Morton (shoulder) was scheduled for a long-toss session Sunday, Alyson Footer of MLB.com reports.
Morton has been making steady, setback-free progress via bullpen sessions over the last several days, and there had even been talk at one point he could be activated to start a game during the ongoing weekend series against the Blue Jays. That possibility was eventually ruled out, but Morton could be close to a return if he continues to build his arm strength up without any issues. The veteran right-hander noted it's a bit of a tightrope walk at the moment, considering that it's necessary at times to up the intensity of the throwing sessions to get an accurate assessment of progress while acknowledging such a strategy also comes with an element of risk.
