The Blue Jays have claimed lefty Brad Mills off waivers from the Athletics, reports Ken Rosenthal of FOX Sports (via Twitter). Mills was designated for assignment on July 7 to make room for trade acquisition Jason Hammel.
In his first MLB action since 2012, Mills allowed eight earned runs in 16 1/3 frames while striking out 14 batters and issuing seven free passes. Before his acquisition by Oakland, Mills had impressed at Triple-A for the Brewers, compiling 75 innings of 1.56 ERA ball with 9.2 K/9 against 2.2 BB/9.
Toronto does not have rotation space for the out-of-options Mills unless it sends one of its younger arms (Drew Hutchison or Marcus Stroman) to the pen or the minors or pushes out J.A. Happ (another lefty). The Jays could presumably utilize Mills in a relief role, though the club has enjoyed reasonably effective performances from fellow southpaws Aaron Loup (3.20 ERA) and Brett Cecil (3.68 ERA), the latter of whom is also out of options.
