Lacrosse and Vinyl Fencing

I'm not quite sure what to do.

This...

 Which leads to this...

This has happened too many times and last time we got it fixed, we thought it would be the last.  Conner's only in 9th grade.  We have 3 more years of this!  I would just let it sit until it was all over and fix it once and for all, but see on the other side of that hole?  That would be our neighbor's backyard. There are several boys on the lacrosse team that live in our neighborhood.  There are several fences that look like this.  Too bad we don't share yards so we could just fix it when it looked like swiss cheese.
