Essential Quality was set Tuesday as a 2-1 favorite for the Belmont Stakes, which will be run Saturday without a horse from trainer Bob Baffert pending an investigation into Medina Spirit's failed drug test after winning the Kentucky Derby. Preakness winner Rombauer and Essential Quality headline a field of eight horses for the third jewel of the Triple Crown. Baffert has no horses running at Belmont Park because the New York Racing Association suspended him in light of Medina Spirit's positive drug test for a corticosteroid at the Derby.
