NEW YORK -- Jorge Posada spent his Friday morning at home, testing his injured right knee by squatting in street clothes at his house.
If Posada plays in Friday evening's game against the White Sox, however, he will do so not in a squat but a batter's stance. Though Posada called his swollen right knee "good" and said he could have started the game at catcher, the Yankees decided to withhold him from the starting lineup for a second straight day.
"The swelling's got to go down, but it will be all right," Posada said. "I could have played today, but they decided to give me another day."
Yankees manager Joe Girardi said Posada was available to pinch-hit if needed.
"He is going in the right direction," Girardi said. "He does still have some swelling. I think we're looking at [Saturday] or the next day, possibly. I'm going to see how he does."
After plunking Posada on the right knee with a pitch in Wednesday's game -- but before Girardi made some critical comments regarding his control -- Orioles starter Jeremy Guthrie apologized for the incident.
Posada said he did not believe the gesture was necessary.
"I read the paper," Posada said. "I didn't see anything wrong with what he did. I didn't think he needed to say what he said, but it's good that he said that."
