"The club and right-hander Daniel Hudson are believed to be close to agreeing to a new contract. Hudson, who was non-tendered last week, is believed to be seeking a deal that would include a 40-man roster spot. He is likely to miss most, if not all, of next season as he recovers from his second Tommy John elbow surgery. The club is expected to sign catcher Henry Blanco to a minor-league contract with an invite to big-league camp. Blanco will have a chance to compete for the backup catcher’s role. An announcement on the three players to be named later from the Diamondbacks’ two recent trades could come as soon as today. They’re expected to receive one player each from the Tampa Bay Rays, Los Angeles Angels and Chicago White Sox. None of the players the club was expecting to receive were selected in the Rule 5 draft, Towers said."
