From game notes on reds.com:
A fan gained illegal entry into Narron's office in the home clubhouse following Wednesday's game. The fan quietly sat down in the manager's office and listened to the postgame press conference and remained after it ended before Narron asked what he was doing there. Security later escorted the unidentified man away without incident.
I mean, what the heck?! That's so strange, and yet so hilarious!
