The position of catcher for the 2017 Diamondbacks had been in a state of flux since the somewhat surprising decision by the new front-office to non-tender Welington Castillo, rather than pay him $6 million or so in arbitration. The team did sign veteran Jeff Mathis, a wizard of pitch-framing, but it seemed dubious that he would be able to play everyday, having averaged only 46 games over the past three seasons. There had been a suggestion that the team might be looking at Matt Wieters, but the team appears to have gone in another free-agent direction.
