Singing Susan will be the heavy favorite in today's $75,000-added Kindergarten Stakes, Bowie's next-to-last feature of its meeting that ends Monday.

Singing Susan is the bay daughter of Rollicking and won five straight races earlier this year before running second in the prestigious Spinaway Stakes at Saratoga. She was sold last month to Theodore M. Sabarese, a New Jersey computer executive, for a reported $900,000. Sabarese, 41, has spent more than $5 million in the past year on promising horses, mostly fillies.

Singing Susan was developed by local trainer Bernie Bond, but will be saddled today by Sabarese's trainer, John Parisella of New York. She will be ridden by Miguel Rivera and will carry top weight of 122 pounds.

Chief competition for Singing Susan is expected to come from Bemissed, winner of two of five career starts who is trained by Woody Stephens.

There are unconfirmed reports that Maryland's three mile tracks--Bowie, Laurel and Pimlico--will ask for 16 additional days for their current 60-day meeetings.

Laurel, which opens Tuesday, has asked for and received permission for a 12.30 p.m. post time. Sources say the new time is to accommodate the anticipated longer meetings that will be run at Bowie this winter.

For the past several years, the mile tracks have been alternately holding an extra meeeting of 48 days. Last summer, it was Laurel's turn. The proposed 16-day extension at each track would change that schedule.

Bright Talisman made it two straight wins at Bowie when he won the feature race yesterday by more than two lengths over Bronze Hill.

Bright Talisman was ridden by William Passmore and was timed in 1:11 1/5 for the six furlongs. He paid $4.80 and topped a 6-2 exacta worth $30.80.
