Left-hander J.A. Happ was recently shut down for the season after being diagnosed with a fractured right foot. That injury moved Aaron Laffey back into the rotation, and means the six-man rotation won't be unveiled until late September.
The Blue Jays are set to play a doubleheader against the Orioles on Sept. 24, which will create the need for an additional starter, and it's likely that they'll keep the rotation intact from that point on.
"Right now, [Chad] Jenkins is a guy that we've talked about being the guy that would get one of those games," manager John Farrell said of the doubleheader. "Then, going forward from there, we run it out consecutively, so I think coming out of that doubleheader, we'll take a look. He may continue on after that. Might be one more start after that. That's who, right now, we're looking at."
Jenkins entered this season as one of the club's top pitching prospects, but suffered through a somewhat disappointing year with Double-A Hampshire. He began to turn things around in late July and eventually earned a promotion in August.
Since Aug. 7, Jenkins has appeared in nine games out of the bullpen. He is 0-1 with a 4.24 ERA while striking out eight in 17 innings of work. Jenkins would have an outside chance of competing for a starting job next spring and the club would like to get a look at him in that role before the end of the year.
With an off-day looming on Monday, the decision to stick with five starters for the time being won't impact the Blue Jays' stance on left-hander Ricky Romero for at least another two turns through the rotation. Toronto has planned on giving Romero an additional day of rest for each remaining start and will still be able to do that until Sept. 23 due to the upcoming off-day.
