The highlight of the Baltimore Orioles' offseason was supposed to take place Friday morning, when the club introduced new closer Grant Balfour.

But Balfour's two-year, $15 million deal with the Orioles is in major jeopardy, after team doctors expressed concern with Balfour's right shoulder during his physical, according to sources.

The 11th-hour snag has forced not only the cancellation of the Friday's press conference but also the Orioles' front office to consider its next move with Balfour, whom the club agreed to terms with on Tuesday. If the deal with Balfour falls through -- a real possibility, according to sources -- they must reset their chase for a closer in a dwindling free-agent market.

Balfour, 35, converted 62 of 67 save opportunities for the A's over the past two seasons, but he missed 2005 and 2006 after elbow and shoulder surgeries.
