Brandon Nimmo began Monday below the Mendoza line and proceeded to have the kind of game a manager named Mendoza could love.

Brandon Nimmo hit a grand slam and matched a franchise record with nine RBIs, helping the New York Mets pound Washington Nationals 19-5 on Monday. Nimmo also hit a three-run drive in his seventh career multihomer game.

Facing former Mets right-hander Trevor Williams in the bottom of the second, Mark Vientos and Nimmo set the table with back-to-back one-out singles. Francisco Alvarez drove a double to the right field corner to score Vientos and put the Mets on the board, 1-0.
