One user over at r/Nationals was serving some time in jail. For what? No idea. But on the last day of his stay, he claimed he saw Jayson Werth and told the bearded one he was at Game 4 of the NLDS in 2012. As photographic proof, he showed what he claimed to be an autograph from Werth on his inmate handbook. Busted Coverage compared the signature to a known Werth autograph… and it looks similar.
Also, as additional evidence, signing autographs in jail is about the Jayson Werth-iest thing you can do.
