Adam Dunn hit a mammoth two-run jack in the sixth to give the Nats a 3-2 lead. That might be it for a while, too, unless Strasburg is removed soon (as he probably should be)—Strasburg has limited his changeups and kept most the ones he has thrown down in the zone, and he looks pretty much unhittable.
Josh Willingham just added another solo homer to put the Nats up by two, and Karstens is done.
