That's it for Mets closer Francisco Rodriguez: K-Rod tore a ligament in his right thumb last week at Citi Field when he allegedly hit the grandfather of his children. The pitcher returned to the field following a two-day suspension, but doctors have ordered him to undergo surgery, which may effectively put him out for the rest of the season. Rodriguez has been charged with third-degree assault and second-degree harassment. While his agent refused to comment on whether his client's injury is a direct result of last week's fracas, a team official told ESPN: "You can make the assumption that the injury resulted from the incident last week." Even worse: His team management is seeing whether they can void his contract as a result.
