The video shows Martinez in a hotel room with other members of his team there to console him, including outfielders Marcell Ozuna and Tommy Pham and catcher Franciso Pena.
Describing what happened, a rough translation of the video indicates Martinez says "a ghost has appeared right here in the room." The caption also mentions how he "can't sleep alone" because of the "ghost in my room."
The video is in Spanish, but it isn't hard to tell that Martinez is a little frightened. It may only get worse for him as he takes the mound Thursday night against the Brewers.
