According to Scott Mitchell of TSN Sports, the Seattle Mariners have claimed relief pitcher Hagen Danner off of waivers. The 26-year-old made a brief one-inning appearance with Toronto in 2023 and spent the entire 2024 campaign in the minor leagues. Across 34 1/3 innings of relief with Triple-A Buffalo, the right-hander posted a 3.15 ERA and a 1.31 WHIP. He struck out 34 batters while serving up 13 walks. He tallied seven saves. This was similar to the 3.81 ERA and 0.95 WHIP he held across 28 1/3 innings at Triple-A in 2023. Fantasy managers should expect Danner to contend for a spot on the Opening Day roster in Seattle but will likely open the campaign at Triple-A given his lack of big league experience.

The Toronto Blue Jays designated right-handed pitcher Hagen Danner for assignment on Friday to make room on the 40-man roster for left-hander Josh Walker, who the team signed to a big-league deal worth $760,000. The 26-year-old Danner made his major-league debut with Toronto in 2023 but only appeared for one-third of an inning. The former second-round selection in 2017 out of Huntington Beach High School went 3-0 with a 3.06 ERA, 1.27 WHIP, seven saves, 34 strikeouts and 13 walks in 34 1/3 innings over 33 appearances out of the bullpen for Triple-A Buffalo this past season. If Danner clears waivers, he'll likely return to the Blue Jays and open the 2025 regular season back at Buffalo as relief depth for the organization.
