Last year, she won the race by 2 1/2 lengths over Tout Charmant.The 6-year-old mare worked five furlongs on the track's turf course in :59.72 Sunday under Eddie Delahoussaye and trainer Julio Canani will wait to see how she comes out of the work before he decides on a start in the Palomar.Del Mar clocker John Fontaine timed Tranquility Lake's work in splits of :24.05 and :48.33.In her last start, Tranquility Lake won the Clement L. Hirsch Handicap (gr. II) on Del Mar's main track.

Her main goal remains a distaff race on the Breeders' Cup card – either the main-track Distaff or Filly and Mare Turf. Last year, she finished eighth in the Filly and Mare Turf.Others expected for the 1 1/16-mile Palomar are High Walden, Alex Solis to ride; Minor Details, Victor Espinoza; Paga, Mike Smith; and Tout Charmant, no rider named.
