MINNEAPOLIS -- Jorge Posada caught six innings in an extended spring game on Monday, and he remains on track to rejoin the Yankees later this week.
Posada went 1-for-3 in the contest against Phillies Minor Leaguers in Tampa, Fla., making two throws to the bases -- the second game that he was permitted to do so. Posada has been sidelined since April 27 with a sore right shoulder.
"You keep working on things and try to throw," Posada told the Associated Press. "I threw the ball behind the runner and felt good about it."
Yankees manager Joe Girardi said that he had not heard an updated report on Posada before New York's game against Minnesota, but he expected that Posada's previous timetable would hold.
It is possible that Posada could be added to the Yankees' roster on Wednesday as a potential pinch-hitter, with the plan to have him catch New York's game against Toronto on Thursday.
Posada is 9-for-25 with six walks in five extended spring games. He's expected to catch one more extended spring game on Tuesday, and he will be evaluated on Wednesday.
Additionally, the Yankees placed right-hander Jeff Karstens on the seven-day Minor League disabled list with a sore right groin.
Karstens, who was pitching for Triple-A Scranton/Wilkes-Barre, originally injured the groin pitching in his final Grapefruit League appearance on March 27.
He could have merited consideration to be promoted as a long reliever on Tuesday, when the Yankees plan to make a roster move, but it appears like right-hander Dan Giese will be promoted from Scranton/Wilkes-Barre instead.
