Snead was optioned to Triple-A Buffalo on Monday.
Snead has spent the past couple weeks in the majors and appeared in five games, giving up three runs (two earned) on five hits with four strikeouts and two walks over six innings. He has a 1.95 ERA, 0.90 WHIP and 43:12 K:BB across 32.1 innings at Triple-A this season, and he's a likely candidate to rejoin the Blue Jays when bullpen help is required down the stretch.
