In this April 10, 2014 photo, scoreboard operator Darryl Wilson keeps up with the game as he watches from inside Wrigley Field’s iconic scoreboard as during a baseball game between Pittsburgh Pirates and Chicago Cubs, in Chicago. Wilson mans the two top floors, little more than scaffolding of the three-level scoreboard, tracking scores from around baseball and changing scores and the uniform numbers of pitchers as managers in those games bring in relievers. With Boston’s Fenway Park and Wrigley the only two stadiums in the majors with primary manual scoreboards, it has been a job largely shrouded in mystery until the Cubs allowed The Associated Press climb the steel ladder through the steel floor of the scoreboard for a rare visit to mark Wrigley’s 100-year anniversary.
