It would be wise for the Sox to pony up the money anyway. A creative lawyer can find aw ay around the print on the ticket, and the bad publicity isn’t worth it.
They have screens and nets behind home plate in ballparks. Why not extend the nets down the baselines? And yes, everyone should be watching the game and paying attention.
Unfortunately, what might come of this is that MLB will be forced to rig up additional protective netting around the ballpark, making it tougher to see the game from the good seats. I'm old enough to remember when the netting behind home plate was minimal - you really had to pay attention then and many people actually brought gloves to games. Not to collect a souvenir or to get it autographed - but to protect themselves!
