Nice job...great GM. That is a sick infield.
As for the guys to pick up I grabed Meche where I could im up in Seattle so maybe there was a home town bias but he is looking awesome.
Carter is good for some saves though he is in TB he has been getting a few wins on top so far as well.
Marte I like. He is pitching well, I think he will soon have the closer role, since Kroch sucks, but I havent been really researched what manuel has said so thats just my guess.
I also like Wells, a young guy but great potential. And Johnson, low strike outs but hes got the wins and 4 out of 5 quality starts is nice to see.
As for offence i would grab Payton, he seems like he likes CO and he has a great offence around him, or Robert his speed is nice and steals are scare this year.
I in my leagues, yahoo, looks like yours is to, I like to go with no offence on my bench and load up with pitching, a balance of relievers and starters and plug and play daily. It hurts me if one of my O guys goes down with an injury but it seems more consitant and reliable than plugging in a batter one day here one day there. Of course if you have a inning or game cap you might not want to do this.
Great Team though i like your GM-ing.
