2015 Preakness Stakes action

BALTIMORE (AP) -- American Pharoah won the Kentucky Derby, yet didn't look unbeatable, as he had in his previous races. His trainer says he struggled. His jockey went to the whip about 30 times to urge him on in the stretch. His owner says the Derby wasn't even close to his best effort.

And now it's time for the Preakness, where a victory Saturday would set up American Pharoah for a Triple Crown chance at the Belmont Stakes in three weeks. It also would give trainer Bob Baffert an unprecedented fourth Triple try.
