Speed figures: These are last week's 20 fastest stakes winners
My Mane Squeeze earned the highest Horse Racing Nation speed figure, 135, among last week's stakes winners for her victory in the Johnstone at Saratoga on Wednesday.
With Luis Saez riding, the 4-year-old Audible filly led gate to wire to win the seven-furlong dirt race by 6 1/4 lengths. Her win in the black-type race followed four consecutive losses, all in graded stakes.
My Mane Squeeze also got a 102 Brisnet Speed Rating and 100 Beyer Speed Figure for her performance.
Seismic Beauty, the Bob Baffert filly who won the Clement L. Hirsch (G1) at Del Mar for her third straight victory, was next on the list with a 134 HRN figure, followed by Whitney (G1) winner Sierra Leone with a 132.
