The Tigers optioned Sears to Triple-A Toledo on Saturday, Chris McCosky of The Detroit News reports.
Sears will depart the active roster to make room for Justin Verlander (hamstring/hip), who was activated to start Saturday's contest. Sears posted a 2.16 ERA and 1.03 WHIP over 58.1 innings in the minors this season but struggled mightily in the big leagues, allowing 15 earned runs in just 19 frames.
