Ready for the playoffs?

The Nationals clinched their 4th NL East division title in the last 6 years last week. That was expected as they were the only team in the division actually trying to win this season. This season has seen numerous injuries and the returns to form of Gio Gonzalez and Ryan Zimmerman.
The bullpen was a disaster the first half of the season, but that has been remedied with the trades made in late July that brought Ryan Madson and Sean Doolittle from the A's, and Brandon Kintzler from the Twins. The offense has been mostly solid all year, but one thing that troubles me is their at bats late in games when they are behind. Too many AB's are quick and desultory, often taking less than three pitches. This needs to change.
