Mosser made 25 starts in 2025, split between Double-A and Triple-A. Mosser posted a 6-9 record with a 5.20 ERA and 127 Ks in 124 2\/3 innings. He will be looking to fill a long-reliever and spot-starter role in Spring Training, but he’ll have plenty of competition.<\/p>\n

The Mariners are set in their rotation and have one of the best closers in baseball in Andres Munoz<\/a>. They have a potentially lethal left-handed combination<\/a> in Gabe Speier and Jose Ferrer. But, they have shown some concern for the right side of the bullpen, particularly in middle and long relief.<\/p>\n Having already added pitchers of similar status like Cooper Criswell and Dane Dunning<\/a>, there’s a somewhat undetermined role that the Mariners front office is looking to fill. It could be a full-time spot, or it could be a shuttle back-and-forth to Tacoma, and only being called up when needed. While the early favorite for that spot is likely Dunning, the team has given itself plenty of options with these low-risk signings.<\/p>\n More Seattle Mariners News & OpinionsMariners will play 13 national TV games during the 2026 regular season<\/a>Mariners closer Andres Munoz should be set for a career year in 2026<\/a>MLB Writer says Mariners fans shouldn’t worry about recent prospect ranking<\/a>Mariners legend Felix Hernandez gets closer to Cooperstown, but no call yet<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"Earlier this month, the Seattle Mariners signed 29-year-old right-handed pitcher Gabe Mosser, who had previously pitched for the…\n","protected":false},"author":2,"featured_media":432244,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[435],"tags":[49,48,462,82],"class_list":["post-432243","post","type-post","status-publish","format-standard","has-post-thumbnail","category-mlb","tag-ca","tag-canada","tag-mlb","tag-sports"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/432243","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/comments?post=432243"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/432243\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media\/432244"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media?parent=432243"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/categories?post=432243"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/tags?post=432243"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
