In a somewhat surprising move, the Chicago White Sox signed 30-year old catcher Welington Castillo to a two-year deal with a club option, according to The Athletic's Ken Rosenthal. What makes this move surprising is it appeared that Kevan Smith and Omar Narvaez would get time to grow up during the rebuild. Instead, Rick Hahn adds a veteran catcher who can handle his own defensively and provide an offensive boost in the lineup.
Plus, there is an option that Castillo could be with the White Sox when they being their transition from rebuilder to contender.
