Meteors crash on Earth with aliens inside them. One alien waits in the trees near a baseball field. It attacks a guy that goes into the outfield to retrieve a ball. Later this guy is in his car driving and an alien rips out from inside his body. I think the alien in the field impregnated him.
Later on, the alien that came out of the guy shows up at someone's house in the window. An old man is with a kid and the old man shoots the alien with a shotgun.
One other thing I do remember is that when the alien was shot it kinda blew up and cracked apart spilling acid like blood I think, like in the Alien movies.
I was young and turned it off after the shotgun scene cause I was scared. late 80's early 90's. White people, set in USA. don't remember any actors. Medium budget I guess. And I thought the old guy with the shotgun might be Wilfred Brimley but I checked his filmography and nothing seems to match up.
