The 2008 Marlins biggest(?) problem

In 2007 the biggest problem with the Fish was their awful D as hits were dropping in everywhere as measured by DER and team zone rating.

It's too early in the season to focus too much on any one player, as they don't have enough AB's to have a good sample.  But the team stats have enough events that we can start to see what is going on with the whole team.

In 2008 the D is much better, as they are no longer worst in the league.  Houston, Milwaukee, Pittsburgh and San Francisco are all arguably worse.  Maybe Hanley's health and having a real 3rd baseman are helping.

But the one thing that jumped out at me is that they are 29th in all of baseball in team OPS versus LHP.  As you guys see more games than me, what is going on there?  I thought the Marlins were loaded with RH batters.
