The Arizona Diamondbacks signed Caleb Joseph to a major league contract, reports the Athletic’s Zach Buchanan (via Twitter). Joseph becomes the fourth catcher with a guaranteed major league deal on the 40-man roster, joining Alex Avila, Carson Kelly and John Ryan Murphy.
Joseph was recently DFA’ed by the Baltimore Orioles, which in and of itself is not a good sign, but take it with a grain of salt as well: after all, the surest way to spot potential breakout candidates recently is has been to review lists of former Orioles.
