The Blue Jays optioned Thornton to Triple-A Buffalo on Saturday.

The righty appeared in two games after being recalled Sunday, allowing one hit and striking out one in 1.2 scoreless innings. With a 4.58 ERA in 39.1 innings this season, Thornton has pitched well enough to earn future opportunities with the big-league club. Alek Manoah (back) was activated from the 10-day injured list in a corresponding move Saturday.
