The Diamondbacks will add Kepler (suspension) to their active roster before Thursday's game in St. Louis, Nick Piecoro of the Arizona Republic reports.
Upon completing his 80-game suspension for testing positive for a performance-enhancing substance, Kepler will go directly onto the Diamondbacks' roster. The outfielder slashed .333/.474/.567 with two home runs and a 7:6 BB:K in 10 minor-league games, though much of that production came at the lower levels. Kepler gives the Diamondbacks another option in the corner outfield or at designated hitter against right-handed pitching, though he isn't guaranteed a regular role.
