All season, the Mets had a significant problem at the catcher position. Travis d'Arnaud and Kevin Plawecki were each batting under .240 with an OPS under .700 at the end of August and minimal history of success to look back on, particularly in Plawecki's case. But both have had a surge of production that may help simplify an issue for a team facing a very complicated offseason.
On September 1, d'Arnaud was sitting on a .232/.281/.394 slash line over 306 plate appearancesm -- a deeply disappointing season in which he finally seemed to be capable of staying healthy for a long stretch. Since the beginning of the month, though, he has been on fire, batting .315/.367/.741 with six home runs in 60 plate appearances, while striking out only five times.
It hasn't all been against September call-ups either -- five of his six home runs came against established major leaguers, and his OPS is seventh-best in baseball for the month. D'Arnaud's season line is still below major league average overall, but better than the average catcher, particularly in regards to power. He's not out of the woods yet, but this explosion could not have come at a better time.
