According to the New York Mets' official web site, there is a press release announcing the rain out, and future plans. Below are the details...
Saturday night’s game has been rescheduled for Sunday, June 15, at 1:10 p.m.
Tickets from Saturday, June 14th will not be allowed for Sunday.
Tickets for the regularly scheduled June 15th day game are good for both the 1:10 P.M. game, and the night game, for a good old-fashioned single-admission, Father’s Day doubleheader. The night game will begin shortly after the 1st game ends.
Tickets for tonight's game will not be valid for any future game.
Fans holding tickets from Saturday's game, wishing to attend the June 15th games should follow standard rain-check ticket exchange policy on Mets.com.
The Associated Press reports…
"Heavy rain and lightning rolled through the area about two hours before game time, but by then the tarp had already been on the field for some time. The few hardy fans sitting beneath the overhangs at Shea Stadium cheered each clap of thunder in the distance, and at one point those down the right-field line tried to start a very wet wave.
About an hour into the delay, Rangers second baseman Ian Kinsler raced from the dugout and dived across the tarp over the infield, by then a giant Slip 'n Slide. Josh Hamilton, Michael Young, Gerald Laird, Josh Rupe and Milton Bradley -- bad knees and all -- followed suit to a big ovation from those still in the stands.
Shea Stadium security ushered them off the field, drawing a chorus of boos, but they emerged moments later and slid across the tarp one more time."
