Don Mattingly is expected to return as manager of the Miami Marlins next season, according to Derek Jeter.

Mattingly has one season to go on a four-year contract he signed when he joined the club in 2016.

"Is he going to be back in 2019?" Jeter said. "He's under contract. Yeah."

The Marlins will finish last in the National League East this season and Mattingly has a three-year record of 215-259.

"The one thing you can count on with Derek is that what he says, he's going to do," Mattingly said. "He talked about building the minor league system, building this thing the right way. I don't think there's one thing he talked about publicly that he hasn't backed up with his actions. You trust what he says and what he's going to do."
