Yankees catcher Francisco Cervelli has a broken left foot, the team said Friday, which could open the door for Jesus Montero to not only grab the back up catching job but to earn the full-time job. Cervelli's latest spring training injury (his third in four years) is expected to keep him in a walking boot for a minimum of four weeks. He is in the boot and on crutches. The fracture is above the toes and was caused by a foul ball off the arch Wednesday. Joe Girardi said Jorge Posada won't be put back in the mix. The manager said, "We still plan on having him being the DH.'' Though Girardi didn't hand the job as Russell Martin's backup to Montero, the Yankees' top position prospect has to be considered the favorite. Austin Romine, who hasn't played above Double-A, and Gustavo Molina, who has 23 games of big-league experience, are standing in the way of Montero becoming a big leaguer.
