The Blue Jays assigned Andrews to Triple-A Buffalo after he cleared waivers Sunday, Ben Nicholson-Smith of Sportsnet.ca reports.
Andrews was DFA'd by the Blue Jays on Thursday in order to make room on the 40-man roster for Chad Dallas. Andrews went unclaimed off waivers and will return to Buffalo, where he has a 1.29 ERA, 1.29 WHIP, five saves and a 23:15 K:BB over 21 innings this season.
