2:22pm: Baseball America's Jim Callis reports that the A's signed Stassi for $1.5MM, the biggest deal ever for a fourth rounder. The Royals had recently set a new mark for fourth round players, awarding Chris Dwyer $1.45MM a few days ago. Keith Law of ESPN.com, who was right on this signing as well, notes that the A's have acquired a first-round talent in Stassi. Even if they don't sign first rounder Grant Green, they'll still have signed one top player.
2:15pm: Kevin Goldstein of Baseball Prospectus hears that the A's have agreed to terms with Max Stassi. Baseball America estimates that MLB recommends a $237k bonus for Stassi's slot, but it wouldn't be a surprise to see the fourth round catcher sign for considerably more.
