Darin Erstad to the Astros

Unless you're in a very deep NL-only league and "grittiness" is a scoring category, this shouldn't affect your fantasy team except in one way:

Is it possible the Astros are dumb enough to give Erstad playing time over Michael Bourn, who is a big-time steals sleeper? The little guy stole 18 bases last year with only 132 plate appearances. He did pinch-run 35 times, so you have to take that into account, but still, the guy is fast.

Keep an eye on those crazy Astros this spring to see if they give in to the irresistible grittiness of Erstad, thus devaluing Bourn in your fantasy draft.
