Justify won the Preakness Stakes on Saturday at Pimlico Race Course in Baltimore.
The horse's victory in the fog and mud brought him closer in his quest to score the coveted Triple Crown, after winning the Kentucky Derby earlier this month.
Preakness is the "Middle Jewel in the legendary Triple Crown where the best horses and jockeys compete for a chance at the ultimate prize in thoroughbred racing," according to the race website. "If it doesn't happen here, it doesn't happen."
Justify, who was favored to win the race, and his jockey, Mike Smith, defeated seven other horses.
"He got a little tired," Smith said. "This is his hardest race that he's had."
Competitors Bravazo and Tenfold finished in second and third place, respectively, in the 1 3/16-mile race.
Justify's record now stands at 5-0 as he looks on to the Belmont Stakes in New York on June 9. If the horse wins there, it would be trainer Bob Baffert's second Triple Crown victory in four years.
"I'm so happy that we got it done," Baffert said. "I've never had one run that fast here."
It's also the sixth time in six tries that Baffert has won the Preakness after winning the Kentucky Derby. His seven Preakness victories matches the record set by R.W. Walden in the 1800s.
The weather in Baltimore on Saturday was similar to the rainy, muddy conditions Justify faced during the Kentucky Derby.
