Kent Hastings, Freestate Raceway's presiding judge, confirmed yesterday that the track's judges are investigating the ninth race Wednesday night. The race was won by Hue Kash, who showed unusual speed.

Hue Kash's driver, William Long, was to meet with the judges last night. The horse's owner and trainer, Robert Short of Laurel, Del., will meet with the judges Saturday.

Hastings said he is investigating the race because "the horse went about six seconds faster than in his last start." Hastings said the hearings would include a look at the betting patterns in the race and a view of films from Hue Kash's previous races.

Hastings said he received three phone calls this morning complaining about the race and that Freestate's racing secretary, Ted Leonard, received four calls.

Long and Short were not available to comment.

Hue Kash won the mile race, a $5,000 claiming event, in 1:57 4/5 on a racing surface listed as good. In the previous race, an $8,000 claimer with supposedly superior horses, the winning time was 2:01 1/5.

Hue Kash's time was his lifetime best. He has been racing mostly in $6,000 claiming events the past two months. The 8-year-old's previous best was a 1:59 at Roosevelt Raceway in 1982.

Hue Kash went off at 6.60 to 1 Wednesday and paid $15.20. He was listed as 6 to 1 in the morning line. The exacta (7-6) with Hue Kash and the race's long shot, (14.90 to 1) Buck Frost, paid $154.

Hue Kash won the race in a fashion usually reserved for top-quality pacers. He led from start to finish, with quarter-mile fractions of :28 2/5, :57 4/5 and 1:26 2/5. His winning margin was seven lengths.

In his last start, May 23 in a $6,000 claimer, also on a good track, his race fractions were :29, 1:00 1/5, 1:30 and 2:03 3/5. He finished last, 11 1/4 lengths behind the winner.
