Mathis signed for full slot. MLB's tracker does a bit of rounding, but BA has the full dollar amount at $1,681,200.
I may have butchered the math, but the Cubs should still have $515 left to spend before incurring pick penalties.
As a heads up, updated slot figures are here. Slot for pick 203 is now $237,500. Jim Callis found out about the increase either right before or during the draft, then posted 'em all on Wednesday.
Y'all are for real? Come on now. These are high school and college athletes who we're all horsefeathering rooting for to succeed and make it playing an awesome game. There's nothing wrong with gravitating toward some ballplayer in any sport who you want to see live up to their potential and be in the Hall of Fame. It's totally cool to like a prospect and be wrong about it. There's so many players who are never going to be drafted, let alone make it to the Majors. It's not a bad thing to be one of their few crazy supporters while they're working on a dream.
