The 2009 calendar year was one of highs and lows for the Orioles.

As 2010 begins, the Orioles have questions galore, but the to-do list for president Andy MacPhail is much less cumbersome on this New Year’s Day.

MacPhail must add a corner infielder, a left-handed reliever and probably another starting pitcher. But he’s found his starting outfield plus a talented fourth outfielder, three young, talented, major league-ready pitchers and a veteran to lead the rotation.

The Orioles have a wealth of young pitching with left-hander Brian Matusz and right-handers Chris Tillman and Jake Arrieta, the only one of the three who has yet to debut with Baltimore.

But the Orioles also found a surprise rotation standout, right-handed rookie Brad Bergesen.
