Rangers reliever Mark Lowe threw batting practice this week and reiterated that he believes his strained hamstring is fully healed. Lowe suffered the injury on Sept. 21. "Of course, I want to contribute," he said. The teams don't have to submit World Series rosters until 10 a.m. Wednesday. If Lowe is given a spot, it probably would be at the expense of Yoshi Tateyama or Koji Uehara.
