The 3-year-old colt, owned by WinStar Farm, was the 5-2 morning-line favorite in the 12-horse field for Saturday's $1 million, 1 3/16-mile race -- the second jewel in horse racing's Triple Crown.
Borel guided Super Saver to the Kentucky Derby win on a wet, muddy track, but he probably will have much better conditions to work with at the Preakness. A fast track is likely after forecasters called for a dry day with partly cloudy skies and a post-time temperature near 75 in Baltimore.
The top jockey is seeking his second straight Preakness win. Borel took last year's contest riding the filly Rachel Alexandra and has won three of the last four Triple Crown races on three different horses.
Trainer Todd Pletcher, who gained his first Kentucky Derby win with Super Saver after missing with 24 previous horses, is also looking for his initial Preakness victory.
