CIN@ARI: Cahill fans three in two innings of relief

PHOENIX -- With the way he was pitching, you knew something had to give when it came to D-backs right-hander Trevor Cahill.

It finally did Monday as the team designated him for assignment -- meaning it has 10 days to trade, waive, option him to the Minors or outright him to the Minors.

Cahill struggled as a starter at the beginning of the year and after showing some initial improvement when he was moved to the bullpen, his struggles continued. In 19 games (four starts) he was 1-6 with a 5.66 ERA.

The team has met with Cahill over the last several days to discuss some options.

The most likely appears to be the team would option him to the Minor Leagues -- maybe Class A Advanced Visalia -- where he could work out some of his issues as well as get stretched out to become a starter, a role that both parties think he's best suited for.

Because of his service time, Cahill has the right to decline an option and therefore become a free agent.

"We've talked to Trevor at length, we talked to his advisor," D-backs general manager Kevin Towers said. "There's a gameplan in place for what we're ultimately going to do, but as of right now he's just designated. Because of service time and where he's at, there's a lot of hurdles and hoops you've got to jump through. The reason I can't be totally upfront is there are a lot of things that can still happen in the next couple of days. I hate to put the cart in front of the horse right now."

Should Cahill decline to go to the Minor Leagues, he would become a free agent with the D-backs still on the hook for the nearly $18 million left on his contract. Cahill is still owed about $5.6 million the rest of this season and $12 million in 2015. The team holds options for 2016 and 2017 with a $300,000 buyout for the first option.

Cahill seemed to indicate that he would accept an option to the Minors without definitely saying that.

"The way I'm throwing right now I don't know necessarily what the outcome of that would be," Cahill said of electing free agency. "I just want to get back to being a starter and right now I'm not built up. I'm sure they've got a plan and I trust them and I feel like they'll do right by me. They haven't given me an indication that they wouldn't. So I'm just going to do whatever's best for the team. I like playing here. I want to stay here, but I want to get better and be the guy that I can be."

Putz activated, Harris recalled as Chavez lands on DL

ARI@CHC: Putz turns double play with bases loaded

PHOENIX -- The D-backs added a pair of arms to the bullpen Monday by recalling pitcher Will Harris from Triple-A Reno and activating J.J. Putz from the 15-day disabled list.

Harris, who began the season with the D-backs, had a 1.12 ERA in 20 games for Reno.

Putz, who was placed on the DL on May 4 with tightness in his right forearm, had made two rehab appearances for Reno late last week.

To make room on the roster, the D-backs designated right-hander Trevor Cahill for assignment and placed third baseman Eric Chavez on the DL with a sprained left knee.

Chavez has been battling the knee issue since Spring Training and it finally reached the point where the club had no choice but to DL him.

The moves leave the D-backs with 13 pitchers and 12 position players rather than the usual 13 position players and 12 pitchers.

While admitting it's not an ideal situation because it leaves him short a man on the bench, D-backs manager Kirk Gibson said it was necessary given the way the bullpen has been taxed recently.

Towers to undergo vocal cord procedure in July

Towers, Montgomery on first round selection

PHOENIX -- D-backs general manager Kevin Towers will undergo surgery to repair his right vocal cord on July 7 in New York.

Towers first had trouble with his vocal cord last year just prior to last year's First-Year Player Draft in June.

The condition improved a bit, but then this spring he once again began experiencing problems with his voice.

Towers will have his right vocal cord replaced by one from a cadaver.
