After defending his team's fight and will all season, Mets manager Terry Collins said his team has "folded it up" following a 10-1 loss on Thursday to the Nationals that marked the Mets' sixth straight defeat and dropped them to 1-8 on their just-completed homestand. "Perception is reality in our game and the perception I have right now is we've folded it up," Collins said in a passionate postgame news conference.
