Astros sign Erstad

And for the most confusing offseason free-agent signing, come on down Houston Astros.

I know Ed Wade likes his veterans but where does Darin Erstad fit in Houston?

Lance Berkman is -- or should be -- entrenched at first base. The outfield should be solidifed with Carlos Lee, Michael Bourn and Hunter Pence.

Erstad may be a nice bench piece, but certainly there's someone in the Houston system worthy of a few at-bats at the major league level.
