Mayza was placed on the 10-day injured list with left elbow inflammation Saturday.
Mayza tossed a scoreless inning against Cleveland on Thursday to earn his 12th hold of the season. However, he'll spend some time on the shelf due to his elbow injury. The Blue Jays reportedly aren't too concerned about the issue, and they're hopeful Mayza will return after a brief absence, Scott Mitchell of TSN.ca reports. Right-hander Patrick Murphy and left-hander Kirby Snead were among the pitchers who were recalled to take his place in the bullpen.
