Deputed Testamony, winner of the Preakness Stakes, has been scratched from today's $200,000-added Pennsylvania Derby at Keystone Race Course, trainer Bill Boniface said yesterday.

Boniface had entered both Deputed Testamony and Parfaitement as an entry in the 1 1/8-mile race, but Deputed Testamony drew the outside No. 12 post position and Parfaitement does not run well on an off track.

"The outside post position and the 12-horse field made up my mind for me. Parfaitement will also be scratched if the track is less than 'good,' " Boniface said from the family farm in Bel Air, Md.

According to sources at Pimlico Race Course in Baltimore, Boniface, whose stable has been remarkably successful the past two years, had tried to discourage the entry of Megaturn, a colt who was undefeated in four previous lifetime starts until he finished a fast-closing third in the Withers mile in his last race.

But yesterday, word came from Belmont Park that Megaturn would definitely bypass the Peter Pan Stakes there and was headed for Keystone.

Of Deputed Testamony, Boniface said, "The Belmont (Stakes) is only two weeks away; I would have liked to have a race in him but I'll work him good on the 31st. That should have him right on schedule."

With the scratch of Deputed Testamony, Megaturn appears to be the morning-line favorite. The main contention is expected to come from Bet Big, a speedy colt trained by Sonny Hine, and Current Hope, a gray son of Little Current who has not caught a fast track since winning the Flamingo Stakes at Hialeah last winter.

Current Hope was scratched from the Preakness when the track turned sloppy on Preakness Day; his stable indicated yesterday he would not run if Keystone has an off track today
