The Mets have added minor league catcher Mike Nickeas to the major-league roster.

The third September call-up will join the Mets here on Thursday. His name is Mike Nickeas. He is a 27-year-old catcher who began the year in Double A.

To make room for Nickeas on the 40-man roster, the team transferred John Maine to the 60-day disabled list. Maine underwent season-ending shoulder surgery in July.

He is likely to be non-tendered at season’s end.

Nickeas will provide some insurance for starter Josh Thole and backup Henry Blanco. He was batting .279 with Binghamton and Buffalo this season.
