I'm all for Hornsby regardless of park, but he needs someone to bat behind him with some threat. Papelbon is not anywhere near worth 5% of your budget. There are may things you can do by downsizing that pen, consider a platoon somewhere (I often platoon at DH or 1b to save cap money).
get some cash out of your pen and buff up the bats.
2.47 McClure (no BP singles) looks like a great fit for your park. Nelson, Face, Hall, Myers, Brandom, Hiller, Moore, Wolfgang.......there are a lot of good choices to replace Papelbon who will be able to churn out many more quality innings.
also, (and don't get me wrong, as I love me some stellar defense), but I suspect you will be frustrated at how non-productive Crossetti and Wilson will be.
Best of luck and do not forget to have fun with the process!
