Center fielder Chris Duffy likely will be on the disabled list by today.

Duffy sustained a "significantly" sprained left ankle, according to manager Jim Tracy, while turning to chase down Alfredo Amezaga's gift triple in the eighth inning in Miami Thursday.

Duffy had X-rays taken Thursday and yesterday he had an MRI to determine if there was damage to ligaments in his ankle. The MRI showed no ligament damage.

"He's not very mobile," Tracy said.

With Duffy on the DL, center field could be manned by Rajai Davis and Nate McLouth.

Nutting tries to defuse protest
The Pirates emphasized yesterday that tonight's Bob Walk bobblehead promotion and planned fan walkout protest after the third inning is not a sellout. The advance for the game is in the mid-20,000 range, the Pirates said.

Bob Nutting, the Pirates' principal owner, yesterday issued a statement in which he obviously was trying to blunt the impact of the fan protest.

"I appreciate the passion of all of our fans and their frustrations with the team's performance," Nutting said in the statement. "Frankly, we all share in this frustration. Everyone throughout the organization understands the expectation and need to perform.

"I have not lost faith in the team or our core group of young players. There is still a lot of baseball to be played. Our focus as an organization remains on winning games.

"Finally, it is important to point out the immense appreciation I have for the continued loyalty and support from all of our fans."

Walk unfazed by protest
Is Walk a bit miffed that his bobblehead promotion seems to be getting overshadowed by the fan protest?

"I'm not irritated by it," Walk said. "You know me -- I'm kind of humbled and embarrassed by having the bobblehead thing. I feel uncomfortable enough. I'm not going to be bothered by anything. Whatever happens, happens."

Wilson and donuts
Pirates shortstop Jack Wilson was the star of a news conference yesterday.

He was picked by Franco Harris and Pittsburgh-based R Super Foods to have his picture adorn packages of Super Donuts and Super Buns.

"Having a donut box with your face on it is awesome," Wilson said.

Harris said Wilson, who joins Penn State football coach Joe Paterno and Steelers wide receiver Hines Ward as donut honorees, was selected because of his community involvement.

Harris said this recognition will expand in the fall to include athletes in Cleveland, Cincinnati, Chicago and Philadelphia.

"It's definitely an honor for me," Wilson said. "It's always been fun for me to do charity things in the community."

A portion of the sales of Wilson pastries will be donated to a charity of Wilson's choice.

Bay and Wilson's donuts
Jason Bay's reaction to Wilson's honor? "I guess that's where we are as far as media coverage right now. It's something we can all bust his chops about. The only thing that will save him [from a lot of kidding] is if the donuts taste good."

Quick exits
Last night was Fireworks Night. That meant most of the players hustled off the field and left the stadium quickly to try to avoid traffic. Just how do they accomplish that?

"Well, hopefully you've just shaken hands on the field [following a victory]," Wilson said. "Then, you run up from the dugout [to the clubhouse]. A pitcher has the job of turning on the showers and warming them up -- it's a collective effort. Then you soap up, shower, wash your hair real quick, dry off, get dressed and bolt."

No Zach attacks
Zach Duke's pitching line was not good again Thursday, which created more media discussion about whether the left-hander should be sent to Class AAA Indianapolis.

"We're not going to sit here and talk about should he be in the big leagues or should he be in the minor leagues," Tracy said. "We're not going to discuss that."

Tracy's son bags win
Tracy's son, Brian, got his first pro victory Wednesday night when State College beat Batavia, 10-6. Brian Tracy, the Pirates' 20th-round pick three weeks ago, pitched three hitless innings, allowing no runs.
