Julio Rodríguez / Michael Harris II

Yesterday afternoon's contest between the Seattle Mariners and the Atlanta Braves was tremendously exciting from start to finish, and thanks to key performances by Seattle's Julio Rodriguez and Atlanta's Michael Harris II, a new piece of Major League Baseball history has been created. This was the very first time that two players aged 21-years-old or younger hit multiple home runs in the same game, after both players notched two for their respective Clubs. When all was said and done, the Mariners would leave victorious, 8-7.
