BALTIMORE -- First baseman Mark Teixeira was placed on the 15-day disabled list on Saturday with a right knee articular cartilage tear. The Yankees called up infielder Chris Parmelee from Triple-A Scranton/Wilkes-Barre and transferred Dustin Ackley, who is out for the season with a shoulder injury, to the 60-day DL.
Teixeira left Friday's 6-5 loss to the Orioles in the third inning with discomfort in his right knee. Manager Joe Girardi said that while Teixeira has been dealing with pain in his right knee this season, Friday was the first time that it locked up.
