Mariners Claim Hagen Danner

The Mariners announced that they have claimed right-hander Hagen Danner off waivers from the Blue Jays. The latter club had designated him for assignment last month. DFA limbo normally only lasts a week but that clock is paused during the holidays. Seattle’s 40-man roster count is now 39.

Danner, 26, has a fairly limited track record as a pitcher. That’s due to his unusual trajectory, as well as some injuries. He was drafted by the Jays as a catcher in 2017 but struggled at the plate and moved to the mound in recent years. His first professional season as a pitcher was 2021, a year in which he tossed 35 2/3 innings at the High-A level, allowing 2.02 earned runs per nine. He struck out 29.4% of batters faced while limiting walks to an 8.4% clip.

Although he had only been on the mound for that one season as a minor leaguer, he was already Rule 5 eligible on account of the years he spent behind the plate. But the Jays didn’t want him to get away at that time and gave him a spot on the 40-man.

He spent most of 2022 on the injured list, only making four Double-A appearances. He was healthy again in 2023, tossing 39 1/3 innings across multiple levels, with a 3.66 ERA, 35.7% strikeout rate and 7% walk rate. He also made his major league debut, although he only tossed a third of an inning before an oblique strain sent him to the IL for about six weeks to finish the year. In 2024, he spent another two months on the minor league injured list but managed to toss 35 1/3 innings on the year with a 3.06 ERA, 24.2% strikeout rate and 8.7% walk rate.

Perhaps that big drop in his strikeout rate prompted the Jays to move on, though the Mariners are intrigued enough to give him a shot. Danner is still a fairly unknown quantity at this point, with barely 100 professional innings under his belt, but he still has an option year left. Seattle can get a close-up look at him and see how things play out. He can serve as optionable depth for one more year and, if things break right, be cheaply retained into the future since he has just a handful of service days.
