Nieuwenhuis (hamstring) should be ready for a return to action by early next week, Greg Johns of MLB.com reports.
The veteran outfielder last saw game action last Thursday, but he appears to be inching closer towards a return. Nieuwenhuis is competing for a reserve outfielder role this spring, although his sluggish start (1-for-10 with an RBI) and subsequent injury have naturally set his job quest back.
