Cubs right-hander Tsuyoshi Wada has moved his minor league rehab assignment to Triple-A Iowa. On Saturday, Wada made the start for the Iowa Cubs, allowing one run on four hits and two walks over four innings.
Wada has been on the disabled list with a shoulder injury since June 28. He hasn't pitched for the Cubs since June 22, but he does own a 3.73 ERA in seven starts this season.
