A SUPER BOWL ATMOSPHERE AT HOLLYPARK.

Byline: Kevin Modesti Daily News Staff Writer

Before the first of the more than 600 handicapping puzzles scheduled for Hollywood Park's season, there was another mystery to be solved on opening night:

What do cheerleaders do at a racetrack?

It turns out the Hollywood Starlets, the Inglewood track's new Laker Girls-style dance troupe, don't even cheer for the horses. Their first official act was to throw Cigar T-shirts to the crowd estimated at 32,000.

Cheerleaders. The now-traditional Friday-night band music. Bo Derek, on horseback, leading a post parade. A huge cologne billboard obscuring views of the backstretch. Between-race prize drawings. . . .

What was the first clue we weren't at prim, proper Santa Anita anymore?

Maybe it was the fact that the first two sprints were won from the outside post position, evidence of the familiar Hollypark main-track bias.

That bias was expected to help favored Abaginone in the Los Angeles Handicap late on the card, the first of 67 this spring and summer.

Track management is already advertising Hollypark's role in hosting the Nov. 8, 1997 Breeders' Cup, with signs on the tote board and every available parking-lot fence.

And it's trying to enhance thoroughbred racing's biggest event by winning a schedule change permitting Hollypark to hold Breeders' Cup preps.

The change, being pushed by California Horse Racing Board chairman Ralph Scurfield and vice chairman Don Valpredo, would allow Hollypark to open for the last three Friday nights and Saturday afternoons of September 1997. To protect Fairplex Park, which will be open at that time, Hollypark will have to hold half of its races on turf and hold no claiming races.

Track president Don Robbins said the races would be written with Breeders' Cup hopefuls in mind, and that could bring out-of-state horses to California earlier than usual.

``People are going to want to try their horses over the Hollywood Park dirt track and turf course before they rush into the Breeders' Cup,'' Robbins said.

The proposed calendar will be considered at a CHRB Racing Dates Committee meeting next month.

Notes: Trainer Marty Jones, taking over from his father Gary, makes his stakes debut with the favorite in this afternoon's Senorita Stakes. Gastronomical is 3-1 on the morning line against a dozen other 3-year-old fillies on turf. . . . Marty Jones, 24, may have a rougher time Sunday when Tricky Code faces Track Gal, Cat's Cradle, Klassy Kim and Igotrhythm in the A Gleam, a sprint handicap for fillies and mares. . . .
