Bloomquist could return for finale vs. Padres

PHOENIX -- Designating Jason Kubel for assignment Tuesday opened up the possibility of the D-backs activating veteran infielder Willie Bloomquist from the disabled list as soon as Wednesday. David Holmberg took the opened roster position Tuesday to make a spot start, but the club will not need a sixth starting pitcher come Wednesday.

Depending on how much the D-backs used their bullpen Tuesday, the club would most likely make another roster move for a position player Wednesday. Bloomquist, on the shelf since June 28 with a broken left hand, was with Triple-A Reno on a rehab assignment.

"Kind of right now, we're going to see how we get through this game tonight and see what our needs are," D-backs manager Kirk Gibson said before Tuesday's game. "If we have to go get a pitcher, we'll probably hold [Bloomquist] off and have him play another game down there."

Bloomquist hit 6-for-12 in four games with the Arizona League (Rookie) D-backs last week and went 1-for-3 on Monday in his first game with Reno.
