June 2 (UPI) -- A field of eight is set for the Saturday's Grade I Belmont Stakes, the third leg of the Triple Crown, with several of the 3-year-olds looking to improve on their performance in the Kentucky Derby.

Not only will there will be no Triple Crown sweep this year after Medina Spirit won the Run for the Roses and Rombauer took the Preakness Stakes, but the makeup of the Belmont field means not a single horse will have competed in all three races.

Medina Spirit, whose Derby victory is in doubt after a positive post-race drug test, did not contest the Preakness and is not entered for the Belmont.

Rombauer did not run in the Derby, and then posted an upset win in the Preakness. He is the second choice on the Belmont morning line at 3-1, but the favorite is Essential Quality at 2-1.
