This shouldn't be happening, not like this. It's not that the Nationals have won nine straight games. And it's not that they've won in walk-off fashion four of the last five nights. It's that they've won three of the last four nights after blowing a lead in the eighth or ninth inning.

Really, who does this?

"I mean, just absolutely epic," Bryce Harper said. "That's the best word I can put on it for you. It's been incredible."

The events taking place each evening on South Capitol Street are beginning to defy explanation. Four nights after rallying from 3 runs down to beat the Pirates, three nights after watching Rafael Soriano melt down in the ninth before they came back to win in the 11th, two nights after watching Tyler Clippard blow his own ninth-inning lead before they again came back to win in the 11th, they did it yet again.

Leading by two runs in the eighth, the Nationals saw Clippard surrender another game-tying homer, only to pick up their All-Star reliever by producing another winning rally in the ninth, beating the Diamondbacks 3-2 for their ninth consecutive victory.

At this point, it sure looks like Matt Williams is drawing them up this way, going for maximum drama at the expense of everyone's blood pressure.

"No, no. Not even close," the rookie manager insisted. "That's not the way you draw them up. But they don't stop fighting, that's for sure."

The Nationals find themselves in this position — winners of nine straight, owners of a 7-game division lead, an NL-best 19 games over .500 — thanks to an elite rotation (starters have given up 10 total earned runs during these nine games) and an opportunistic lineup that thrives in pressure situations late (they've scored 27 runs from the sixth inning on during the streak).
