Blue Jays placed RHP Josh Johnson on the 15-day disabled list, retroactive to April 29, with a triceps injury. An MRI taken earlier this week on Johnson's throwing arm showed no structural damage, but the Jays are going to play it safe. Johnson has posted an ugly 6.86 ERA, 1.88 WHIP and 19/9 K/BB ratio in 19 2/3 innings this season. Maybe the rest will wind up doing him some good.
