Minors hitting instructor Barkett resigns

MIAMI -- More organizational turnover is taking place with the Marlins. On Friday, Minor League hitting instructor Andy Barkett, who managed Double-A Jacksonville to the Southern League championship in 2014, handed in his resignation.

A Miami native, Barkett turned down an offer to stay with the Marlins. Currently, Barkett is managing in the Dominican Winter League. He plans to pursue other opportunities.

Barkett managed a number of players on Miami's roster, including J.T. Realmuto, Christian Yelich, Marcell Ozuna, Adam Conley and Justin Nicolino. He managed Jacksonville for four seasons, compiling a 294-262 record, before accepting a role to work with Minor League hitters.

The Marlins have made a number of changes to their Minor League staff since Marc DelPiano was named vice president of player development in September. Former big league infielder Joe Dillon was hired last month to be a Minor League hitting instructor. Also, Lenny Harris, who coached third base for the Marlins this year, is expected to take a Minor League assignment.
