This one's a biggie for 'Ivana'


MIAMI - Ivanavinalot has already won the Grade 2 Bonnie Miss Stakes and competed against the best of her division in the Ashland and Black-Eyed Susan Stakes this season. But the queen of the local 3-year-old division may be making her most important start of the year when she returns home against six other 3-year-old fillies in Saturday's $100,000 Office Queen Stakes at Calder.

The 1 1/16-mile Office Queen will serve as the feature race on a 13-race card that also includes the $40,000 Linear Handicap, scheduled to be run at five furlongs on the turf.

Ivanavinalot is coming off subpar performances in both the Ashland and Black-Eyed Susan. While she had excuses in both races, there is some question as to whether Ivanavinalot is the same filly who proved so dominant here at 2 and when she posted a 1 3/4-length victory over My Boston Gal in the Bonnie Miss on March 14.

"This is definitely a very important race for her," said her trainer, Kathleen O'Connell. "We'll both be looking to redeem ourselves on Saturday."

Ivanavinalot had a legitimate excuse in the Ashland after being severely roughed up leaving the gate by the winner, Elloluv. She chased the pace for six furlongs before finishing a badly beaten fourth over a sloppy and slick racetrack at Pimlico in the Black-Eyed Susan.

"I think she's still as good now as she was when she won the Bonnie Miss," said O'Connell, "and if she runs her race she should win on Saturday."

At 2, Ivanavinalot easily handled her two chief rivals in the Office Queen, Dakota Light and Running Debate.

Dakota Light finished second and then third, beaten five and 15 1/2 lengths by Ivanavinalot in both the Brave Raj and My Dear Girl stakes last summer. But Dakota Light has shown marked improvement since those meetings and is coming off a 2 3/4-length victory in the one-mile Raviola Stakes here on May 25. She was also graded stakes placed earlier this season, beaten a half-length by the odds-on Ebony Breeze in the Grade 3 Florida Oaks.

Running Debate finished a well-beaten fourth behind Ivanavinalot in the seven-furlong Susan's Girl at 2 but has also been much improved since that encounter. Her most important victory came in the OBS Championship Stakes on March 17.

If the Linear goes on the grass as scheduled, My Girl Lisa, who has already won a pair of turf stakes against males, may prove the one to catch. Her chief rivals could be Callthesheriff, beaten just a neck in a division of the Blazing Sword Stakes in his last start, and Tour of the Cat.

Tour of the Cat, the premier main-track sprinter here last season, has not started since finishing seventh in the Artax Handicap on April 5. He upset Burning Roma and Highway Prospector to win the Grade 2 Richter Scale Breeders' Cup Handicap in his previous start and is equally adept on turf as on dirt.
