Wainwright (groin) was activated Saturday and will make his season debut against the Tigers.
A groin strain sent Wainwright to the injured list to begin the season and will wind up costing him over a month. His 6.23 ERA and 1.54 WHIP in three rehab outings hardly inspire confidence, though those marks do come with a 13:2 K:BB. The 41-year-old righty maintained a respectable 3.71 ERA last season despite the fact that his strikeout rate dropped to 17.8 percent. Guillermo Zuniga was optioned in a corresponding move.
