R.A. Dickey was changing speeds with his dancing knuckler and pumping in plenty of strikes. And by the time he made it through six spotless innings Saturday, he figured he just might be able to pitch the first no-hitter in New York Mets history. Dickey took his no-hit bid into the seventh, David Wright hit a tiebreaking double in the eighth and New York beat the slumping Philadelphia Phillies 2-1 in the opener of a day-night doubleheader, sending the NL East champions to their seventh straight loss.
