What is the cause of distortion in this photo?

Probably photographer error.   I used a Fujifilm XT-1 with the Fujifilm XF 55-200 to take this auto racing photo.   There is more than usual distortion (I think) in the background.  I know it is not a good photo.  But several I took had what I think is out of the ordinary distortion in the fencing and other background.  More than I recall in using a Sony or Nikon camera in the past.  I am panning and I expect a blurring background, but not the stretching that I see.  Or am I just doing a rotten job at panning?  I purposely haven't cropped or done other post-processing.
