The Mets made a a few trades before the trade deadline this year, the first of which included Kelly Johnson, a player who is no stranger to getting traded. Drafted by the Braves back in 2000, Johnson was drafted by and played for the Braves and had played for six different teams in between before rejoining the Braves to start the 2015 season.
At the time, Johnson was having one of his better recent seasons. He had hit .275/.321/.451 with a 111 wRC+ for the Braves before the Mets acquired him. Given the Mets' roster, that sort of production represented a significant upgrade.
Johnson didn't quite maintain that level of hitting, but he played decently in his time with the Mets, with a .250/.304/.414 line, five home runs, and a 100 wRC+ in 138 plate appearances through the rest of the regular season. With the Mets, Johnson spent the grand majority of his time playing second base, but he appeared in both corner outfield spots and at first base, third base, and—for one experimental game late in the season—at shortstop. He didn't play much in the playoffs, but he hit just .111/.200/.111 in his 10 trips to the plate.
Like several of his teammates with the Mets, Johnson is now a free agent. A left-handed hitter, he could make sense for the Mets in 2016 as a backup infielder and corner outfielder, pending any other moves the team makes this winter.
