On the heels of a 96-win season and division title, the Orioles fell short of the 2015 postseason. The O’s were in it until just before the season’s final weekend, but they could not keep pace with the Toronto Blue Jays and New York Yankees. With that disappointment comes some tough decisions in the offseason. Five core players who have been with the club since 2012 or earlier could leave through free agency. Among them is Chris Davis, who led the American League with 47 home runs in 2015.
