A man is in a critical condition in hospital after falling 20 feet from a stand onto the field of play at a Pittsburgh Pirates Major League Baseball game.

The spectator fell over the railing at the Pirates’ PNC Park during the seventh innings of the match against the Chicago Cubs.

He received treatment from emergency services and the two teams’ medical staff before being taken to Allegheny General Hospital, the Pirates said.

“I’m thinking about his family and him right now,” Cubs manager Craig Counsell said.

“Obviously scary. I didn’t see it happen, but I saw it out there after the play. I just hope everything turns out OK.”
