This double is not as common, with only eleven horses completing it. Sometimes an injury will knock the Kentucky Derby winner out of the Triple Crown before the Belmont Stakes, or if he loses the Preakness his connections don't even go to the Belmont.

In the Derby, Middleground beat Hill Prince by 1-1/4 lengths. A week later, Hill Prince defeated Middleground by 1-1/2 lengths in the Withers. Middleground was bumped in the Preakness and chased Hill Prince, but pulled away to win by 5 lengths with Middleground 2nd. In the Belmont, Middleground beat Hill Prince who had run 10 days earlier in the Suburban.
In 1956 Needles was the first Florida-bred Kentucky Derby winner and national champion. Typically closing from 15 lengths or more off the pace, Needles won the Flamingo and the Florida Derby.

In 1963 Chateaugay was the champion 3-year old colt. He won the Kentucky Derby by 1-1/4 lengths and the Belmont Stakes by 2-1/2 lengths, but fell to Candy Spots (3rd Kentucky Derby and 2nd Belmont) by 3-1/2 lengths in the Preakness.
In 1972 Riva Ridge won the Hibiscus Stakes, ran 4th in the Everglades, then won the Blue Grass. He won the Kentucky Derby as the favorite by 3-3/4 lengths. In the Preakness, a pouring rainstorm and the mudder Bee Bee Bee conspired to produce a 4th place finish for Riva Ridge. Riva Ridge redeemed himself with a stirring 7-length victory in the Belmont, leading wire-to-wire.
In 1976 Bold Forbes won the Kentucky Derby and Belmont Stakes going wire-to-wire. He finished 3rd in the Preakness to Elocutionist (3rd Kentucky Derby bypassed Belmont). He also won the Saratoga Special and the Wood Memorial to become the champion 3-year old. He began his career in Puerto Rico, where he was champion 2-year-old. His Preakness loss was attributed to the furious push Honest Pleasure (2nd Kentucky Derby bypassed Belmont) gave from the start. In the Belmont, he survived was a 3-way photo finish to win.
In 1984 Swale was the champion 3-year old colt. He won the Kentucky Derby by 3-1/4 lengths and the Belmont Stakes by 4 lengths, but finished a well-beaten 7th in the Preakness to Gate Dancer (5th Kentucky Derby and 6th Belmont).

Thunder Gulch, finished a neck behind Oliver's Twist in third.
