– Even the mother of the Miami Marlins' new manager is questioning the wisdom of the choice.

Marlins General Manager Dan Jennings, 54, was selected Monday to replace Mike Redmond in the dugout. Jennings has 31 years of experience in professional baseball, but he never played in the majors and never has managed.

"It is outside the box, I will not deny that," Jennings said at a news conference. "My mom, whom I love deeply, asked me, 'Are you crazy? Have you lost your mind?' "

Redmond, a former Twins catcher, was fired Sunday after the Marlins were nearly no-hit in a 6-0 loss.

The defeat dropped Miami to 16-22, but Marlins President David Samson said a change had been in the works since the Marlins started 3-11.

In Jennings' first game Monday night, the Marlins lost 3-2 in 13 innings to Arizona.

The shake-up was the latest orchestrated by owner Jeffrey Loria, reinforcing his reputation for impatience. Jennings is Loria's sixth manager since June 2010.

"Jeffrey Loria makes me laugh!" former Braves third baseman Chipper Jones tweeted.

No other candidates were considered, Samson said, in part because the Marlins have gone through so many managers already.

"There's nowhere else to look anymore," Samson conceded. "We're running out."

The Marlins consulted with Commissioner Rob Manfred and complied with Major League Baseball's minority hiring requirements, Samson said.

Jennings' only coaching experience was in high school in Mobile, Ala., in the 1980s.

"There are going to be cynics," he said. "There are a lot of managers who arrive in that chair via a different path. We now have a new path."
