The Chicago Cubs and the city have agreed on details of a $500 million facelift for Wrigley Field, including an electronic video screen that is nearly three times as large as the one currently atop the centerfield bleachers of the 99-year-old ballpark.

Under terms of the agreement, the Cubs would also be able to increase the number of night games at Wrigley Field from 30 to 40 — or nearly half the games played there each season. They would give Cubs chairman Tom Ricketts the ability to renovate the second-oldest park in the major leagues, boost business and perhaps make baseball’s most infamous losers competitive again.
