BALTIMORE (AP) — It's shaping up to be the year of the females at the Preakness Stakes.

A filly is going to challenge the boys in the Run for the Black-Eyed Susans Saturday for the first time since 2009 when Rachel Alexandra won.

Ria Antonia will be ridden by Calvin Borel, who guided Rachel Alexandra to victory. Ria Antonia finished sixth in the Kentucky Oaks on May 2.

For the first time in the Preakness, a filly, a female jockey and a female trainer will all compete at the same time. Rosie Napravnik will ride Bayern while trainer Linda Rice will saddle Kid Cruz.
