The Tigers optioned De Jesus to Triple-A Toledo on Sunday.
De Jesus has been a decent bullpen option for Detroit this year with a 3.83 ERA, 1.25 WHIP and 39:15 K:BB across 42.1 innings, though he's been a bit shakier over his past six outings with four earned runs allowed. Andrew Sears will take his spot in the bullpen and is poised to work in bulk relief Sunday against the Royals.
