Braves rookie outfielder Jason Heyward has been placed on the 15-day disabled list with a deep bone bruise in his left thumb. The injury was revealed in an MRI exam on Monday. "We're doing the best thing, I believe," Heyward said Monday. "Right now is a good opportunity to get it done, get the rest done, get the strength back so I'll be able to come back the second half." Heyward has tried to play through the injury for about six weeks.
