Posada, it turns out, was fine.
After staying out of the starting lineup for two straight games with a swollen right knee, Posada returned against the White Sox on Saturday, batting sixth and catching.
Posada, who was hit by a Jeremy Guthrie pitch in Wednesday's game against the Orioles, struck out in a pinch-hit at-bat Friday, after telling Girardi that he could have started the game. Girardi kept him out of the lineup as a precaution.
"He still had some swelling, and that's somewhat of a concern of mine," Girardi said.
Posada entered the game batting .310 with five home runs in 58 at-bats. He went 0-for-4 in the 7-6 loss.
