The main thing with Shake You Down is to get him away from there, and he got away from there and got pretty comfortable down the backside,'' Luzzi said. "He was finishing just as strong as the winner.''

* High Peaks, under Norberto Arroyo, took control soon after the start and led all the way to win the $82,350 Broadway Handicap by one length over Travelator. It was 1 1/4 lengths back to Schemer in third.

High Peaks, a 4-year-old daughter of Peaks and Valleys trained by Tom Bush for Berkshire Stud, covered the six furlongs in 1:10.44 and returned $12.20 to win.
