BALTIMORE — The buzz at Pimlico is all about Big Brown and what he can do for you today as the 1-2 favorite in the $1 million Preakness Stakes.

Can he position himself for a possible Triple Crown by adding the Preakness to the Kentucky Derby that he won two weeks ago by 4 3/4 lengths?

It might all come down to the start when 12 horses (Behindatthebar has scratched) break from the gate for this 1 3/16-mile race.

That's the opinion of his trainer, Rick Dutrow, and of others whose horses will try to beat the undefeated and seemingly invincible Big Brown.

"It's all about the break," said Dutrow at Pimlico on Friday. He cited the best example from recent history: War Emblem, a horse used to running only on the lead, losing the 2002 Belmont Stakes after breaking nearly last.

"When you come out of the gate and the horse stumbles pretty bad, right away horses are in front of them ... and you've got a lot of things that you have to deal with," Dutrow said.

"If it happens ... if he stumbles bad ... the break in my opinion is the only issue we have to worry about," Dutrow said.

Byrd is flying high in AT&T Classic

DULUTH, Ga. (AP) — Jonathan Byrd took advantage of soft fairways and receptive greens at TPC Sugarloaf on Friday, shooting his second straight 6-under 66 to take a three-stroke lead in the AT&T Classic.

Byrd, seeking his fourth PGA Tour victory, shared the lead with Kenny Perry, Ryan Palmer and two others when the second round began.

The course was drenched with over an inch of rain Thursday and, though no precipitation fell in the second round, overcast conditions kept the sun from drying off the fairways and greens and making the course play faster.

Kenny Perry and Ryan Palmer shot 69s to drop into a tie for second. Parker McLachlin, another first-round leader, shot a 70 to drop into a three-way tie for fourth with Charles Howell III (69) and David Toms (69) at 8 under.

Defending champion Zach Johnson (70) and Sugarloaf resident Stewart Cink (71) were seven strokes back at 5 under.
