Borucki was optioned to Triple-A Buffalo on Tuesday.
EDGE Analysis
Borucki made four appearances after rejoining the Toronto bullpen Sept. 13, allowing two runs on five hits and two walks across 4.1 innings. The southpaw has not pitched since serving a two-game suspension last Friday and Saturday for intentionally hitting Tampa Bay's Kevin Kiermaier. He'll return to Buffalo for the time being but figures to be a top candidate for another call-up should Toronto become in need of another relief arm. Cavan Biggio (neck/back/elbow) was activated from the injured list to take Borucki's spot on the 28-man roster.
