Report: D-backs fire Kevin Towers

— -- The Arizona Diamondbacks have fired general manager Kevin Towers, according to

Arizona, which will announce the firing Friday morning, is 59-81 and 19 games behind the Los Angeles Dodgers in the NL West entering Friday.

Towers quickly found success after joining the Diamondbacks late in the 2010 season, as the team won the NL West title in 2011 with a 94-68 record. That changed, however, as Arizona sputtered to consecutive 81-81 seasons the next two years.

Speculation had swirled over Towers' status since the Diamondbacks hired Tony La Russa, a Hall of Famer who ranks third behind Connie Mack and John McGraw with 2,728 career managerial wins, as their chief baseball officer earlier this season.

After the hire, Towers expressed confidence that he could work with La Russa and show that he was the one to run the Diamondbacks' baseball operations moving forward.

"I have a lot of confidence in my ability to be a GM, and I think that if Tony gets an opportunity to spend some more time around me, he'll see that he's got a very qualified GM that's in the organization with him," Towers said at the time. "I'll bet on myself, and if I'm dealing with a baseball lifer here, I think he'll be able to recognize good baseball people.

"I'm hoping that we help one another. And as we get to talk, I'm hoping he'll have the confidence in the very near future to let me run the club as I have been. But everything will go through him and be shared with him. You'd like to think that our vision and everything is on the same page."

Before joining the Diamondbacks, Towers served as GM of the San Diego Padres from 1995 to 2009.
