Horses are never favored to win the triple crown. The triple crown is NOT a race - but the total of three races. They are the Kentucky Derby, the Preakness and the Belmont Stakes.
The colt I'll Have Another won the first two legs of the TC (Derby and Preakness) but was scratched from the Belmont the day before the race due to a bowed tendon. He has been retired from racing but is in excellent health.
Not the US Triple Crown. But he did win the UK Triple Crown.
Prior to Miguel Cabrera winning the triple crown in 2012, the last Detroit Tiger to win the award was Ty Cobb in 1909.
