Yankees third baseman Alex Rodriguez has a slight meniscus tear in his right knee and could miss a month of action if he opts to undergo surgery. Rodriguez, who had an MRI Friday, will not play Saturday afternoon against the Rays. New York manager Joe Girardi said that Rodriguez could opt to play through the injury and have surgery at the end of the season. Rodriguez, 35, is hitting .295 with 13 home runs and 52 RBIs this season.
