Spidey Up Against the Wall - S1.E4

At a New York Mets baseball game, a mutated half-human, half-wall creature (Jim Boyd) sneaks up behind outfielder "Gumbo" Grace Ivy (Skip Hinnant) and causes him to miss a routine fly ball. The umpire (Morgan Freeman) is also knocked down. Spidey catches the Wall, but is ejected from the ballpark because spectators are not allowed on the field. The opening screenshot shows the Wall bumping Spidey.
