The Rangers have unsigned players too. More than the Twins, by that list.
I made a mistake. The guys with no money are signed, but for small amounts.
The Twins are tied to Aguiar and Bonifacio, who have not signed yet because they have late August birthdays. They are ranked 30 and 34 by BA, so I assume they'll make a significant dent into the 3ish million left for the Twins.
I don't know if the Rangers have unused money and signings lined up. If they are making a play for Otani I doubt it.
