The Nationals announced this morning that President Obama will throw out the ceremonial first pitch on Opening Day, when they face the Phillies at 1:05 p.m.
It will be the third time in the team's history the president has thrown the first pitch, following President Bush in 2005 and 2008.
MLB commissioner Bud Selig will also be in attendance for the game.
"Opening Day of the baseball season is a special event for our country and its importance has been reinforced by the 100-year history of Presidential participation," Selig said in a statement. "I am proud that President Obama will continue the long Presidential tradition of throwing out the first pitch of Opening Day in Washington D.C."
It will be the 48th time the president has thrown out the first pitch on Opening Day in Washington, and it comes 100 years after President Taft started the tradition on April 14, 1910, throwing out the first pitch before the Washington Senators and Philadelphia Athletics' game to open that season.
"Across the country, Opening Day is a celebration of the return of hometown baseball and the glorious days of spring," Nationals managing principal owner Ted Lerner said in a statement. "It's a time of renewed hope and optimism for fans everywhere. The Lerner and Nationals family are honored that President Obama will mark that moment with us at the home of the national pastime in the nation's capital."
