He had raised concerns about his role with the club after the first few weeks of the season.
Wolf, who was in camp on a minor-league deal after missing last season following Tommy John surgery, told reporters Tuesday that he was told he had a spot. But Wolf's concern was whether he would be with the team beyond the first 45 days with two members of Seattle's rotation -- Hisashi Iwakuma and Taijuan Walker -- not expected to be ready until late April.
Wolf said he was asked to sign a waiver allowing the team to release him within the first 45 days without paying his full season salary. He declined to do so.
Wolf made five starts this spring and had a 4.26 ERA in 19 innings.
