Niese made one mistake and it cost him, as he allowed a two-run home run to Wilson Ramos in the seventh inning of the Mets' 3-0 loss to the Nationals on Sunday. Niese allowed just those two runs on six hits with seven strikeouts in seven innings. He has just a 3.55 ERA on the season, but is only 8-11 due to the moribund Mets offense.
