I think it is a safe bet to say that the power surge we had over the past week is unprecedented in Nats history. I certainly don't remember anything like this. If this keeps up 100 may be selling us short.
Note: Twenty-five games left, and the 2012 team just passed the season record for home runs by a Washington team: 163 by the 1959 Nats. The old team had four sluggers (walk around the concourse, and just behind home plate you'll see who), but the 2012 team has power all through the lineup. A good sign.
