The Arizona Diamondbacks are expected to be without A.J. Pollock for four to eight weeks with a broken left thumb.
Pollock was injured diving unsuccessfully for a line drive that turned into an inside-the-park home run on Monday night against the Milwaukee Brewers.
He has an avulsion fracture, which occurs where a tendon or ligament attaches to the bone.
"It's tough to lose anybody," Mike Hazen said, "but A.J., the way he was playing, it's a pretty big blow. But nobody's going to feel sorry for us. We've got to pick up and move on."
Pollock will be a free agent after the season.
