NEW YORK -- Steady rain in the weather forecast for the Bronx postponed Tuesday's scheduled series opener between the Cubs and Yankees. A day-night doubleheader is now slated for Wednesday, starting at 12:05 p.m. and 6:05 p.m. CT.

Chicago's Jason Hammel (2-0, 2.63 ERA) will start the opener, and Travis Wood (0-1, 2.92) will start the second game. Masahiro Tanaka (1-0, 3.21) will open the twin bill for the Yankees, and Michael Pineda (1-1, 1.50) will pitch in the nightcap.

New York's commemoration of Jackie Robinson Day -- complete with a celebration and plaque dedication for the life of Nelson Mandela -- was also postponed until tomorrow.
