Pirates announce 2018 Minor League staffs

PITTSBURGH -- The Pirates on Tuesday announced their Minor League coaching staffs for the 2018 season, introducing a new manager at Triple-A Indianapolis while keeping their championship-winning manager in place at Double-A Altoona.
Brian Esposito will move up from Class A Short-Season West Virginia to lead Indianapolis this year, the Bucs announced. Michael Ryan will be back in the manager's office for Altoona, which won the Eastern League championship last season.
Joining Esposito in Triple-A are hitting coach Ryan Long and pitching coach Stan Kyles. Hitting coach Keoni De Renne and pitching coach Bryan Hickerson will round out the Double-A coaching staff.
Gera Alvarez will return to Class A Advanced Bradenton for his second season as manager. Matt Ford will be the Marauders' pitching coach, while Butch Wynegar -- previously the Triple-A hitting coach -- will serve in the same role in Bradenton.
