New York Mets catcher Francisco Alvarez has a torn ligament in his left thumb and will need surgery, manager Carlos Mendoza said Saturday after a 6-4 win against the Los Angeles Dodgers.

Alvarez was placed on the 15-day injured list before the game with a sprained left thumb suffered while running the bases the night before in a 9-4 victory against the Dodgers. An MRI was performed late Friday night.
