PHOENIX -- Jarrod Dyson knew that he was risking further injury if he continued to try to come back this year, but the D-backs outfielder was not ready to give up.

However, Dyson re-injured his lower core, the same issue that he had last year, and will undergo season-ending surgery next week.

PHOENIX -- Jarrod Dyson knew that he was risking further injury if he continued to try to come back this year, but the D-backs outfielder was not ready to give up.

However, Dyson re-injured his lower core, the same issue that he had last year, and will undergo season-ending surgery next week.

Last year, Dyson had double hernia surgery. But this time, it will be his right abductor muscle that will be the focus with the same surgeon, Dr. Bill Meyers, performing the operation.

Dyson was placed on the disabled list July 5 with a strained right groin. He rehabbed the injury and was on a rehab assignment last weekend with Triple-A Reno when he started to experience problems again.

"I was taking a chance," Dyson said. "It was either hit or miss. I tried to do all the right things, and still came up short. It bugs me a lot because I worked so hard trying to get back and I felt like I was so close, and when I tried to play on it, I felt some discomfort, but I kept going on it."

Dyson's right adductor area was filled with fluid and it continued to get tight. He eventually realized that even if he did come back, he would not be able to contribute much because of the injury.

"I had to make that decision, and it's a tough decision," Dyson said. "Because when you make that decision, you feel like you let the team down a lot."

D-backs manager Torey Lovullo said Dyson does not have to worry about that.

"Jarrod was trying to gut it out and get back here as fast as he possibly could," Lovullo said. "This is a very tough baseball player. He wanted to join this pennant race at any cost. [The risk] was outlined to him, but he was going to press on as far as he could."

New addition
With Dyson done for the year, the D-backs acquired infielder/outfielder Patrick Kivlehan from the Mets and called him up Thursday.

Kivlehan, 28, began the year in Triple-A for the Reds before being released on May 1. He signed with New York, where he spent the rest of the season with Triple-A Las Vegas.

Kivlehan said when he did not receive a callup from the Mets after Las Vegas' season came to an end, he packed his bags and returned to his home in New Jersey.

As Kivlehan was unpacking his suitcase, he got the call that he was being traded to Arizona.

Lovullo said Kivlehan will give the D-backs an additional right-handed bat off the bench to counter when teams go to a lefty reliever.

"Excited to have him on-board," Lovullo said. "He comes to us as a guy that's extremely athletic, he's got a lot of pop in the bat, can run the bases, can play corner outfield. We just felt like in the absence of Jarrod it would be a good situation to get this type of guy in here and impact the game."
