Rapport won her second consecutive race, and first against winners, in Wednesday's sixth race, scoring an easy victory by 4 3-4 lengths.
Ridden by Martin Garcia, Rapport led throughout and pulled clear to lead by five lengths at the eighth pole. A 3-year-old filly by Songandaprayer, she ran six furlongs in 1:08.99, giving trainer Bob Baffert his second winner of the day. He also finished second with Toro Bonito.
Rapport was comprehensively beaten in three starts last year at Churchill Downs and Saratoga for trainer D. Wayne Lukas, and joined Baffert's stable in the winter.
Earlier in the day, Baffert finished 1-2 with Premier Cru and Tweebster in a maiden race over 1 1-16 miles.
