Blue Jays placed RHP Casey Janssen on the 15-day disabled list, retroactive to March 29, with a left abdominal/lower back strain. It's not clear when Janssen suffered the injury or how long he'll be sidelined. The reliever also dealt with shoulder issues this spring, as he was limited to just three spring outings. The Blue Jays will presumably use Sergio Santos in the ninth inning while Janssen is out, though Steve Delabar could also get a look.
