According to Jim Callis, the Cardinals inked Carson Kelly to a $1.6 million contract, which is triple slot and more than any other team has gone over slot thus far this year. Here's the link from Trade Rumors.

If Ramsey and Wisdom never make it past Quad Cities, they will still be good signs because they helped us sign Carson Kelly. In addition to having a name straight out of Gangs of New York, Kelly appears to be a legitimate 2-way stud, and though they're focusing on developing him as a 3B (as they should IMO), he's young enough that, if he doesn't pan out with the stick, they can still try him as a pitcher. Outstanding sign for Kantro and Krew, very exciting news (if you're a huge nerd).
