Every five days, the Jays figured to be in an unenviable position that would result in uncompetitive starts and too much work for the bullpen.

In nine outings on regular four days’ rest, Gausman is 5-2 with a 5.12 ERA. “It was a conversation, obviously, taking a look at how many starts are going to be had before the all-star break,” Gausman said recently about the rotation. So it’s not like anyone has circled a date on the calendar.”A four-man rotation won’t be sustainable for much longer.
