Trainer Saffie Joseph Jr. has wanted to try Soul of an Angel at seven furlongs from the time she joined his barn via a private purchase earlier this year. He finally gets that opportunity Saturday at Gulfsteam Park when sending Soul of an Angel out with an eye toward a potential start in the Breeders’ Cup Filly and Mare Sprint in the $220,000 Princess Rooney Invitational, the main event on the track’s spring-summer stakes schedule.
