Ghost in the outfield at Minute Maid Park?

HOUSTON – There's something strange at Minute Maid Park. So who are you gonna call?

Wall Street Journal reporter Jared Diamond captured what appeared to be a strange, white smoke hovering over Minute Maid Park during a game between the Houston Astros and New York Yankees on Tuesday.

Diamond suggested that it may have been a ghost when he shared a photo on Twitter.

People had fun with Diamond's tweet, replying to him with GIFs from the "Angels in the Outfield" movie and referencing "Ghostbusters."

We're not exactly sure what it was Diamond photographed. What do you think it is? Could it have been legendary sportscaster Milo Hamilton?
