Welcome to the Hall of Fame Goose Gossage:
The picture below is from the All-Star Celebrity Softball game held at Yankee Stadium a couple of weeks ago. I think that is Goose on the mound.
I was also lucky enough to see Gossage pitch in a real game in 1978. He actually blew a save in the game, but Graig Nettles bailed him out giving Goose the victory. I don't remember much about the game other than that they had to stop play twice due light failures in old Memorial Stadium.
