There has been a run on catchers lately. Last week it was Willson Contreras, the top free agent catcher on the market, signing a five-year, $87.5 million deal with the Cardinals. In the wake of that deal, other teams seeking catchers have made their moves this week, with the blockbuster three-way deal yesterday that sent All-Star Sean Murphy from the Athletics to the Braves, with catching prospect William Contreras (Willson’s brother) going from the Braves to the Brewers. Veteran Christian Vazquez, fresh off winning a title with the Astros, signed a three-year deal with the Twins.
