On August 19,2017 my brother Gilbert L Silva got hit with a ball and he was taken to New York Presbyterian hospital by ambulance and the ambulance service is sending him a bill of 650.00 who is responsible to paid this bill Please advise

Should have caught the ball...

The back of all tickets your there at your own risk. By the time you hire a lawyer probably not worth it. Good luck

I would consider consulting with a attorney

Check with the stadium but there is a disclaimer on the ticket stub.

Unfortunately you are responsible for it, it is on the ticket of warning that the ticketholder is responsible for injuries not the Mets or MLB

you should ask the office in citifield because that's not your fault obviously
