The work, with exercise rider Simon Harris aboard, was the second-fastest of 20 at the distance. It was almost three seconds faster than Bernardini's five-furlong move last Friday, which went in 1:03.48. Bernardini, who followed his Preakness win with a nine-length win in the Jim Dandy on July 31, is being prepared for a start in the $1 million Travers on Aug. 26.

Harris let Bernardini get a strong run-up to the five-furlong pole, and Bernardini was timed in fractions of 12.75 seconds, 24.86, 37.03, and he got his last quarter in 23.71 seconds. He galloped out six furlongs in 1:13.63 and went out a mile in 1:41.64.

"I wanted him to do more today," said Albertrani, who watched the work atop his stable pony. "I told Simon to be sure to let him gallop out and get something out of it this time. It's really the last time we're going to put a strong work into him."

The main track has been extremely deep and demanding the last week, something Harris said he felt, but his horse didn't.

"From the quarter pole on he was taking me along, but I could feel the difference in the track," Harris said. "You know me, I stayed out wide again, but you can feel it. It's nothing to him."

Nice work for him
