The Baltimore Orioles, a professional baseball team, visited Bostons Fenway Park to play the Boston Red Sox, another professional baseball team. Ross Grimsley was a picture for the visiting Baltimore club. During one period of the game, Grimsley was warming up in the bullpen, throwing pitches to a catcher. During this warm up, Boston spectators in the stands heckled Grimsley. After Grimsley had completed warming up, Grimsley wound up as if he were going to throw the ball in his hand at the plate but then turned and threw the ball at one of the hecklers in the stand. The ball traveled at about 80 miles an hour, passed through a wire fence protecting spectators, missed the heckler that Grimsley was aiming at, and hit another spectator, David Manning, Jr., causing injury. Manning sued Grimsley and the Baltimore Orioles. Are the defendants liable? Fully explain your answer
