Eblouissante, a 4-year-old half-sister to 2010 Horse of the Year Zenyatta, may have her stakes debut postponed after being diagnosed with a bruised foot following a win in an optional claimer last month. Trainer John Shirreffs said that Eblouissante recently resumed galloping after a brief break. He was unsure whether Eblouissante could start in the $300,000 Santa Margarita Invitational over 1 1/8 miles on March 16. “I think we’ll have to wait and see how she works,” Shirreffs said. “We’ll gallop her a week before we work her and get her back in her routine.” Owned by breeder Eric Kronfeld, Eblouissante has won her first two starts, including a maiden race at Hollywood Park in November and an optional claimer at Santa Anita on Jan. 17.
