CHICAGO -- Cubs pitcher Jake Arrieta, rehabbing from tightness in his right shoulder, gave up one run and took the loss in his first Minor League rehab start for Double-A Tennessee on Saturday.
The Smokies lost, 5-0, in a game shortened because of rain. Arrieta walked a batter, and the run scored on a wild pitch. He struck out three and threw 42 pitches, 28 strikes, in three innings.
Cubs manager Rick Renteria said he received good reports on Arrieta, who did not pitch in any Cactus League games this spring.
There is no timetable for Arrieta's return, and he was expected to make at least two more Minor League starts.
