NEW YORK (AP) — Sir Winston provided a perfect finish to a crazy Triple Crown.

After a disqualification in the Kentucky Derby and a runaway horse in the Preakness, of course the Belmont Stakes goes to a 10-1 long shot.

Sir Winston captured the US$1.5-million race Saturday, holding off favoured Tacitus by a length.

The win gave trainer Mark Casse the final two jewels in the showcase for three-year-old thoroughbreds. He won the Preakness with War of Will, who was expected to battle Tacitus in the 1 ½ mile Belmont.

Instead, Casse’s other’s colt took the lead after a ground-saving ride by Joel Rosario.

It wasn’t really a shock to Casse.

“I said all week he was doing really well,” Casse said. “He had a race over the track. What can I say? It’s just exciting.”

Sir Winston, who was making his Triple Crown debut, finished second in the Peter Pan Stakes, the traditional prep for the Belmont.

Rosario rode him for the first time in that race, and the two put on a show Saturday in front of a crowd of 56,217, earning US$800,000 for owner Tracy Farmer.

Long shot Joevia finished third and Tax was fourth.

The Triple Crown grind caught up to Preakness winner War of Will, who ran in all three races. He finished ninth in the 10-horse field.

“I could see where War of Will was struggling a little bit,” Casse said. “He looked like maybe he was a little flat today.”

The Belmont capped an entertaining Triple Crown highlighted by the disqualification of Maximum Security in the Kentucky Derby. It sparked interest in thoroughbred racing, despite no possibility of the third Triple Crown winner in five years, coming on the heels of Justify last year and American Pharoah in 2015.

It was all positive. There were no tragedies on the track. No horses died.

The Belmont was a jockey’s race and Rosario was the right rider on a horse full of run.

Breaking from the number seven post, Rosario guided the chestnut colt to the rail for an energy-saving trip. Sir Winston was eighth for the first half mile and then started to rally on the final turn.

Up front 21-1 long shot Joevia continued to set the pace, with Tax closely tracking. In the stretch, Rosario angled Sir Winston — named for Winston Churchill — off the rail and slightly bothered stablemate War of Will.

This time, there was no inquiry or objection. Sir Winston surged to the lead with an eighth of a mile to go and held off a late run from Tacitus, who had an extremely wide trip under jockey Jose Ortiz.

The second-place finish denied trainer Bill Mott two-thirds of the Triple Crown. His Country House was awarded first place in the Kentucky Derby.

Sir Winston paid US$22.40, US$8.80, and US$6.10. Tacitus returned US$3.90 and US$3.20 as the 9-5 favourite. Joevia hung on for third, paying US$8.70.

After Tax, Master Fencer was fifth followed by Spinoff, Everfast, Intrepid Heart, War of Will and Bourbon War. The winning time was 2:28.30 on the fast track under sunny skies.

The win was the third in 10 starts for the slow-developing Sir Winston. Casse always believed in the horse, despite early struggles.

“We’re very proud of him,” the 58-year-old trainer said. “He’s kind of what our operation represents — we develop horses. The first two times he ran, he got beat 10 or 20 lengths. I can remember having a conversation with Mr Farmer up at Saratoga and I said ‘Don’t give up on him.’”

The feeling paid off — big time.

This unpredictable Triple Crown season started with a wild result in the Kentucky Derby. Maximum Security crossed the finishing line first and became the first apparent winner to be disqualified, taken down for interfering with War of Will in the stretch. Country House was elevated to first, giving Mott his first Derby win and becoming the second-longest shot (65-1) to win the Derby.

War of Will came back two weeks later to win the Preakness, but his impressive performance was overshadowed when a rival threw his jockey and ran around the track as the race continued.

There were three major races on the Belmont undercard.

Mitole extended his winning streak to seven with a gutsy victory in the US$1.2-million Metropolitan Handicap. Pressing the pacesetting Coal Front every step, Mitole put away that rival in midstretch and held off the late challenge by 8/5 favourite McKinzie to prevail by three quarters of a length. Thunder Snow, the richest active thoroughbred with over US$16 million in earnings, was third.

Trainer Chad Brown dominated the Manhattan Stakes as his horses swept the first three spots in the US$1-million Manhattan turf race. Bricks and Mortar rallied to extend his winning streak to five, besting stablemate Robert Bruce by 1½ lengths. Raging Bull was third.

Guarana, also trained by Brown, beat Kentucky Oaks winner Serengeti Empress by six lengths in the US$700,000 Acorn for three-year-old fillies.
