Latos was outrighted to Triple-A Buffalo on Monday, Arden Zwelling of Sportsnet reports.
Latos went unclaimed off waivers after the Blue Jays designated him for assignment following three underwhelming starts with the big club, during which he compiled a 6.60 ERA and 1.80 WHIP over 15 innings. The 29-year-old will continue to provide the Blue Jays with starting depth in the high minors, but his days as a reliable rotation option in the big leagues could be over.
