The Blue Jays designated Martin for assignment Friday.

Martin has spent time with the Royals, Orioles and Blue Jays' organizations this season and owns a .280/.408/.415 slash line with eight homers, 32 RBI, 52 runs scored, 39 stolen bases and a 47:71 BB:K across 294 plate appearances at Double-A and Triple-A.
