Perhaps the most balanced part of the Nationals lineup is the heart of their order.
In 2012, the right-handed Ryan Zimmerman batted third. He finished the season hitting .282 with 25 home runs and 95 RBI.
Michael Morse typically hit fifth and is also right-handed. In only 102 games during the 2012 regular season, Morse hit .291 with 18 home runs and 62 RBI.
Right in the heart of it all was the lefty Adam LaRoche, batting clean up. LaRoche hit .271 with 33 home runs and 100 RBI. He led the Nationals in both home runs and RBI.
Davey Johnson has some flexibility in this matter. If Michael Morse is out of the lineup, Johnson can pencil in other right handers into the fifth spot to maintain the balance in the batting order. Likely candidates would be Ian Desmond or Jayson Werth.
But, Johnson may need this lineup flexibility sooner rather than later.
