FILE - In this April 14, 1936 black-and-white file photo, President Franklin D. Roosevelt prepares to throw the traditional first pitch in Washington. A hundred years ago, a portly right-hander, President William Howard Taft threw out the first pitch at a Washington Senators game, a weak lob from the stands to the great Walter Johnson. On Monday, the Nationals bring in the left-hander, President Barack Obama. (AP Photo, File)
