Baltimore Orioles executive vice president Dan Duquette confirmed that the deal with relief pitcher Grant Balfour is off, and the club will try to find another closer.
"The Orioles were disappointed that we couldn't complete a contract with Grant Balfour," Duquette said, according to MASNSports.com. "The reason is the club's not satisfied with the results of the physical exam.
"We would never say never or close the door, but we're turning our attention elsewhere for now to look at some other options to try to staff our team and try to build a contending team for 2014."
Duquette is not permitted to provide specific details of the exam.
"These medical issues, you have to protect confidentiality, and there's not a lot that the team can say publicly," he said. "The only thing I can tell you is the club was not satisfied with the results and we're not going to get into particulars of what the specific club's concerns were."
The Baltimore Sun reported that the Orioles cancelled a news conference Friday to introduce the reliever after team doctors expressed concern with Balfour's right shoulder during his physical.
However, Balfour told the San Francisco Chronicle's Susan Slusser that the MRI results were exactly the same as they were three years ago.
"I'm the All-Star pitcher I was last season," he told the Chronicle. "My shoulder is fine, everything is fine. I'm ready to come out there in the ninth inning, do what I do."
On Tuesday, it was reported that Balfour had agreed to a two-year, $15 million contract with the Orioles that included $500,000 in deferred payments each of the next two seasons.
Balfour has not been placed on the disabled list since 2011. He did have surgery on his right knee last spring, but it was not a problem during the season.
The 35-year-old posted 38 saves and had a 1-3 record with a 2.59 ERA and 72 strikeouts in 62 2/3 innings for the Oakland Athletics in 2013. In the past two seasons for the A's, Balfour had 62 saves in 67 opportunities.
