The Tigers activated the high-strikeout right-hander after Thursday's game, bringing their bullpen just about back to full strength.
The move had been expected once Marte came out of Monday's rehab appearance for Triple-A Toledo feeling fine, having tossed three scoreless innings with one hit with two strikeouts. Detroit delayed the move only to rest him long enough to be able to pitch once they finally activated him.
Marte pitched in four games for Detroit last year as a September callup, allowing one run on six hits with three strikeouts over 3 2/3 innings. His Spring Training performance, however, more closely resembled last year's at Double-A Erie, where he struck out 68 over 53 innings with a 1.70 ERA.
To make room on the 25-man roster, the Tigers optioned right-hander Luke Putkonen to Toledo. The 26-year-old gave up seven runs on 14 hits over 7 1/3 innings with five walks and six strikeouts.
