If any horse can upset favorite Grace Hall in Friday's Kentucky Oaks, it will be local favorite On Fire Baby.

Friday marks the 138th running of the race, a 1 1/8-mile affair conducted at the main track and worth a $1 million pot.

Grace Hall is the morning line favorite at 5-2 and won at Churchill Downs last year in the Spinaway last summer. Most recently, she achieved a 6 1/2-length win in the Gulfstreak Park Oaks.

Though On Fire Baby's odds are tied for second with Broadway Alibi at 4-1, she is looking more and more like a favorite after winning the Pocahontas and the Golden Rod at Churchill Downs in the fall. In her most recent start, she won the Honeybee at Oaklawn Park and is primed to overtake Grace Hall with the help of trainer Gary Hartlage and jockey Joe Johnson.
