The backup-turned-starting Mets catcher took a ball off his right wrist during Friday’s game, arrived at Citi Field with a painful contusion Saturday and, after trying to ramp up pregame, ended up being a late scratch.

Just one day after manager Carlos Mendoza provided a positive update on regular starting catcher Francisco Alvarez, who is progressing back from a fractured hamate bone in his left hand, the Mets suddenly scratched the catcher starting in his place.

NEW YORK — Bad weather won’t be the only obstacle the Mets will have to overcome against the Toronto Blue Jays on Saturday. About 20 minutes before first pitch, the club announced that catcher Luis Torrens was scratched from the lineup with a right forearm contusion. Hayden Senger will make his Citi Field debut instead.
