Conceding at least 4lb to her six rivals in the $600,000 contest, the Breeders' Cup Distaff winner took the lead at the top of the stretch before drawing away to score by two and a half lengths.

"She had a race under her belt this time and obviously off a lay-off last time out she still ran a great race," said her rider John Velazquez.

"Steve told me she was ready and she showed it. That was a great effort from her."

The daughter of Tapit has now won nine of her 13 career starts, including five Grade 1 races.
