NEW YORK -- The first pitch of the Mets' home game against the Pirates on Wednesday was delayed 40 minutes because of a water main break under a street adjacent to Shea Stadium and Citi Field. Excavation on 126th Street, involved in the construction of the Mets' new home, ruptured the main at about 12:30 p.m. ET, Mets vice president David Howard said.

The reason for the delay was the club's sense that Shea Stadium could not be properly operated with diminished water pressure. Howard said the upper levels of the park already had been affected by the scheduled game time, 1:10. Fans were alerted of the delay at 1:07 p.m. Oliver Perez threw the first pitch at 1:50.
