Where does my fantasy baseball team need upgrades?

You lack a proven big HR hitter, ideally in the OF. Try to trade for Adam Dunn; proven 40 HR power but has a low BA so he could be obtainable if you package an OF with one of your closers (sell a big name like Wagner; saves are really easy to pick up later in the season and you have 6 closers anyway). Dunn would also work well for you since you have Ichiro's high batting average to offset his .250-260 average. Definitely a solid all-around team though.
