Todd Pletcher may be one of the most well-known horse trainers in the world, but he’s still looking for his first win in the Kentucky Derby. In 13 tries Pletcher has come up short each time, but with a large number of Derby contenders this year Pletcher could finally have a winner on his hands.

There are six horses that Pletcher has trained that could be among the 20-horse field in this year’s Derby. These six possible champion thoroughbreds include Any Given Saturday, Circular Quay, King of the Roxy, Sam P., Scat Daddy and Cowtown Cat.

The favorite out of that spectacular field appears to be Scat Daddy. The three-year-old colt started off the season slow with a third-place finish in the Holy Bull Stakes, before posting back-to-back dominant wins in the Fountain of Youth Stakes and the Florida Derby late last month.

If Scat Daddy isn’t the one to finally bring Pletcher a Derby win, the next two stallions to keep a close eye on are King of Roxy and Any Given Saturday. King of Roxy won by 7 ½ lengths in the Hutcheson Stakes and was narrowly defeated when he finished second at the Santa Anita Derby. Any Given Saturday showed his speed in his 2 ¾ length win in the Sam F. Davis Stakes, but has had a couple of disappointments since then with a second-place finish in the Tampa Bay Derby and a third-place finish in the Wood Memorial Stakes.

Even if those three strong contenders falter, Pletcher still has three strong horses left that could pull off an upset. Cowtown Cat made a strong case for himself as a real dark horse by winning the Illinois Derby last week, while Circular Quay also has a big victory to his name this season in the Louisiana Derby. Sam P. may be a long shot after has seeing his stock drop a little bit after failing to secure a victory in the Holy Bull Stakes (4th), Robert B. Lewis Stakes (2nd) and Santa Anita Derby (3rd).
