Between the time the Grey Goose Breeders’ Cup Juvenile winner crosses the finish line and enters the winner’s circle on Saturday at Santa Anita Park, the conversation will have shifted from having won the race to whether he can win THE race — the Kentucky Derby.

In addition to fueling dreams of roses and the First Saturday in May, the Breeders’ Cup Juvenile also offers as its prize nearly $1.2-million to the winner and a likely Eclipse Award as champion two-year-old male.

The top two contenders for that honor are Champagne Stakes winner Shanghai Bobby and FrontRunner Stakes winner Power Broker, and in what is becoming a familiar storyline in Thoroughbred racing, the former is from the East Coast while the latter is on the West Coast.

“It’s [Shanghai Bobby’s] first time going two turns,” said Pletcher’s Santa Anita-based assistant, Mike McCarthy. “It’s going to be very exciting. Obviously, there’s a championship on the line. His [undefeated] record speaks for itself.”

Adding to the intrigue is that Shanghai Bobby ships west undefeated for trainer Todd Pletcher, who won this race in 2010 with undefeated champion Uncle Mo while Racing Hall of Fame trainer Bob Baffert conditions Power Broker. Both horses won their prep for this in impressive fashion, and although Shanghai Bobby is the slight 2-to-1 favorite on the morning line, either could end up favored when the gates open.

If racing fans follow conventional sports wagering conventions and give extra credit for “home-field advantage” (worth a couple-few points in football) then Power Broker will certainly be favored, and why not? West Coast horses won in 2003 (Action This Day) and 2008 (Midshipman), and Baffert trained that 2008 winner as well as 2009 runner-up Lookin At Lucky.

Both Shanghai Bobby and Power Broker race near the lead but not necessarily on it. Power Broker’s stablemate, Title Contender, drew the rail, and is likely to set the pace from that post position. Following a third-place finish in his career debut on Polytrack at Del Mar, Title Contender broke his maiden at Santa Anita in gate-to-wire fashion.

“Power Broker is doing good,” Baffert said. “A lot of what happens with him and all these horses is how the track is playing. So far at this meet it has been fair. It has some bounce to it. I’ve had horses win in front and win coming from far back.”

If the winner does come from far back, it could be either Dynamic Sky or Capo Bastone — two horses who closed strongly in their preps for this when Dynamic Sky was second to Joha in the Dixiana Breeders’ Futurity and Capo Bastone was third to Power Broker in the Front Runner.

Other contenders include Fortify, who has attracted his share of interest because he does not race on Lasix, the medication that helps prevent bleeding that is legal on race day in North America but not in most other places throughout the world. The Breeders’ Cup has banned its use in two-year-old races at this year’s event with a look to a complete ban planned for the 2013 event.

“We’ve go to come up with a way to beat Shanghai Bobby,” trainer Kiaran McLaughlin said of Fortify, who finished second behind that one in the Hopeful and third in the Champagne.
