My Achilles Tendon Is Sore During Every Baseball Game?

My achilles tendon is always sore during every baseball game. I am thinking its the cleats. I would bat, hit the ball and run and then after that running to 2nd base or so (about 200 feet) that spot would be sore (constant) and when I put pressure on it. Also, if I am standing around in my regular shoes and then I take a sudden sprint, the same spot is sore. I try to stretch the calf but it dosent seem to work. I tried arch supports (raises arch, cushioned) but they either work or don't work. Its really annoying to have to focus on this and not the game.
