I am in this sluggers league (hitting only), and I noticed I have way to many 1B. I would like to get rid of?

Pick up someone who plays a position where you're weak at. I believe Sandoval plays third also, and Morales plays outfield. But I don't know if Berkman still qualifies as an outfielder. If you want an upgrade at second base, go with Uggla, if you want shortstop upgrades, go with Young or Tejada, if you want outfield upgrades, go with Hawpe, Ludwick, Span, Ross, or Heyward. Personally, I would drop Berkman for Uggla. They both have pretty similar stats (Uggla has lower batting average though), but Uggla plays in a position where people who hit like him aren't common.
