The first step was running on the field, and Rasmus will slowly increase the intensity of those workouts before he goes on a rehab assignment. The Blue Jays won't commit to a timeframe for his return, but he'll likely be out at least another week.
"He was out there running and shagging in early BP," Blue Jays manager John Gibbons said. "We'll see, we'll see in the next few days what happens."
When Rasmus does make his return, the Blue Jays will be faced with a difficult roster decision. Toronto is carrying three catchers, and Gibbons likes this configuration because it allows veteran Dioner Navarro to start at designated hitter vs. left-handed pitching.
That leaves either Anthony Gose or Kevin Pillar as the logical options for a demotion. Both players have been playing well over the past couple of weeks, but offer very different skill sets. Gose is the superior defender in center field and provides lethal speed off the bench. The right-handed hitting Pillar could provide Rasmus with a bit of a break when there's a lefty on the mound.
The Blue Jays will likely have to make that decision in a week or so, and at least for now, aren't going to tip their hand.
"We'll worry about that when we get there," is all Gibbons would say on the matter.
