Noesi started the season in the Mariners rotation but was optioned to Tacoma in early July after beginning the year 2-11 with a 5.77 ERA. The right-hander worked twice out of the bullpen after being recalled and the plan was for him to make at least two starts before the end of the season.
"You don't rule out a chance of another start, just because you never know how it's going to play out with everybody else," manager Eric Wedge said. "We'll use him mainly for length in the bullpen and he'll get some other opportunities to pitch."
Wedge said he still believes Noesi has a good arsenal of pitches, but needs to improve his presence on the mound.
"It could be a number of different things, only he really knows," Wedge said. "If you talk about the intangibles that you need to have up here when it comes to your focus or your execution of pitches or your concentration or your work in between starts. Whatever it may be, there's a number of different things that go in to being a Major League Baseball player and being a Major League starting pitcher."
Blake Beavan will take Noesi's spot in the rotation and will start on Saturday. Jason Vargas, who was originally scheduled to take the mound Saturday, will be bumped to Sunday.
