Plawecki is already at the Mets' spring complex to prepare for his role as the team's backup catcher and possibly see some time at first base. If Travis d'Arnaud is sideline again this season, Plawecki will once again step in as the Mets' starting backstop.
Those other positions are likely first base and left field, though d'Arnaud main work will come behind the plate. D'Arnaud has suffered a variety of injuries while catching, so moving him out from behind the plate has been discussed for a while. But his bat plays much better as a catcher than at another position.
Plawecki saw some time at first base in the minors, so playing the position won't be that foreign to him. It's unlikely he sees much time there, though he could possibly play against lefties when Lucas Duda sits and Wilmer Flores is deployed elsewhere in the infield.
According to Mark Bowman of MLB.com, Lalli will attend major league camp for spring training as a non-roster invitee, but the team intends to pair him with Ryan Lavarnway at Triple-A Gwinnett to start the season. The 32-year-old Lalli has made 40 plate appearances at the highest level, the last of which came back in 2013.
Federowicz isn't expected to be much more than organizational depth after four years of sub-Mendoza Line hitting in Los Angeles. He's likely to spend a few weeks with the top level, then open the season with Triple-A Iowa while Miguel Montero and David Ross occupy catcher in Chicago.
Grandal continues to work his way back from left shoulder surgery, and clearance to swing certainly represents a step in the right direction. Fortunately, the left shoulder issue really only impacts the backstop in the batter's box, as he throws with his right hand like nearly every other catcher. Barring something unforeseen, the 27-year-old should be on track to serve as the Dodgers' primary catcher once again in 2016 despite an underwhelming second half in 2015.
Mesoraco has reached the final stages of his recovery from season-ending hip surgery, which was undertaken on June 29 to repair a labrum and remove a spur. With hitting and some catching duties already behind him, his next test will likely be manning catcher in exhibitions. When healthy, he'll serve as the Reds' No. 1 backstop, from which he logged 100-plus games in both 2013 and 2014.
Monell had a solid year with Triple-A Las Vegas last year, batting .324 with seven home runs and 51 RBI. He also got a taste of the majors, but only managed to hit .167 in 52 plate appearances. With Travis d'Arnaud and Kevin Plawecki pretty well entrenched as the backstops at the major league level, Monell will likely serve as organizational depth once again. However, if he continues to destroy Triple-A pitching, the Mets may need to reevaluate him a bit.
Despite having 313 career big-league appearances to his name, the 32-year-old Kottaras will likely be no higher than fourth on San Francisco's organizational catching depth chart. At best, he'll compete with Trevor Brown for the No. 3 spot behind Buster Posey and Hector Sanchez.
Grandal was the centerpiece of a trade that brought sent Matt Kemp to the Padres in 2014. While his first half of the season was promising, he tanked in the second half to finish with just a .234/.353/.403 batting line. Despite the downfall, he should once again serve as the Dodgers' primary catcher in 2016.
