Showing some work...
If we sign the Seniors for 10k, which is typical Sox behavior, we save about...
6th- 365k
8th-222k
9th-189k
10th-175k
That totals out to 951k in savings. The 7th round pick Fox is also the Jr 5'9" reliever who goes 89-92mph, so I can't imagine he gets full slot either at 293k either, but even if I don't count him, that is where the extra million dollars comes from.
I would guess we have an extra million dollars to spend today, as a complete educated guess.
