Authentic, the narrow winner of the Grade 1 Haskell Invitational on July 18 at Monmouth Park, had his third workout of August at Del Mar on Thursday in preparation for the Kentucky Derby on Sept. 5 at Churchill Downs.
Authentic worked six furlongs in 1:12.60. Earlier this month, Authentic worked a half-mile in 50.20 seconds on Aug. 1 and five furlongs in 1:03 on Aug. 8.
“I gave him a little company and gave him a little target,” trainer Bob Baffert said. “It was a good move. He went very well.”
