Welcome to the cafe!
Your starting line-up is pretty good - definitely put Kaz into 2B, and you can put Greene in at SS, although there are obviously better ones around to trade for.
In a 12-team league, I wouldn't have Sledge or Gonzalez on my roster; I don't see them adding anything to your team. There must be better hitters who weren't drafted.
You have some good SPs, but your RPs are weak. Takatsu is your only closer, although Urbina may be traded to a team that needs a closer - keep an eye on him.
Again, I wouldn't have Cruz, Jennings, Lima or Felix Rodriguez on my roster.
See if Adams (Mil) or Speier (Tor) went undrafted - both are scheduled to start the season as closers, and may have slipped through the net.
Who else is available on the WW?
