Picking up balls in the batting cage that’s what this was all about according to former Miami Marlins hitting coach Tino Martinez.

Three different Marlins refused to pick up balls in separate incidents violating a standard practice during drills in which a coach “soft tosses” balls for players to hit Martinez said.

Martinez 45 confronted the players about it. The confrontations grew heated. Martinez admits to using vulgarity with each player and grabbing one of them second baseman Derek Dietrich by the jersey but not — as some reports suggested — by the neck.

On Sunday Martinez resigned after his actions became public apologizing to the Marlins organization for his behavior and acknowledging mistakes to reporters.

On Monday night he spoke exclusively by phone with FOXSports.com about the incidents that led to his demise saying they were one-time disputes that did not linger.
