The St. Louis Cardinals' game at the Chicago Cubs has been postponed due to a forecast of rain and cold weather.
A makeup date for Tuesday's postponement was not announced.
Lance Lynn, winner of at least 15 games in each of the past three seasons, was scheduled to start for St. Louis, and Jake Arrieta for Chicago.
St. Louis won Sunday's opener 3-0 as Adam Wainwright pitched six innings in a game that saw the debut of a large videoboard in left at Wrigley Field and long waits for fans to use the restrooms.
A renovation project kept some of the bathrooms closed during Sunday's game, and problems forced the temporary closure of other bathrooms.
