The Chicago Cubs' Tsuyoshi Wada surrendered five runs in six innings in his sixth rehab start on Saturday as he works his way back from shoulder injury.

On the disabled list due to left-shoulder inflammation since June, Wada allowed nine hits, struck out four and walked two for Triple-A Iowa. His team handed him an 11-run lead by the top of the third but the southpaw gave up three runs in the bottom of the inning and two more in the fifth in his 87-pitch outing.

"I don't think my pitches moved and on top of that my control wasn't good at all either," said Wada, who did pick up a win in the game. "I haven't got anything to say because the results aren't coming along at the moment. All I can do is to try to deliver them."

Wada started his rehab games with Iowa on July 6 and can only pitch in the minors for 30 days while on the disabled list under regulations.

Wada has started seven games for the big league club with a 1-1 record and a 3.73 ERA.
