Speed figures: These are last week's fastest stakes winners
Excellent Truth got the highest Horse Racing Nation speed figure among last week's U.S. stakes winners, earning a 123 for her repeat win in the Grade 1 Diana on Saturday at Saratoga.
After stalking the pace throughout, the 5-year-old daughter of Cotai Glory prevailed in a stretch duel and won by a head over odds-on favorite She Feels Pretty. Trained by Chad Brown and ridden by Flavien Prat, she completed the 1 1/8 miles on turf in 1:47.37.
She also received a 99 Brisnet Speed Rating and 102 Beyer Speed Figure, both highs for the week among U.S. stakes winners.
