"We're going to keep an eye on Delabar, too, he's hanging a little bit," manager John Gibbons said. "Nothing unusual, just there's been a lot of work."
In other news Saturday, Delabar was one of five relievers from the American League to receive a nomination for the Final Vote. The ballot will give fans an opportunity to decide which pitcher is deserving for the last spot on the American League All-Star team.
The 29-year-old righty has thrown 40 innings, which ranks 13th in the AL this season.
Delabar, who is 5-1 with a 1.58 ERA, 1.25 WHIP, a .193 average against and 57 strikeouts, has been one of the stabilizing forces in a solid Toronto bullpen.
Reliever Neil Wagner was also unavailable after throwing 39 pitches in Thursday's game against the Tigers.
