Even though he lost his bid for the Triple Crown when he was defeated at the Preakness, Kentucky Derby winner Animal Kingdom will race at this year’s Belmont according to SI.com.

There were some questioning whether or not trainer Graham Motion would hold Animal Kingdom out of the Belmont (June 11) after Shackleford held him off down the stretch at the Preakness. But apparently the 3-year-old colt is a “go” for the third leg of the Triple Crown.

Preakness winner Shackleford is not yet a definite for the final leg of the Triple Crown. Trainer Dale Romans says he wants to wait a few days before deciding.

The last rematch in the Belmont between the Derby and Preakness winners was 2005, when Preakness winner Afleet Alex defeated Derby winner Giacomo.

Animal Kingdom will attempt to become the 12th horse to complete a Derby-Belmont double.

Even though Shackleford beat Animal Kingdom at Pimlico two weeks ago, I would think most horseracing observers would consider Nehro to be Animal Kingdom’s main threat at the Belmont. Nehro had an impressive outing at the Kentucky Derby, where he finished second behind Animal Kingdom. He sat out of the Preakness, meaning he should be fresh for his running at Belmont Park in two weeks.

Of course, many people probably counted Shackleford out at the Preakness when track crewmembers had a though time loading him into his starting position. He set the pace at Churchill Downs before finishing fourth and then won at Pimlico. He cannot be counted out if he winds up running and I hope he does, because it should be a three-horse race between him, Animal Kingdom and Nehro at the Belmont.
