Consequently, they'll push the limits of their pitching depth.
Lodolo, who left his Aug. 4 start in the second inning because of a left index finger blister that developed suddenly on a breaking ball thrown to the Chicago Cubs' Justin Turner, landed on the 15-day injured list, as expected, Aug. 5.
Reliever Yosver Zulueta was recalled from Triple-A Louisville to join the bullpen and take Lodolo's place on the roster.
Nick Nick Martinez, who got seven outs in relief of Lodolo Aug. 4, likely will take the lefty Lodolo's spot in the rotation for his next turn, probably Aug. 9 in Pittsburgh.
If there's a silver lining to the move for the Reds, it's that they might be better equipped to weather such a pitching storm than they were a week ago, after acquiring right-hander Zack Littell from Tampa Bay at the trade deadline. Little was scheduled to start against the Cubs Aug. 5.
Lodolo, who has been the workhorse of the Reds' pitching staff this season, lands on the IL for the first time this season. He spent two weeks on the IL last season with a similar blister problem.
