The Cubs signed 14th rounder Dillon Maples for $2.5MM, according to Kendall Rogers of Perfect Game USA (on Twitter). Though they selected the right-hander 429th overall, the Cubs signed Maples for as much as MLB recommends offering the fifth overall pick. Top Cubs pick Javier Baez signed for $2.65MM after being selected ninth overall earlier tonight. The 19-year-old Maples stands 6'2" and weighs in at 195 pounds.
