Despite some scary moments in the stretch, Shanghai Bobby lived up to his 6-5 favoritism to take Saturday's $1,818,000 Breeders' Cup Juvenile by a head over He's Had Enough.

The Todd Pletcher trainee tracked the pacesetting Title Contender through fractions of :22 1/5 and :45 2/5 before asserting his class to take over entering the turn. Shanghai Bobby began looking around after opening up a clear lead heading into Santa Anita's stretch, but jockey Rosie Napravnik never panicked. She kept urging the dark bay colt on while saving ground along the rail until He's Had Enough pulled up to challenge on the outside.

That got the Harlan's Holiday colt's attention, and Shanghai Bobby dug in to secure the slim victory in a final time of 1:44 2/5 for 1 1/16 miles on the fast dirt.

"We were in a great spot. As a matter of fact, down the backside, I was having déjà vu of the (Grade 1) Kentucky Oaks (win aboard Believe You Can) and being in that golden spot," said Napravnik, who followed in Julie Krone's footsteps to become just the second female rider to win a Breeders' Cup race.

"That was our strategy, to be aggressive, the way the track was playing," Pletcher admitted. "We didn't want to get shuffled back.

"I kept going back on the Track Barron (at Belmont Park) in his second start. He went pretty fast early, and it looked like he was in trouble, but when horses engaged him, he fought on and found more. I was hoping he was going to be able to do that today. I was concerned about the fractions.

Shanghai Bobby moved his record to a perfect five-for-five with this win and essentially wrapped up champion two-year-old male honors while returning $4.60, $3.40 and $2.60 to his faithful backers.

"It's great to have an undefeated two-year-old and go all the way from April to November; it's pretty hard to do. It's a real feather in his cap," Pletcher added. "He's got everything you want. He's fast and he's courageous. He's handled everything we've thrown at him, from 4 1/2 furlongs to 1 1/16 miles. He just keeps coming."

He's Had Enough ran greenly in the stretch, drifting toward the grandstand before jockey Mario Gutierrez straightened him up and sent the Tapit colt up to Shanghai Bobby's throatlatch.

"To overcome all that trouble, he ran dynamite," said He's Had Enough's trainer, Doug O'Neill. "Right to the end, I was still thinking he was going to get there. He got beat by a nice horse."

Shanghai Bobby entered the Juvenile owning a five-length win in the Grade 1 Champagne at Saratoga and a 3 3/4-length score in Belmont Park's Grade 2 Hopeful. Prior to those two the juvenile broke his maiden at Aqueduct by four lengths and recorded a one-length victory in the Track Barron. With the winner's share from Saturday's race, the dark bay has now banked $1,687,000 in lifetime earnings.

"I think what impressed me a lot about Shanghai Bobby is the fact that he's so athletic, and he's so smart," said Napravnik, who's been aboard for all of the colt's races. "I wasn't really congratulating him on his smartness at the quarter-pole today but I was at the sixteenth-pole.

"He's a really cool horse, he has a personality. It makes my day every time Todd asks me to come and breeze him in the mornings, and not to mention in the afternoon he's just -- he's all heart, he's all race horse. He's exactly what every rider is looking for."

Bred in Kentucky by Stonehaven Steadings, Shanghai Bobby has more than earned back his initial purchase price of $105,000 as a Keeneland September yearling. It also didn't hurt that Coolmore principals Mrs. John Magnier, Michael Tabor and Derrick Smith purchased a 50 percent interest of the colt from owner Starlight Racing leading up to the Breeders' Cup.
