Welington Castillo – Washington Nationals

Yadier Molina and Buster Posey are the standard bearers among National League catchers, but the Arizona Diamondbacks’ Wellington Castillo is making a compelling case to be named to the all-star team through his first 32 games in 2016.
Castillo is slashing .290/.328/.508, his seven home runs the most among major league backstops. His slugging, wOBA, and wRC+ all rank in the top four, and he has been very solid defensively, even coming in ahead of Molina in FanGraphs’ defensive rating.

The offensive breakout should maybe not be surprising, as Castillo hit well after being dealt to the Dbacks last summer. If he continues at this pace while catching the likes of Zach Greinke, he could be one of the NL’s signal callers in San Diego come July.
