Monomoy Girl, the four-time Grade 1 winning 3-year-old filly, worked a half-mile in 49.93 seconds Saturday morning over the Saratoga main track. She is preparing for a start in the Grade 1, $1 million Cotillion at Parx on Sept. 22.

With Florent Geroux up, Monomoy Girl, started about 1 1-2 lengths back of stablemate Purely Lucky. She tracked that one through a quarter in 24.42 seconds and gradually got to her workmate by the wire. The pair galloped out five furlongs in 1:03.26.

The work was the first for Monomoy Girl since she won the Grade 1 Coaching Club American Oaks at Saratoga on July 22.

Monomoy Girl is expected to ship to Churchill Downs in the next few days to continue her preparation for the Cotillion.

Monomoy Girl, trained by Brad Cox for an ownership group that includes Michael Dubb, Sol Kumin’s Monomoy Stable, Stuart Grant’s Elkstone Group and Michael Caruso’s Bethlehem Stables, is 8 for 9 lifetime. This year, she is 5 for 5 with Grade 1 victories in the Ashland, Kentucky Oaks, Acorn and CCA Oaks.
