LOUISVILLE, Ky. (AP) — Street Sense showed plenty of that, smartly picking his way through traffic while rallying from next-to-last in a 20-horse field to win the Kentucky Derby.

With a rip-roaring dash to the finish line at Churchill Downs, Street Sense put a couple of guys in the winner’s circle late in their careers. And in beating Hard Spun by 2 1-4 lengths, the colt broke two Derby jinxes under jockey Calvin Borel, who was winless in four tries until now.

“I can’t believe it, I can’t believe it. This is the toughest race in the world to win,” trainer Carl Nafzger said.

Street Sense became the first Breeders’ Cup Juvenile winner to return in the spring and win on the first Saturday in May, snapping an 0-for-23 skid. He did so on the same track where he won the Juvenile by 10 lengths six months ago. He was also the first 2-year-old champion to win the Derby since Spectacular Bid in 1979.

The dark bay colt, sent off as the 9-2 favorite on his hometown track, ran 1 1/4 miles in 2:02.17 and paid $11.80, $6.40 and $4.60 as the highest-priced winning favorite in Derby history. Smarty Jones paid $10.20 to win in 2004.

Hard Spun returned $9.80 and $7, while Curlin was another 5 3/4 lengths back in third and paid $5.60 to show.

While it was Nafzger’s second win in three tries, trainer Todd Pletcher, who had a record-tying five horses, was skunked again. He is now 0-for-19 in the Derby.

“I am disappointed that the horses didn’t run better,” Pletcher said. “It isn’t the end of the world if you don’t win the Kentucky Derby. I’m not going to go home tonight and cry. That’s just not the way.”

Queen Elizabeth II and her husband, Prince Philip, were among the 156,635 racing fans on hand, the third-largest crowd in the Derby’s 133 years. They watched from the fourth-floor clubhouse balcony overlooking the finish line. With the sun finally emerging before post time, they had a picturesque view of the famous Twin Spires.

Asked what it was like to win in front of royalty, Borel said jokingly, “It meant everything in the world.”

The 65-year-old Nafzger, who is nearly retired, wasn’t as emotional as he was in 1990, when Unbridled won for 92-year-old Frances Genter. Because of her faltering eyesight, Nafzger called the race in her ear so she could follow her colt to the finish line.

Then he gave her a big kiss when Unbridled crossed the finish line.

This time, Nafzger’s words to 83-year-old owner James Tafel were few and to the point.

“Mr. Tafel, we’re clear, we’re clear. It’s up to him now,” Nafzger said.

Street Sense left from the same No. 7 post as Unbridled 17 years ago. The moment Street Sense crossed the finish line Nafzger wrapped his arm around Tafel, shook his hand and pumped his left fist.

By the time the two made their way to the crowded winner’s circle, the white-haired Tafel was beaming.

“This is the aspiration of anybody and everybody in the horse business. It’s just overwhelming,” said Tafel, retired from a technical publishing company and living in Boynton Beach, Fla.
