NEW YORK — Justify defied all the odds on his way to achieving horse racing immortality.
The late bloomer won the Belmont Stakes by 1¾ lengths Saturday, giving the sport its 13th Triple Crown champion. American Pharoah ended a 37-year drought in 2015 and now, just three years later, racing is celebrating another sweep of the Kentucky Derby, Preakness, and Belmont.
Justify began his racing career Feb. 18, a scant 77 days before the Derby. He won his first three races by a combined 19 lengths, making trainer Bob Baffert a believer.
The big chestnut colt with the appetite to match burst onto the national scene with a 2½-length victory on a sloppy track in the Kentucky Derby. Two weeks later, he survived a challenge in the fog-shrouded Preakness, winning by a half-length, again in the slop to set up a Triple Crown try.
‘‘The raw talent is there,’’ Baffert said. ‘‘He just came on there and broke every curse there was. It was meant to be.’’
On a cloudy 80-degree day at Belmont Park, Justify proved a cool customer.
He didn’t flinch when greeted by 90,327 roaring fans as he walked onto the track. He stood so quietly in the starting gate that jockey Mike Smith wondered if he'd respond when it sprang open.
Did he ever.
Justify led all the way in achieving one of the sports world’s toughest feats 45 years to the day that Secretariat won the Belmont by a record 31 lengths.
‘‘I think he’s the greatest of all time,’’ Smith said. ‘‘I just won the Triple Crown, man. He’s my champion.’’
Justify, sent off as the 4-5 favorite, ran 1½ miles — the longest race of the series — in 2 minutes 28.18 seconds and paid $3.60, $3.50, and $2.80.
Gronkowski, named for and partly owned by New England Patriots tight end Rob Gronkowski, challenged on the home stretch and finished a strong second. He returned $13.80 and $7.
Hofburg paid $3.70 to show.
Justify accomplished a lot in a very short time.
At 6-0, he joins Seattle Slew in 1977 as the only two undefeated Triple Crown winners; he’s the first to sweep the series without racing at age 2; and he’s the only horse to beat nine rivals in the Belmont with a Triple try on the line. Slew also was a wire-to-wire Belmont winner.
Justify’s human handlers also made history.
Baffert became the second trainer to win the Triple Crown twice, having overseen American Pharoah. James ‘‘Sunny Jim’’ Fitzsimmons guided Gallant Fox in 1930 and Omaha in 1935.
‘‘It never gets old,’’ Baffert said. ‘‘American Pharoah, he'll always be my first love.’’
At 52, Smith became the oldest jockey to win the Triple Crown. He celebrated by grabbing white carnations from the winner’s blanket and tossing them in the air.
‘‘He just puts an old man out there to sit still, who stays out of the way and lets a good horse be a good horse,’’ Smith said, crediting Baffert for using him.
Smith and Justify took a curtain call before entering the winner’s circle. Back in New York where he dominated in the 1990s, Smith took Justify on a walk past the packed grandstand, soaking in the cheers and giving the crowd a closer look at racing’s newest hero.
Purchased for $500,000, Justify earned $800,000 for his Belmont win, giving him $3,798,000 in his brief career.

The powerful colt with the blaze running the length of his face showed no signs that the rigors of running a compressed schedule had gotten to him.
On a fast, dry track, Justify was just as good in his third race in five weeks at his third track.
‘‘This horse ran a tremendous race, he’s so gifted,’’ Smith said. ‘‘He’s sent from heaven. I tell you, it’s just amazing.’’
Baffert had fretted after Justify drew the No. 1 post, a spot he detests for his horses. But Smith turned it into an advantage, gunning Justify to the lead and defying any horse to challenge.
Restoring Hope, also trained by Baffert, ran interference for the champion while traveling second and deterring any threats by forcing them to go extremely wide. Nobody did.
Smith got the colt into a relaxed rhythm under a moderate pace heading into the backstretch, and he had an easy trip from there.
There were mild bids turning for home. Vino Rosso made the most serious move to get within a length but never threatened. Justify pulled away down the 1,097-yard stretch in front of screaming fans with only 24-1 shot Gronkowski picking off a half-dozen rivals in taking up the chase down the lane.
‘‘My thought turning for home was that he had a shot to get him if Justify was vulnerable at mile and a half,’’ said Chad Brown, who trains Gronkowski. ‘‘I thought maybe, because I could see Gronkowski flying, but he just couldn’t get to that horse.’’
