On Sunday, Guillen accused the Washington Nationals outfielder of using too much pine-tar on his bat. So to apologize and make amends, Harper sent Guillen an autographed bat. The catch is, he just signed the bat and had no idea who it was intended for. It's common for players to get autographs for each other. The Nats' Adam LaRoche completed the rest of the message, then smeared it with pine-tar and sent it to Guillen.
