The Orioles lost World Series to NY Mets in 1969 and to Pittsburgh Pirates

But just in case this is a trick question perhaps a little more history is in order.
The original AL franchise in Baltimore (1901,1902) was also named Orioles
before relocating to NYC in 1903 as the Highlanders before being renamed
as the Yankees in 1913. Since winning their first WS title in 1923, the
Yankees have won 27 in total and lost 13.
