Washington general manager Mike Rizzo got into a shouting match with second base umpire Jim Joyce in the hallway between clubhouses moments after the final out of the New York Mets' 9-7 win over the Nationals on Thursday night.
It followed the Nationals' attempt to rally in the ninth inning, which was thwarted when Jayson Werth was called for an illegal takeout slide at second base.
The call was upheld following a replay review, giving the Mets a double play after Asdrubal Cabrera had made a diving stop at shortstop of Daniel Murphy's sharp grounder.
