What can I do to improve my fantasy baseball team? HELP!!?

First thing, don't panic! The season is early and your team overall doesn't look that bad. Out of the free agents you've listed, I might consider dropping Tejada or Figgins for Zach Britton and/or Raburn for Gordon. But I wouldn't do anything drastic. It's way too early to evaluate how players are going to perform this year. Guys get off to hot starts and slow starts. Just look at Pujols...do you think he's going to have a bad year? NO. Just ride it out for at least 4-5 weeks before making any major moves. Best of Luck!
