CHICAGO -- Chicago Cubs starting pitcher Tsuyoshi Wada left Friday’s game against the Pittsburgh Pirates in the fourth inning with a mild left calf strain, the club announced.

Wada had just given up a run-scoring double to Jose Tabata allowing the Pirates tie the game 2-2 before he left.

Pitcher Carlos Villanueva took over for Wada and promptly gave up a run scoring hit to Josh Harrison. The Pirates lead 3-2 in the fifth inning as the game is in a rain delay.

Wada is day-to-day, according to the team.
