SEATTLE -- After veteran right-hander Hisashi Iwakuma had a rough two-inning rehab start in Triple-A Tacoma on Monday night, the Mariners will have him make at least one more Minor League start instead of rejoining the rotation on Saturday as originally planned.
Manager Scott Servais has already announced that Felix Hernandez will return from the disabled list and pitch Friday's series opener with the Astros, but Saturday's starter now is yet to be decided as the club debates whether to go with rookie Sam Gaviglio or veteran Christian Bergman.
Iwakuma's next outing hasn't been determined yet, but he'll be given an extra day or two between starts, which likely means taking the mound again on Saturday or Sunday after allowing four hits and four runs with a pair of walks in a 49-pitch outing against Salt Lake on Monday.
