I'm going to strongly suggest that you dump Horton & Jackson & get yourself another hitter. Those 2 are costing you $6.31 and you're never going to use them enough to justify the cost.
If there is an offensive C available, I'd consider that. Sundberg & Reed will provide you with no offense over the course of the season. If there's a CF w/ better offense than McDowell, I'd drop him & with the combo of $$$ from those 3 players you should be able to greatly improve your offense.
I advocate picking up Lance Parrish for your C & Lynn in CF & dumping Horton, Jackson, McDowell & either one of your catchers.
