Morrow, who ended up on the disabled list after leaving his last start June 11 with an oblique strain, has began a light-throwing program, but there is still no timetable for his return.
"He's in a throwing program, but there is a loose framework to it because one, the main goal is just to keep his arm moving," Blue Jays manager John Farrell said. "So there are days he comes in and feels he can reproduce just a throwing motion at 60 and 90 feet. But there are other days he comes in and he might feel a little more tight than others, and he won't throw on that day."
When Morrow increases the intensity of his rehab or starts throwing off a rubber is currently unknown, but Farrell said the fact he has a ball in his hand is positive. The Blue Jays skipper did not speculate on a possible return date, so the club will likely take a cautious approach with the fireballer, slowly easing him back to the mound to prevent a setback.
Morrow was enjoying a career season and was Toronto's best pitcher at the time he sustained the injury. Through 13 starts, the 27-year-old posted a 7-4 record, 3.01 ERA and 1.00 WHIP to go along with 67 strikeouts over 77 2/3 innings.
Perhaps the most impressive part of Morrow's early success was his control, something that perpetually plagued him in years past.
Morrow's walk rate was at a career-low mark, and the 2.78 walks per nine innings he was averaging was the first time he had got that number under 3.00 in his career. At one point, Morrow posted back-to-back starts without issuing a walk after entering the season having walked at least one batter in every start of his career.
Despite missing close to a month, only Jake Peavy and Justin Verlander have more complete games than Morrow's three.
