Putz progressing; Reynolds experiences setback

PHOENIX -- D-backs right-hander J.J. Putz took a step closer to returning to action after throwing a simulated game on Thursday.

The news was not as promising for left-hander Matt Reynolds, who also pitched in a sim game Thursday, but had his outing cut short.

"Reynolds didn't go very good," D-backs manager Kirk Gibson said. "He's back seeing the doctor. He felt something. He's back in the evaluation stage."

Reynolds has been on the disabled list since June 10 with a strained ulnar collateral ligament (elbow). The hope was that he could avoid surgery through a rehab. Reynolds entered the clubhouse Friday with medical films under his arm and said he preferred to defer comment until after he spoke with the team's medical staff.

"I don't know that yet," Gibson said when asked if Reynolds might require surgery.

Putz, meanwhile, is trying to come back from a dislocated right pinkie. He is slated to throw another simulated game on Saturday and could return before the end of the season.

"We'll see how he is after that," Gibson said. "I hope and expect him to come back."

Future of closing trio unsettled heading into offseason

PHOENIX -- The D-backs could have a tough decision on their hands next spring when it comes to choosing a closer.

Brad Ziegler took over as closer at midseason after J.J. Putz injured his elbow and Heath Bell was unable to hang onto the role. Ziegler has converted 10 of 12 save opportunities this year.

"He's been great since he's been over here," D-backs manager Kirk Gibson said.

Gibson was then asked about whether Ziegler might fill that role next year.

Putz and Bell are both under contract for next year while Ziegler is eligible for salary arbitration. His time and success this year in the closer's role will likely mean he will earn more money through the arbitration process.

"I don't know that we're there yet," Gibson said about next year's closer. "I hope he wins about 15 games for us next year. We're just trying to get through this year and play it out like we should. And then they all turn into businessmen and a different phase of our season starts."

Last month, Putz praised the job that Ziegler has done and talked about how he understood why Ziegler would fill the role for the rest of the season.

The veteran then broke into a smile.

"But I'm going to take it back from him next year, I'll tell you that right now," he said.

D-backs to celebrate Hispanic Heritage Day

PHOENIX -- The D-backs' 15th Annual Hispanic Heritage Day, presented by Budweiser, will take place Saturday at Chase Field.

There will be an APS Street Festival from 2-3 p.m. MST prior to the 5:10 p.m. game between the D-backs and Rockies. The festival will feature the D-backs Luchador as well as members from Club Deportivo Coliseo.

The D-backs will give away 20,000 Miguel Montero bobbleheads to fans entering the game, and there will be Folklorico dancers and Mariachi performers throughout the ballpark prior to the game.

D-backs players and coaches will wear black jerseys with "Los D-backs" across the front. This is the sixth consecutive season the team has worn the jerseys, which will be available for auction following the game. The proceeds will benefit the Arizona Diamondbacks Foundation.

Prior to the game, the D-backs will present Maria Harper-Marinick, executive vice chancellor and provost for Maricopa Community College, with the Hispanic Community Leadership Award.

Other pregame recognitions will include leaders from Aguila Leadership Institute and Be a Leader foundation for their contributions in the Hispanic community.

Montero and the Arizona Diamondbacks Foundation will also present a check for $50,000 to the Ronald McDonald House prior to the game.
