New York Mets closer Francisco Rodriguez, who was arrested last week after an altercation with his girlfriend’s father, will likely miss the rest of the season with a torn ligament in his thumb. Rodriguez must undergo surgery on the thumb and is expected to miss up to eight weeks. While team medical staff hasn’t confirmed the source of the injury, several media outlets have reported it occurred last Wednesday, when Rodriguez allegedly hit his girlfriend’s father outside the Mets’ clubhouse following a loss to the Colorado Rockies. Rodriguez was arrested for third-degree assault, and released a day later. The Mets issued him a two-game unpaid suspension before he appeared in Saturday’s game. In 53 appearances this year, the man known as “K-Rod” has a 4-2 record, 25 saves and a 2.20 ERA.
