Aaron Sanchez returned to the 10-day disabled list on Monday, one day after he was activated by the Toronto Blue Jays from the DL.
The Blue Jays recalled right-hander Danny Barnes from Triple-A Buffalo in a corresponding move.
In his first start off the disabled list, Sanchez lasted just one inning Sunday in his return from a blister on his middle finger.
The Blue Jays said the right-hander left because of a split fingernail on his middle finger.
