The Diamondbacks claimed catcher Craig Tatum off of waivers from the Astros, ESPN.com's Keith Law tweets. The Astros designated Tatum for assignment last week to create roster space for Jack Cust. The 28-year-old backstop will provide the Diamondbacks with another option behind Miguel Montero and Henry Blanco.
The Astros had claimed Tatum from the Orioles in October. He has three partial seasons of catching experience at the Major League level and isn't yet eligible for arbitration. He has a .223/.291/.264 line in 299 MLB plate appearances and has stopped 21% of stolen base attempts against him. In eight seasons as a minor leaguer, the 2004 third round pick has a .249/.316/.377 batting line and has stopped 35% of stolen base attempts.
The Diamondbacks, who have confirmed the move, note that their 40-man roster is full.
