The Sox could also try to work out deals for the players they lost in the Rule 5 draft, thus enabling the drafting teams to demote those players to the minors if they needed to.
For example, Washington left 25yo catching prospect Drew Millas unprotected.
And Philly left 24yo LHP Erik Miller unprotected.
Both don’t seem particularly enamored with these players as much as many scouts (most orgs put Miller in the Phillies top ten).
Washington does have a clear path for Ward, so they might be reluctant. Philly would be stupid not to make a deal that would allow them to keep Song, whose career to date consists of 17 IP in low A ball 4 years ago.
Those moves won’t make the Sox immediate contenders, but that doesn’t mean either is a bad move…
