The St. Louis Cardinals and Chicago Cubs were delayed by fog at Wrigley Field for 15 minutes after the sixth inning Saturday night. The Cardinals led 2-0 when play was stopped and won 3-0. The crowd of 38,872 joined in singing John Denver’s “Take Me Home, Country Roads” as the delay began. The song has re-emerged during the World Cup soccer tournament, with U.S. players joining tens of thousands of fans in singing it at the end of  matches. The rare Saturday night game at the iconic North Side ballpark started an hour late due to rain, then fog billowed in from the north starting in the second inning and got denser. Players seemed to struggle tracking fly balls, but there were no misplays.
