LOS ANGELES -- The D-backs will activate Willie Bloomquist on Saturday when the rosters expand, but how active the shortstop will be remains to be seen.
Bloomquist was placed on the DL on Aug. 11 with a strained lower back. He recently completed a rehab assignment in the Arizona Rookie League but still has had some back stiffness when playing on consecutive days.
"I don't know if he's ready to play a full nine right yet, but I think he's able to pinch-hit, play a little bit," D-backs general manager Kevin Towers said. "We'll see how he feels on a day-to-day basis."
Bloomquist said that tests taken on the back earlier in the month showed a slight cartilage tear. Long term it is not expected to be an issue, but Bloomquist will need to give it an extended rest at some point, something he is not planning on doing right now.
"Some games it feels good, some games it stiffens up on me," Bloomquist said. "Some days it feels good, some days it doesn't."
The D-backs also plan on activating pitchers Josh Collmenter and Takashi Saito from the disabled list Saturday as well as adding infielder Cody Ransom to the roster. The organization also expects to add a pair of players from Triple-A Reno.
