use lopez instead of womack. too lazy to check lopez's position eligibility, but i'm sure with the flexibility lugo gives you you can use him somewhere over womack in your lineup.
3 speed only guys are too much to be using at the same time. and on top of that damon himself seems to be lacking power this year. i'd try to trade damon for a more typical 30 90 OF, like jose guillen or luis gonzalez type. not a sexy name, but gets the job done.
you could also use a SP, but i think i'd worry about your hitting first.
don't trade morneau. he should be fine.
if you want to go big and fill in multiple holes at once, you can trade a-rod for like 3 players. you wouldn't even need to get back a 3B since you got aramis.
something like arod + damon should get you something like two 30 100 OFs and a 14 3.00 200 pitcher.
