I'll Have Another will be the 31st horse to head into the Belmont Stakes with a chance to win the Triple Crown.

Since 1919, when Sir Barton became the first to win the Kentucky Derby, Preakness, and Belmont, only 11 horses have managed to sweep all three races, most recently in 1978 when Affirmed beat arch rival Alydar by a head in the "Test of the Champion."

Five years earlier, Secretariat became the first horse since Citation (1948) to win the Triple Crown, with his 31-length Belmont triumph ending a 25-year drought, and in 1977 Seattle Slew became the first undefeated Triple Crown winner with his Belmont victory running his record to 9-0.

Completing the roster of champions are Gallant Fox (1930), Omaha (1935), War Admiral (1937), Whirlaway (1941), Count Fleet (1943), and Assault (1946).

The Belmont has tripped up 19 Triple Crown hopefuls, most recently Big Brown, who did not finish behind longshot winner Da' Tara in 2008.

There were consecutive Triple Crown tries from 2002-2004, with War Emblem finishing eighth behind Sarava in 2002, Funny Cide coming in third behind Empire Maker in 2003, and Smarty Jones being caught by Birdstone in the shadow of the wire before a record 120,139 fans in 2004.

In 1997 and 1998, Bob Baffert-trained horses came up inches short of sweeping the series, with Silver Charm losing by three-quarters of a length to Touch Gold, and Real Quiet nosed out at the wire by Victory Gallop in a dramatic photo finish.

In 1999, Charismatic finished third behind Lemon Drop Kid.

Pensive (1944), Tim Tam (1958), Carry Back (1961), Northern Dancer (1964), Kauai King (1966), Forward Pass (1968), Majestic Prince (1969), Canonero II (1971), Spectacular Bid (1979), Pleasant Colony (1981), Alysheba (1987) and Sunday Silence (1989) also fell short in their quest for the Crown.

Burgoo King (1932) and Bold Venture (1936) won the Derby and the Preakness, but did not start in the Belmont.
