Hampered by a stiff back, the 34-year-old hasn't appeared in a game since Sept. 3 and hasn't started since Aug. 8.
Bloomquist is starting to improve, however, and the D-backs might begin pushing him into more serious workouts to test the injury.
"He's been feeling much better," D-backs manager Kirk Gibson said. "We're looking at starting to give him some more intensive activity."
Gibson added that on a pain scale from 1-to-10, Bloomquist put himself at a 1.
On the season, the infielder is batting a career-high .302.
It is possible Bloomquist won't need much rehabbing before he gets back on the field. The last time he pinch-hit for the D-backs on Sept. 3, he simply was feeling good before the game.
In his one at-bat, Bloomquist collected a hit, an RBI and scored a run.
