Well first off welcome to fantasy baseball!
For a 14 person league especially (H2H or roto by the way?), you have a fantastic offense. Your OF is a little weak with Kearns and Gomez (Who I'm guessing you slotted in for SBs), but other than that great... but then that pitching.
You probably know this from standings in your league, but your pitching is extremely weak. Smoltz is a clear #1, but the rest of the staff doesn't cut it. Vazquez helps with K's, and Billingsly will probably turn it around some, but overall a poor staff. In addition, your only closer has been doing poorly and may lose his job shortly..
As with fantasy football, trade from your strengths to shore up your weaknesses. Look to move Zimmerman or Blalock for a middle tier closer or middle starter. Watch the Who to Start/Bench thread and spot start pitchers for good matchups. See what you can get for Russel Martin (Stealing much less this year) pitching wise, if anyone is selling low on Sabathia, Verlander, Oswalt go get them.
...Boston papers now and then suffer a sharp flurry of arithmetic on this score; indeed, for Williams to have distributed all his hits so they did nobody else any good would constitute a feat of placement unparalleled in the annals of selfishness. -Updike
