On May 23, 1926 — Hack Wilson smacks a 5th-inning home run‚ a rare blast off the Wrigley Field scoreboard‚ situated at ground level‚ to start a rout of the Braves. The Cubs score 7 runs in the 8th inning to win, 14 – 8. Sparky Adamscontributes 4 hits for Chicago. Later that night‚ Wilson and a few others are arrested at a friend’s apartment for drinking beer in violation of the Prohibition Act. The scoreboard will be moved to the left field corner in 1937‚ before one will be built atop the newly-built bleachers.
