Changes might be coming to the Diamondbacks coaching staff — and they could be coming right after the season ends.

General Manager Kevin Towers said he will meet with manager Kirk Gibson on Monday to go over his staff and he expects they will decide within “two or three days” after Sunday’s season finale whether changes are necessary.

“If there are changes to be made” Towers said “we’re going to probably try to do them rather quickly.”

Towers said he hasn’t yet spoken with Managing General Partner Ken Kendrick or CEO Derrick Hall about possible changes but he reiterated Thursday that he does not expect to make a change with his manager.

“Ultimately they’re the (ones making the final call)” Towers said. “I’m going to tell them I think (Gibson) should definitely come back. I’d like their support as well. I haven’t had a chance to have a face-to-face with those guys. I would think that they would back my decision on that.”

Gibson’s staff is largely unchanged from the one that oversaw a 94-win club in 2011. That group which featured five former All-Stars was lauded for its impact on the organization’s worst-to-first turnaround.

But first-base coach Eric Young was replaced after last season and it appears more changes could be in the works particularly after the Diamondbacks fell short in multiple areas.

Gibson pitchers and catchers speak highly of pitching coach Charles Nagy and under his watch this season left-hander Patrick Corbin developed into a frontline starting pitcher. But at the same time the bullpen has registered a major league worst 29 blown saves and several pitchers struggled.

First baseman Paul Goldschmidt has developed into perhaps the best hitter in the league and a legitimate MVP candidate under hitting coaches Don Baylor and Turner Ward. But multiple players had down years and the lineup has been inconsistent.

There did not appear to be many issues with the club’s in-game tactical decision-making but if the Diamondbacks believe Gibson needs different voices around him they could look to replace bench coach Alan Trammell who is one of Gibson’s closer friends in the game.

The coaches of course aren’t the ones not living up to expectations on the field. But if the Diamondbacks want to make the case for changes the results justify them.

“I’ll make it easy” Gibson said. “I take 100 percent accountability of what goes on. It’s my responsibility to lead us. I reflect on those things and things that I can be better at. Again you can do everything right and it doesn’t mean you win. I know people look and try to fix blame on certain areas. They can put it on me. I have no problem with that.”

As for his coaches?

“I don’t think it’s fair to say that any one person any one group is the culprit for where we’re at” Gibson said. “As a whole group we are. We wear it together.”

Towers and Gibson each are signed through 2014. All of their coaches’ contracts expire at the end of October.
