Jason Heyward's Arizona Fall League season has ended after just four games due to a lower back strain. Heyward, 20, was examined Tuesday by Dr. Marvin Royster, who diagnosed back inflammation that was radiating to Heyward's gluteus. Heyward, recently named Baseball America's Minor League Player of the Year, will be invited to his second major league spring training in February and this time the Braves say he will compete for a major league job.
