MILWAUKEE -- An MRI on reliever J.J. Putz's right forearm revealed no damage in addition to the tightness that landed the reliever on the 15-day disabled list.
"His MRI looks good," D-backs manager Kirk Gibson said Wednesday. "I think the shutdown is seven to 10 days, and then he'll start a throwing program. Just try and strengthen it up. Just a mild irritation."
Putz, 1-0 with a 5.40 ERA, was placed on the disabled list Tuesday, retroactive to Sunday.
Gibson said he thought an estimated timetable of three to four weeks for Putz's return was reasonable.
"We kind of went through this last year with him," Gibson said. "Try and get it strong, and then you start going into a throwing program and try and get his arm strength up. Maybe that's a good timetable. You never know when you start back up if you have any setbacks.
"What happens, you get irritation, you get inflammation in there, you usually get fluid in there, then it's hard to get it calmed down. When you calm it down, then you start it back up and you hope it doesn't flare back up."
Hill sits in finale despite success vs. Brewers
MILWAUKEE -- Aaron Hill, who delivered the game-winning two-run homer in Tuesday night's 7-5 comeback victory over the Brewers, was held out of the starting lineup on Wednesday, despite hitting .432 against Milwaukee since 2005.
"This was planned," D-backs manager Kirk Gibson said prior to Wednesday's game. "I gave [Martin] Prado a day off last week. I told Hill he was going to get a day off this week. We kind of talked three, four days ago, and asked him where he thought in his mind it would be, and we kind of decided today.
"I told Prado last week, 'I don't care if you get five hits, you're going to be off tomorrow.' He got three hits that day. And I told Hill the same thing. He had a pretty good game yesterday, so maybe I should start telling them that more often."
Gibson said he was aware of Hill's track record against the Brewers, but he wanted to take advantage of Thursday's off-day, if possible.
"I'm aware of that, but at the same time, you want to just be proactive," Gibson said. "He's getting older. I was just talking to [head trainer] Ken [Crenshaw], and you want to plan out.
"If you give him today off and if we get by and win the game without him getting in there, and he gets tomorrow off, now you've given him two days and you've accomplished [something], as far as looking at a longevity factor."
Anderson could get first career start Sunday
MILWAUKEE -- Chase Anderson, called up earlier this week from Double-A Mobile, could get his first Major League start on Sunday against the White Sox.
"I'm leaning towards him starting on Sunday," D-backs manager Kirk Gibson said before Wednesday's game.
Anderson, named the organization's Pitcher of the Month for April, had not allowed a run in 20 consecutive innings covering his last three starts prior to being called up to the Majors for the first time.
The right-hander was 4-2 with a 0.69 ERA in 39 innings with Mobile. Gibson said that right-hander Trevor Cahill, who was moved to the bullpen in mid-April after four starts, would remain a reliever.
Cahill, 8-10 with a 3.99 ERA last season in 26 games, including 25 starts, is 1-5 this season with a 6.59 ERA, but he has not allowed a run in five of his last six appearances.
"We're going to leave him in the bullpen right now, that's what we talked about," Gibson said. "He had one hiccup. He's throwing the ball better and then get got sick. Then he threw OK in his first game here. We'd like to see him repeat that, be consistent with it. That's what we need. I haven't really talked to him in a while about it, but I think he's kind of enjoyed the switch. It's different for him and he's responded well to it."
