PHOENIX -- D-backs reliever Matt Reynolds never had arm trouble before, so when his left elbow started feeling achy he did not think much of it.
"I had been getting some treatment on it," Reynolds said. "It felt a little achy and was getting some treatment and felt it was almost out of there, and then it started coming back a little bit."
As it turned out, Reynolds had a slight tear of his ulnar collateral ligament, but opinions from team physician Michael Lee and Dr. James Andrews both told Reynolds that he could try and rehab the elbow rather than have Tommy John surgery.
"From what I understand, it's in a good spot," Reynolds said. "And hopefully I can just wait around, rehab it for a little while and be good as new."
Reynolds said he will continue to rest and strengthen the elbow for four to six weeks.
"Just trying to take it one day at a time," Reynolds said. "Obviously, it wasn't the best news, but it wasn't the worst, either."
Kennedy drops appeal, begins serving suspension
PHOENIX -- D-backs right-hander Ian Kennedy dropped his appeal and began serving his 10-game suspension Monday night.
Kennedy received the suspension for his part in the brawl between the D-backs and Dodgers last week in Los Angeles.
Kennedy had appealed the decision, which allowed him to make his scheduled start Sunday against the Padres. By choosing to serve his suspension now, Kennedy minimized the effect of his absence. That's because the D-backs have a pair of off-days over the next week that will allow them to get by with just four starters.
"Doing it this way was better for the team," Kennedy said. "I didn't know when the hearing was, I didn't have a date or anything, so I wanted to put it behind me. Every time I walked by, it seemed like there was another question being asked about it and I didn't want my teammates to be distracted with it, either."
Due to the injury to Brandon McCarthy, the team will still have to call up a Minor Leaguer to start Tuesday and that will be Randall Delgado.
Kennedy is eligible to start June 29 against the Braves in Atlanta. Until then Kennedy is allowed to be in uniform during batting practice, but can't be in the dugout during his suspension.
"I'll just throw extra bullpens and use it as work time to get better," Kennedy said.
Whether Delgado will also make starts on June 23 and 28 likely depends on how he pitches. Left-hander Tyler Skaggs, who was sent down last Monday, could be recalled as soon as Thursday if the team wants him to make the starts instead.
Gibson tabs Delgado to make Tuesday's start
PHOENIX -- Right-hander Randall Delgado will get another chance to make a lasting impression when he gets the start Tuesday against the Marlins.
Delgado, who lost out in his bid to win the No. 5 spot in the rotation during Spring Training, was called up briefly earlier this month and made one relief appearance before being sent back to Triple-A Reno.
"Delgado was up here and got his feet wet this year, went back down worked on some things, threw a good game, [had] better command and he's the guy," D-backs manager Kirk Gibson said.
Delgado will take the place of Tyler Skaggs in the rotation. Skaggs was sent to Reno last Monday when the team added Charles Brewer to bolster a tired bullpen.
Josh Collmenter was thought to be the frontrunner to make the start, but Gibson decided he was more valuable in his long-relief role.
"He's really good at what he does, you could say arguably as good as there is," Gibson said of Collmenter. "You get into an extra-inning game, you put Collmenter in there and he's won three of them for us. He's done his job. I think, ultimately, if you moved him into a starter's role, then you had to take someone to fill his role and then you're filling two roles and here we're just filling one."
Gibson would not commit to Delgado past Tuesday's start. Due to the rule that says an optioned player must remain in the Minor Leagues for 10 days after being sent down, Skaggs is not able to be recalled until Thursday at the earliest.
Eaton progressing well in extended spring training
PHOENIX -- D-backs outfielder Adam Eaton served as the designated hitter in extended spring training games last weekend as he continues to work his way back from an elbow injury.
Eaton was less than a week away from returning to the big leagues before suffering a setback in his rehab in late May. Eaton felt a little discomfort in his elbow while making a throw and was shut down again. He is back to playing catch and has not felt any additional pain.
"Everything feels good," Eaton said. "Feels back to where I was. It only hurt that one throw and I felt great before that."
It is possible that if all continues to go well that Eaton could go back out on a rehab assignment and play in the outfield again in another two weeks.
"I haven't really looked too far ahead," Eaton said. "It's coming along, though."
• Right-hander Brandon McCarthy will likely throw a flat-ground bullpen session Tuesday as he continues to work his way back from shoulder inflammation.
"It's the normal super uninteresting progression where it's just every day just kind of gauge it and start throwing and building back up strength and just kind of doing rehab work," said McCarthy, who was placed on the disabled list June 1.
McCarthy believes he is close to beginning to throw off the mound in a bullpen session.
"Some point this week, probably," he said.
McCarthy has not suffered any side effects from medication he's taking after suffering a seizure a couple of weeks ago. The only lingering problem from the seizure is that McCarthy still has not recovered feeling in half of his tongue.
• Closer J.J. Putz threw a bullpen session Monday and could be close to starting an injury rehab assignment.
"I feel great," Putz said. "Everything is coming out good."
D-backs manager Kirk Gibson said Putz might throw a live batting practice session before starting a rehab assignment.
• Gibson said several times during the series with the Padres that resulted in a sweep that he was unhappy with the approach of his hitters.
"I probably should have given more credit to the Padres' pitchers," Gibson said. "They really pounded the zone, got ahead and then made good quality pitches on the edges."
