The D-Backs have claimed 28-year old righty swinging catcher Craig Tatum off waivers from the Houston Astros. Tatum played in 31 games for the Orioles last year and he was 17 for 87 (.195 avg, .475 OPS) with 7 runs scored, 0 homers, 7 RBIs and 1 stolen base. He has now played in 100 games in his first three years in the majors and he is 60 for 269 (.223 avg, .554 OPS) with 21 runs scored, 1 homer, 22 RBIs and 2 stolen bases. Tatum will likely start the 2012 season in AAA-ball unless Miguel Montero or Henry Blanco get injured in spring training.
