Jhoulys Chacin, Jeff Francis, Jorge De La Rosa and Juan Nicasio appear to be set in the Rockies' rotation, and Drew Pomeranz will likely join them if the Rockies don't acquire anyone from outside the organization. Chacin and De La Rosa have both recently missed spring training starts with what appear to be minor injuries.
Garland missed all of the 2012 season and much of the 2011 season with shoulder problems. He pitched 12 innings for the Mariners this spring, posting a 2.25 ERA while striking out four batters and walking five.
Jon Morosi of FOX Sports writes that Garland will also likely draw interest from the Padres and Rangers. Both teams appear to be in the market for starting pitching.
