Travis d’Arnaud’s power has disappeared this season, resulting in a mere .624 OPS. Even with his struggles, d’Arnaud has, at the very least, earned a chance to split time with Rivera in the playoffs.
d’Arnaud’s diminished bat still provides more than Kevin Plawecki, who has a .546 OPS in 127 MLB at-bats. Plawecki’s defense isn’t good enough to outweigh his poor bat, thus his omission from the roster.
Rene Rivera has secured his spot on the roster as the personal catcher for Noah Syndergaard. Rivera’s defense is superior to d’Arnaud and Plawecki, thus he has become the antidote to teams running all over Syndergaard.
Rivera has also taken on a similar role with young pitchers like Seth Lugo and Robert Gsellman, who may wind up being vital to a postseason run.
