The increase in night games is part of the "framework" the mayor, Cubs chairman Tom Ricketts and 44th Ward Alderman Tom Tunney announced in April as part of the team's renovation plans for the 99-year-old ballpark. The Cubs want to pay for the renovation work through expanded advertising.
The Cubs will be able to schedule 35 night games outright, starting in 2014. That number could increase to 46 per year if Major League Baseball wants more night games as part of its national television contract. The Cubs have played 30 night games a season at Wrigley since 2004.
This season, the Cubs will be able to move the first pitch of six Friday games from 1:20 p.m. CT to 3:05 p.m. CT. Those dates have not been announced.
