PHILADELPHIA -- A prankster boarded up Greg Dobbs' locker with cardboard and yellow caution tape Friday at Citizens Bank Park because Dobbs had been out with flu-like symptoms. A note detailed visiting hours for Dobbs at the hospital, although he had never been hospitalized.

The cardboard and tape were removed Saturday because Dobbs had rejoined the team.

"I feel good," Dobbs said before Game 3 of the World Series. "I'm ready to go."

The flu has run through the Phillies' clubhouse. Right-hander Tyler Walker, who is not on the postseason roster, missed time recently because of an illness. He rejoined the team Friday. Closer Brad Lidge worked out Friday, but went home during the team's workout on the field because of an illness.

Lidge, who did not want to say much about his sickness, said he feels better and is available to pitch.

"A day of rest was good," Lidge said.

Pedro Martinez, who pitched Game 2 on Thursday, also said he felt sick in the days leading up to his start.
