Chicago Cubs right-hander Marcus Stroman was placed on the 15-day injured list with right hip inflammation, the team announced Wednesday.
The move is retroactive to Tuesday.
In a corresponding move, the Cubs added right-handed pitcher Jose Cuas, who was acquired Monday in a trade with the Kansas City Royals, to the 26-man roster.
Stroman, 32, is coming off a shaky performance Monday, when he was rocked for six runs in three innings in a 6-5 loss to the Cincinnati Reds. It was the third straight start in which he failed to get out of the fourth inning, a span in which he has allowed 17 runs in 10 innings.
