While saying Wednesday that McGowan is "probably going to start again", Gibbons added that he remains intrigued by what McGowan could possibly bring to a beleaguered bullpen.
Meanwhile, the Blue Jays continue to closely monitor the progress of right-hander Marcus Stroman, who worked six hitless innings for Triple-A Buffalo on Tuesday. Stroman could be a rotation option if McGowan ultimately goes to the bullpen.
"He's on the radar," Gibbons said of Stroman. "We were watching him on the computer. He had it all going on out there."
