It seems as though the shoulder fatigue southpaw Sean Marshall has been battling lately has finally become too much to bear.
On Wednesday, the Reds placed Marshall on the 15-day disabled list due to shoulder tendinitis.
The move was announced just prior to Cincinnati's series finale against the Cardinals.
Logan Ondrusek will take Marshall's spot on the roster after beginning the season in Double-A Pensacola. Ondrusek will be in uniform this afternoon for the matinee affair and is available to pitch.
Marshall has appeared in just one of the club's eight games in 2013. Dusty Baker was taking a cautious approach with Marshall to let his 30-year-old reliever rest, but Marshall's condition has apparently failed to get significantly better.
Ondrusek appeared in three games for the Blue Wahoos and allowed no runs, one hit, and no walks in 2.1 innings pitched.
Ondrusek was 5-2 with a 3.46 ERA in 63 appearances with the Reds a season ago.
