The following month, July 7, 1909, there was a breakthrough of sorts. On that date Grand Rapids and Zanesville of the Class B Central League played a night game at the Ramona Athletic Park, Grand Rapids, Mich. The mayor of Grand Rapids, George Ellis, officiated as umpire.
The Grand Rapids Herald of July 8, 1909, reported that Grand Rapids won the seven-inning contest, 11-10, over Zanesville before a crowd of 4,500 fans “drawn by the novelty of the play by artificial light.” The Herald also stated that “Outfielders had their troubles in judging the balls hit in their direction but the light was perfect for the batters, and how they did land on the ball.”
The question immediately arose as to whether the contest would count in the league standings. It did not. There was a rule of that period which prohibited league games from starting later than two hours before sunset.” —http://research.sabr.org/journals/under-the-lights
