PHOENIX -- Left-handed pitcher Randy Wolf exercised the out clause of his Minor League contract with the D-backs and was granted his release from the club on Wednesday.
Wolf signed with the Marlins, who are giving the veteran a chance to join their rotation.
Wolf, who signed with the D-backs last month, went 5-1 with a 4.50 ERA in six starts for Triple-A Reno, a span of 34 innings. He struck out 35 batters and walked 18 for the Aces.
"I think he enjoyed his stay down there in Reno, and he pitched very well, but at this point in time and the way our starters were throwing, we didn't want to put him in the bullpen," D-backs general manager Kevin Towers said. "I think he wants to start. We didn't see anybody we wanted to take out, so he opted to take his out [clause]. We just decided to go with younger players."
D-backs starters are 6-2 with a 3.01 ERA with six quality starts in the first 11 games in May. What's more, rookie Chase Anderson allowed one run and two hits in 5 1/3 innings against the White Sox on Sunday in his big league debut.
"[Wolf's] name came up in some of our discussions, but we felt where the club was at, is the message to your fan base when you're losing to bring up an aging veteran? Is that really the direction this organization should be heading?" Towers said. "We felt it was better to give the opportunity to some of the young guys that have been performing in the Minor Leagues."
Wolf is 132-117 with a 4.20 ERA in 376 appearances (368 starts) over parts of 14 seasons. He didn't pitch in the Major Leagues last year because of Tommy John surgery, and last pitched in the big leagues for the Brewers and Orioles in 2012.
Ziegler honoring firefighters with youth field dedication
PHOENIX -- D-backs reliever Brad Ziegler continues to solidify his reputation as a standup guy on and off the field.
On Friday, the pitcher will participate in the dedication of the 34th field in the "Diamonds Back" Youth Field Building Program for youth league baseball players in Prescott, Ariz. The field is a tribute to 19 firefighters who lost their lives last year while battling a wildfire near the Northern Arizona town of Yarnell, a city located about 85 miles northwest of Phoenix. The firefighters killed were members of an elite fire suppression unit known as the Granite Mountain Hotshots, based in nearby Prescott.
"It's a way to give back to the community that has a lasting impact for multiple reasons," Ziegler said. "No. 1, it obviously gets kids excited about baseball and they get to play on a really nice field. But No. 2, it honors the memories of those fire fighters, and that's really special to have my name on the field and it's truly an honor to be associated with that. Those firefighters and their legacies is what we really want to honor with this."
On the mound, Ziegler entered Wednesday's series finale against the Nationals riding a 19-game scoreless streak. The reliever also had a 29-game scoreless streak from May 31-Aug. 12, 2008.
"Honestly, I couldn't have told you how long it was," Ziegler said. "I feel like I've been throwing the ball pretty well and guys are making plays behind me. The goal is to get wins. We've had a tough go of it to begin the year, and if there is a way to contribute, it doesn't matter what my line is as long as we win the game."
Marte impressing in second stint with D-backs
PHOENIX -- D-backs outfielder Alfredo Marte is determined to make the most of his time with the big league club this time around.
Marte entered Wednesday with four hits, including three doubles, in his first 12 at-bats since being recalled from Triple-A Reno on May 2. He was batting .342 with five doubles, 11 RBIs and nine runs scored in 26 games for the Aces before his promotion.
"It's great to be back in the big leagues and sharing this experience with the guys," Marte said in Spanish. "It's hard not to play every day, but it's a process and you learn how to adjust. Nobody likes to be on the bench, but you just wait on your chance to show what you can do and help the team how you can."
Marte hit .186 with three doubles in 22 games for the D-backs last season.
"I feel like the experience has helped me," Marte said. "I learned a lot my last time here. I'm a little more comfortable and I think it is showing when I play."
• Archie Bradley, who is on the Minor League disabled list with a mild flexor strain, will start a throwing program in four or five days, Towers said.
It's unclear when Bradley will pitch in a game.
• "We are probably going to take it slower. There is no real rush," Towers said. "It's based on how he feels. It's going to take a while to build his arm back up, so I imagine he'll be in extended [spring training] for some time, so we can build him back up again so he can get to 75 or 80 pitches."
• Dave Duncan, D-backs special assistant to the GM and pitching consultant, will be inducted into the Missouri Sports Hall of Fame in Springfield, Mo.
• Cory Hahn, who was drafted in the 34th round of the 2013 First-Year Player Draft by the D-backs, graduated from Arizona State University. He was paralyzed during a game in his freshman season.
