[UPDATE 10:34 a.m. EDT: Marlins name GM Dan Jennings as new manager]
The Miami Marlins fired manager Mike Redmond on Sunday after the team slumped to a 16-22 record, the National League club said.
Miami have struggled despite making significant offseason moves in a bid to end a decade-long playoff drought.
The Marlins made the announcement shortly after the team escaped being no-hit by Atlanta's Shelby Miller in a 6-0 loss to the Braves. Miller lost his no-hitter after two were out in the ninth inning.
"Hopefully a new voice will spark and motivate our guys to play as capable as we know they are capable of playing," Michael Hill, the Marlins' president of baseball operations, said in a statement on Twitter.
Redmond, 44, was in his third season as the team's manager. He had a 155-207 record and was dismissed along with bench coach Rob Leary.
The Marlins said they would name a new manager on Monday.
The team last made the playoffs in 2003 and went on to win the World Series. They have not had a winning record since 2009.
In hopes of ending the streak, the Marlins signed hard-hitting Giancarlo Stanton to a record 13-year, $325 million contract and acquired several new players through trades and free agency.
But the turnaround has yet to materialize as the Marlins stood fourth in the five-team National League East after losing six of their last seven games.
