Orioles Notes: Guthrie, Roberts, Minor Leagues

The Nationals may be generating most of the headlines today, but there's also some news coming from the Beltway's other team.  Here's the latest from the Orioles…

• Jeremy Guthrie is perhaps Baltimore's most attractive trade candidate, but MLB.com's Brittany Ghiroli doesn't think the right-hander will be moved.  "It would take a significant haul on the Orioles' side to give up Guthrie," Ghiroli writes, and she also points out that Guthrie is the only veteran and only innings-eater on the club's pitching staff.  Ghiroli cites the Indians and Rangers among the teams who have shown interest in Guthrie.  
• From that same mailbag item, Ghiroli thinks the Orioles should start looking for a new long-term answer at second base.  Brian Roberts will be 36 when his deal runs out after the 2013 season and the former All-Star is already a question mark due to injuries.  Short-term, however, the O's have no second base prospects ready to step in and Roberts has a no-trade clause in his contract.
• The lack of minor league production from several of the Orioles' top prospects "has to be considered an organizational-wide failure," writes The Baltimore Sun's Jeff Zrebiec.  The development system has been further skewed since "for years, Oriole minor leaguers have been getting promotions because of a desperate need at the big league level, not because they’ve necessarily earned a shot."
