SARATOGA SPRINGS, N.Y. - On Fire Baby, winner of the Grade 1 Apple Blossom in April, and Authenticity, winner of the Grade  3 Shuvee last out, head the list of competitors scheduled to face Royal Delta in Sunday's Grade 1, $600,000 Personal Ensign Invitational at 1 1/8 miles. On Fire Baby has not run since finishing second, beaten a head by Authenticity, in the Grade 2 La Troienne on May 3. On Fire Baby was entered in the Fleur de Lis at Churchill Downs in June, but scratched because of a virus. "She's going great now," trainer Gary Hartlage said. "I hope she comes up here and runs the race of her life. She's going to have to." On Fire Baby will break from the rail under Joe Johnson at 118 pounds. Royal Delta, recent 10  3/4-length winner of the Grade  1 Delaware Park Handicap, drew post  2 and will carry 124 pounds. Open Water (114), Centring (114), and Authenticity (118) complete the field. The Personal Ensign, run at 1 1/8 miles, is a "Win and You're In" race for the Breeders' Cup Distaff. [BREEDERS' CUP CHALLENGE: Win and You’re In schedule and results]
