1. 2006 Kentucky Derby: Barbaro's final victory
With a powerful 6 1/2-length victory, the largest winning margin since 1946, Barbaro proved he wasn't a one-surface pony. He became just the sixth undefeated horse in 132 years to win the Derby. The favorite heading into the Preakness two weeks later, Barbaro shattered his right hind leg, an injury that forced veterinarians to euthanize him around eight months later.
2. 2004 Kentucky Derby: Smarty Jones lives up to his pedigree
With Triple Crown winners Secretariat and Count Fleet and contenders Funny Cide and Fusaichi Pegasus in his pedigree, hopes were high for Smarty Jones in 2004. The 4-1 favorite started his Crown campaign in the muddy Kentucky Derby, maintaining his perfect race record and earning a 2 3/4-length victory after moving ahead at the top of the stretch. Smarty Jones won the Preakness Stakes by a record 11 1/2 lengths but was upset in the Belmont Stakes and finished second.
3. 2005 Kentucky Derby: Giacomo pulls off a shocker
Given 50-1 odds just before the Kentucky Derby, Giacomo surprised the field and became the second-biggest long shot to win the Run for the Roses. After breaking 18th out of the gate, Giacomo passed 17 horses in the last half-mile to edge out another 50-1 horse by a half-length for the victory.
4. 2009 Kentucky Derby: Mine That Bird goes from last to first
A 50-1 long shot surprised the field in the 135th running of the Kentucky Derby, as Mine That Bird exploded down the stretch for a 6 3/4-length victory. Squeezed immediately out of the starting gate, Mine That Bird fell about 15 lengths back in dead last early on. It was the second biggest upset in Derby history.
6. 2007 Kentucky Derby: Street Sense rallies at home
Street Sense earned a 2 1/2-length victory and became the first 2-year-old champion since 1979. A 9-2 favorite on his home track, Street Sense rallied from a position of second-to-last for the win. He later finished second in the Preakness and did not run in the Belmont Stakes.
7. 2010 Kentucky Derby: Super Saver gives Borel another win
Jockey Calvin Borel won his third Kentucky Derby in four years. The most wide-open Derby in years also gave trainer Todd Pletcher his first Derby victory after 24 losses by previous entries.
8. 2002 Kentucky Derby: War Emblem strong form start to finish
After taking the lead in the first quarter mile, War Emblem stayed up front on the 1 1/4-mile track and won by four lengths in 2002. The victory for the 21-to-1 long shot was even more surprising considering his jockey, Victor Espinoza, hadn't seen the horse until the morning of the race. War Emblem also won the Preakness, setting up a Triple Crown bid. At the Belmont Stakes, however, War Emblem stumbled out of the gate. While he briefly took the lead in the final turn, he had expended too much energy trying to catch up early and finished eighth.
9. 2003 Kentucky Derby: Funny Cide makes history
The first horse trainer Barclay Tagg ever ran in the Kentucky Derby turned out to be a winner, as Funny Cide raced to a 1 3/4-length victory in 2003. The first New York-bred horse to ever win the Derby, he also was the first gelding in 74 years to claim victory. Funny Cide cruised to a 9 3/4-length victory at the Preakness, the race's second-largest winning margin ever, but came in third at the Belmont Stakes.
10. 2008 Kentucky Derby: Big Brown runs away with the Roses
Making just his fourth career start, Big Brown overcame a tricky post position to win the Kentucky Derby by a commanding 4 3/4 lengths. Big Brown went on to win the Preakness Stakes by 5 1/4 lengths but came up well short in the Belmont Stakes, finishing last.
11. 2011 Kentucky Derby: New jockey rides Animal Kingdom to vitcory
Animal Kingdom raced ahead of Nehro and Mucho Macho Man to win the Kentucky Derby. John R. Velazquez replaced Robby Albarado on the winner after Albarado broke his nose earlier in the week. Animal Kingdom was a 20-1 longshot to win the race.
