McCarthy placed on DL with shoulder injury

CHICAGO -- Brandon McCarthy has been down this road before, so after it was announced that the right-hander was going on the 15-day disabled list with shoulder inflammation, he was ready for the media as they approached his locker in the visitors' clubhouse.

"That's cool," he told his teammates. "I've got this one memorized."

Randall Delgado was recalled from Triple-A Reno to take McCarthy's spot on the roster.

This marked the fifth consecutive year that McCarthy has spent some time on the disabled list with a shoulder issue. So, on the one hand, McCarthy knows what to expect with the injury. But on the other, it certainly is frustrating that it continues to happen.

"You take away a lot of the unknown," McCarthy said. "I know what the recovery is. I know how long it takes. I know what I'm feeling for. That makes it a little easier, when you're not worried. I kind of know the road, at least. That helps some. But the fact that I can't still figure out how to get around it, or what it is, that's kind of the difficult part."

McCarthy, 29, lasted just 2 2/3 innings in his last outing on Thursday in Texas, bringing his season mark to 2-4 with a 5.00 ERA in 11 starts. Prior to Thursday, McCarthy had a run of three starts in which he went 2-0 with a 0.38 ERA, including a career-high 18-inning scoreless streak.

How long McCarthy will be out remains to be seen. He is scheduled to return to Phoenix on Sunday and will have an MRI taken on Monday, at which time he will visit with D-backs team physician, Michael Lee.

In the past, McCarthy has missed up to three months with the injury, but he is hopeful that it won't be as long this time.

"What we've gone with the last two years is we wait until there are no symptoms and then take another two days after that and then start throwing again," McCarthy said. "The whole problem with all of this is, that would be great, then I'd be out for 10 days and then I could go. But if you take 10 days off, you have to throw for another couple of weeks and build back up. And then a rehab start or two is another 10 days. Time adds up that way."

Williams, Samardzija exchange words on field

CHICAGO -- D-backs third-base coach Matt Williams was impressed with the way Cubs pitcher Jeff Samardzija threw the ball Saturday night, but the former All-Star was not pleased with the way Samardzija handled himself.

Williams and Samardzija appeared to have words as Williams jogged off the field following the third out of an inning.

According to Williams, Samardzija yelled at him, "What are you looking at?"

Williams said he replied, "I'm not looking at you."

"I have no idea," Williams said when asked why Samardzija would say that to him. "I didn't say a word to the man and I don't have any respect for that. I have no respect for him showing somebody up on the field."

Delgado called up, but Skaggs could get start

CHICAGO -- Randall Delgado was recalled from Triple-A Reno to take injured right-hander Brandon McCarthy's place on the D-backs' roster, but who will take McCarthy's spot in the rotation remains to be seen.

D-backs manager Kirk Gibson did not commit to Delgado starting in McCarthy's place on Tuesday, and there are indications that the club could recall left-hander Tyler Skaggs to make that start.

"He'll be an option," Gibson said of Skaggs. "We'll get through these next couple of days. We may keep Delgado. It just depends on what goes on."

By bringing up Delgado now, the D-backs give themselves an extra arm in the bullpen through Monday. The club could then recall Skaggs to start Tuesday.

Skaggs was impressive last Monday when he started against the Rangers at Chase Field. Skaggs, ranked as the team's No. 1 prospect by MLB.com, tossed six shutout innings and allowed just three hits.

Delgado, who was acquired during the offseason trade that sent Justin Upton to Atlanta, got off to a rough start in Reno, but has pitched better of late.

Chavez has minor tear of oblique muscle

CHICAGO -- An MRI taken of Eric Chavez's side showed a minor tear of his right oblique muscle.

Chavez sustained the injury while taking a swing in the first inning of Thursday's game against the Rangers.

The team placed Chavez on the 15-day disabled list Friday, and it is uncertain how long he will be out.

"The best-case scenario would probably be 15 days to three weeks," D-backs manager Kirk Gibson said. "It's hard to tell. I've had those where you get them and you go down and you can't breathe. It wasn't like that, but it was definitely there."

D-backs shortstop Willie Bloomquist suffered an oblique tear towards the end of Spring Training and was activated for the first time on Friday.

"It doesn't look like it's as bad as Willie's," Gibson said.

Chavez was a big part of the Arizona offense hitting .325 with seven homers and 25 RBIs before the injury.

Snake bites

• Second baseman Aaron Hill took 40 swings hitting off a tee on Saturday. Hill is recovering from a fracture in his left hand. The club is hopeful he'll be able to hit off live pitching by next weekend.

• Right-hander Daniel Hudson, who is recovering from Tommy John surgery, is scheduled to make his first rehab start on Tuesday with Double-A Mobile.

If all goes well, Hudson will pitch for Mobile again June 10. Given that schedule, the quickest Hudson could return would be sometime in mid-June.

• Closer J.J. Putz, who is on the disabled list with a strained right elbow, is scheduled to throw his first flat-ground sessions this week and possibly off a mound next weekend.

• Triple-A Reno shortstop Chris Owings has 84 hits this year, more than any other batter in pro ball. The Tigers' Miguel Cabrera is second with 81. Owings has hit in 19 straight games.

• Double-A Mobile right-hander Archie Bradley has a 1.01 ERA combined between Mobile and Class A Visalia, second-best in the Minors. He's 4-1 with a 0.79 ERA in six starts for Mobile. His 80 strikeouts tie him for second in the Minors.
