LOUISVILLE, Ky. – The entire cast for the 2010 Breeders’ Cup was on the grounds at Churchill Downs by Thursday morning, with all the preparations over, save for a few last-minute tweaks here and there that included several blowouts both over the main track and turf course. Once again, Zenyatta was the star of the training show, galloping 1 1/4 miles after spending about 10 minutes in the one-mile chute. She was obviously taken by the large assemblage of media and adoring fans who lined both the back and front side to watch her go, cocking her head outward so everybody could take advantage of the photo opportunity. She swapped leads briefly at the head of the stretch but jumped beautifully into a perfect lead change once re-entering the backstretch. The following horses blew out on Thursday. Deciphering Dreams (Juvenile Turf): With jockey Garrett Gomez up, he cruised an easy three furlongs in 38.17 seconds over the main track despite the fact he will run Saturday on turf. Goldikova (Mile): Two-time defending Mile champion was aggressive and under a tight hold galloping three furlongs down the stretch in 41.08. Behkabad (Turf): Group 1 winner open galloped three-eighths in 41.66, just in front of Goldlikova and looked good. Miss Keller (Filly and Mare Turf): Blew out a quarter-mile down the stretch on the turf in 24.66, galloped out three-eighths in 39.29. Societys Chairman (Mile): Blew out a quarter-mile down the stretch in 24.41, galloped out in 39.09 on the grass. Beethoven (Mile): Blew out an easy three-eighths in 37.04 on the turf, covering his final quarter in 23 and change. Master of Hounds (Juvenile Turf): Blew out three-eighths in 38.02 on the turf, but did not appear very comfortable over the local strip. Fancy Point (Juvenile Fillies Turf): Blew out a quarter-mile in 25.56 on the grass with Kent Desormeaux aboard, pulled up three-eighths in 39.58. Although I hadn’t seen enough of Harmonious to mention her in my Friday Clocker Report, she really caught my eye with perhaps the gallop of the day and should be added to the list of top contenders for the Filly and Mare Turf. Other gallopers included Jaycito, equipped in blinkers, for the Juvenile and Mad Flatter, who should be a huge pace presence in the Dirt Mile. Rightly So was really on the muscle, flying under the wire and around the clubhouse turn in 13 and change splits. She will have to relax a little better to carry her abundant speed seven-eighths in the Filly and Mare Sprint. I can understand why trainer Christophe Clement was eager to run Gio Ponti on the grass in the Mile and not on dirt in the Classic. He just did not look comfortable galloping on the main track.
