Opening Day is special for #27: William Howard Taft (Nats President “Bill”), the 27th President, is well known as the first to throw out a first pitch on Opening Day at Griffith Stadium in DC in 1910. If you google, it there is a video on-line at MLB showing the event of Taft throwing from his sideline seat to HOF Senator Walter Johnson, who threw a one-hit shutout against the Philadelphia Athletics. Legend has it that Taft also started the 7th-inning Stretch by standing up in the 7th to stretch his legs. The Ironman President of Opening Days was John F. Kennedy who not only threw out the first pitch, but sat through all 27 innings, including a rain delay in 1962. The most recent Opening Day Pitch took place in 2010 by Barack Obama at Nats Park.
