Tough to separate Plesa's fillies


MIAMI - Trainer Eddie Plesa Jr. appears to have the upper hand coming into Saturday's $50,000 Office Queen Stakes at Calder, where he will send out the uncoupled pair of Wander Mom and Sara's Success against 10 rivals in the 1 1/16-mile turf race for 3-year-old fillies.

Wander Mom and Sara's Success have already accounted for seven turf victories between them while the rest of the field combined has only won nine races on grass.

The pair also enters the Office Queen on a roll. Each filly has won her last two starts, including victories over the local surface earlier in the meet.

Wander Mom may wind up the slight choice after scoring a victory in Hialeah's Coconut Grove Stakes on April 29. She is also the richest member of the starting lineup with almost $120,000 for owner-breeder Jaime Carrion.

Sara's Success will be making her first start in the colors of the Thorobeam Farm, which purchased the filly privately shortly after her impressive 7 1/2-length allowance victory on May 27.

"It's really tough to separate the two fillies," said Plesa. "Wander Mom's past performances are probably a little more impressive since she is already a stakes winner. But Sara's Success seems to just be getting better with every start and she likes this turf course. Both also have similar running styles, although Wander Mom appears to have one kick to her while Sara's Success might be a little more versatile."

Although Wander Mom and Sara's Success will likely go off as the first and second choices in the betting there is not much separating the duo from several of the other major contenders in a race that includes Hasty Kiss, Free the Magic, Dispersed Reward, Frozen Dinner, Light Dancer, and Multiplicity.

Hasty Kiss has won her last two races. She has not started since rallying to a hard-fought neck victory over preliminary allowance company at Hialeah on May 20.

Free the Magic was stakes-placed twice on grass at Hialeah and finished less than a length behind Wander Mom under allowance conditions here two weeks ago.

Dispersed Reward was no match for Sara's Success last month but figures to move forward off the race, her first start in over six months. She was beaten a neck by Morning Sun in her only other turf appearance, a division of the Long Gone Blues Stakes, at 2
