He’s Nathaniel Lowe, recently of the Washington Nationals and quite possibly the only American to go by Nathanial since approximately 1872. In fact, he actually went by Nate early in his career, changing it back to his birth name only after his mama yelled at him.

Washington Nationals first baseman Nathaniel Lowe had one of the best games of his seven-year career Wednesday against the Kansas City Royals. Lowe hit his first-career grand slam and reached base two other times in a tight 8-7 win.

Boston’s new first baseman isn’t in Monday’s Red Sox lineup, which has a newly returned player in the leadoff spot.
