My shoulder is hurting after hitting baseballs today. it is a sharp pain on the front of my shoulder. could i have pulled something?

Possible Strain: If you haven't had this pain very long and haven't suffered any significant injury, it may be a strain of your ac joint (where the collarbone meets the shoulder blade). Often avoiding activities that cause the pain for a while will result in improvement. For persistent pain: http://www.Theshouldercenter.Com/shoulder-specialist.Htm.
