The Texas Rangers have placed starting 3B Hank Blalock on the 15-day disabled list with inflammation in his right shoulder. Blalock has played in 31 games for the Rangers this season and he is 33 for 121 (.273 avg, .769 OPS) with 13 runs scored, 4 homers and 15 RBIs. Ramon Vazquez will likely start at 3B while Blalock is out. He has played in 72 games for the Rangers this season and he is 68 for 220 (.309 avg, .848 OPS) with 38 runs scored, 5 homers and 31 RBIs. 27-year old righty swinging infielder Ryan Roberts has been brought up from AAA to replace Blalock on the active roster. Roberts has played in 102 games in AAA ball this season and he is 97 for 341 (.284 avg, .838 OPS) with 59 runs scored, 8 homers, 50 RBIs and 11 stolen bases. Roberts won’t likely get much playing time unless another infielder goes down to injury for the Rangers.
