Baseball’s free-agent market has moved more slowly than the LIE at rush hour. But the Mets have been keeping tabs on Jay Bruce, a familiar face who would fill the need for a power bat capable of playing rightfield and first base.

According to a source, the sides have expressed mutual interest in a reunion.

Eric Hosmer, Carlos Santana and Adam Lind have been among the first basemen linked to the Mets. But Bruce provides versatility and familiarity, having started last season with the Mets before his July trade to the Indians.

Bruce, 30, has been primarily a rightfielder, and he’d give the Mets a needed presence there in case Michael Conforto’s recovery from shoulder surgery hits a snag. Bruce also has played first base, where the Mets are targeting upgrades over Dominic Smith.
