Chicago Cubs lefty Tsuyoshi Wada, who is on the disabled list with inflammation in his left shoulder, gave up two runs in the second game of a minor league double header for Triple-A Iowa against Omaha on Saturday.

Wada had his major league rehab assignment transferred to Iowa from Double-A Tennessee prior to the second game, according to the Iowa Cubs official website.

He got the start in the nightcap and allowed two runs, one earned, on four hits and two walks over 4.0 innings. He did not record a strikeout.

It was his second rehab start after going on the DL. Wada threw 71 pitches, 10 more than his previous outing.

Making his season debut on May 20 after returning from a left-thigh injury, Wada has started seven major league games with a 1-1 record and a 3.73 ERA.
