Ken Griffey Jr. remained out of the Cincinnati Reds' lineup for a second day Friday because of pleurisy, an inflammation in the lining of a cavity surrounding the lungs.
Griffey was held out of Thursday's game in St. Louis because of soreness in his chest. A chest X-ray on Friday revealed the problem, which is not expected to be long-lasting. He pinch-hit in the seventh inning against Pittsburgh, drawing a walk before being replaced by a pinch-runner.
Griffey recently sat out four games because of diverticulitis, a colon condition that was initially diagnosed six months ago.
Players' union head Donald Fehr doesn't plan to be at the ballpark if and when Barry Bonds sets the career home run record.
"I won't follow him around, but I generally don't go to games during the season, so that's nothing new for me," Fehr said during a meeting with the Associated Press Sports Editors.
