Sam Pollock's Seven Four Seven, the 2-1 favorite under leading rider Jason Lumpkins, , overpowered 10 rivals entering the home stretch and rolled to a 4 1/2-length win in the $50,000 Likely Exchange Stakes for fillies and mares Saturday at Turfway Park.

"Other than the break, everything went perfect," Lumpkins said after winning his fourth consecutive stakes of the winter-spring meet. "I didn't rush her. I let her settle where she wanted. She started picking up horses down the backstretch, and I could tell I had a ton of horse. She acted very professional today, and it paid off with an impressive win."

Seven Four Seven, 5, trained by Turfway's leading conditioner, Bernie Flint, improved her record to 8-7-4 in 30 starts with earnings of $296,888. It was her sixth victory at Turfway in 12 starts.

Mary Doser joined an elite list of female riders when she collected her 1,000th career win aboard October Optimist, trained by Chris Dorris, in the eighth race. Doser is the 14th female thoroughbred jockey to reach the milestone.

"You don't ever think you'll get there," Doser said. "This is great. Things have been falling into place. It would have been nice to have won it the other night with (husband/trainer) Scott (Sowle), but I love Chris. I used to babysit for him."

Hall of Famer Julie Krone tops all female riders with 3,582 career wins through Friday, followed by Patricia Cooksey, who has 2,131.

Others with 1,000 victories: Patti Barton, Donna Barton, Cindy Noll, Diane Nelson, Dodie Duys, Rosemary Homeister Jr., Vicky Arogon Baze, Vickie Warhol, Jill Jellison, Lillian Kuykendall and Lori Wydick.

Doser, former leading apprentice at Ellis Park in 1986, won her first race that year at River Downs.
