You need more power. Drop Delluci and Wilkerson for the likes of Gibbons/Rios/C. Wilson.
Try to swap one of your starters for a good closer... maybe Haren for Street.
Good luck and have fun. Keep you eye on hot players that are free agents and scoop them up. Sometimes you can trade a flash in the pan player who is having an extroardinary week for a good veteran who is starting off slow. Last year I picked up Tino Martinez when he was really hot and traded him for Figgins
Thanks for the hep with mine...
