Hisashi Iwakuma again just played flat-ground catch instead of throwing off the bullpen mound Wednesday for his between-game session due to a sore neck, but manager Lloyd McClendon said the right-hander remains on line to start Friday in Kansas City.

Kyle Seager had eight RBIs in the final three games of the recent Safeco Field homestand. The Mariners are 19-6 in games when Seager has had an RBI this season.
