Chase Headley (thumb) took soft ground balls Monday. The injured third baseman has also been lifting weights and taking one-handed swings in a batting cage. He has a checkup with doctors next Monday and is hoping to be cleared for higher-intensity workouts. "There are a lot of things I can do," Headley said Monday morning. "When I'm cleared for baseball activity, I want to hit the ground running." He's expected be ready in early May.
