Scotland fans are gifted special edition blue tartan Red Sox jerseys and there are probably more of those filtering into the ground than red and white ones.
Tessie and Wally, the franchise's green monster mascots, appear in Highland dress near first base as the formalities began and the fans settled in.
Proceedings kick off with a respectful rendition of the Star Spangled Banner, before the Tartan Army gives an acapella blast of Flower of Scotland.
As the Sox toil in the early innings, the Scots find their voice and charm. Across the aisle at the back of block eight, one newcomer from the other side of the Atlantic is being educated about innings, pitching counts and the intricacies of on-field actions.
