Trevor Rosenthal

Tigers reliever Trevor Rosenthal is set to undergo a UCL reconstruction revision.

Fantasy Impact

It's equivalent to the second Tommy John surgery of Rosenthal's career (2017). It's just the latest setback of many for Rosenthal as he attempts to return to a big league mound. Signed to a minor-league deal late in spring training, the 33-year-old was deemed not ready to begin the season and will now miss all of the 2023 campaign and most of next season as well. He hasn't pitched since tossing a 1.90 ERA between the Royals and Padres in the 2020 season.

Detroit Tigers reliever Trevor Rosenthal will not be ready for Opening Day.

Fantasy Impact

The Tigers signed Rosenthal to a minor-league deal on March 4 and manager A.J. Hinch said Opening Day "is not something that's feasible". The Tigers will take their time ramping Rosenthal up, a prudent move considering he hasn't pitched since the 2020 season, largely due to Thoracic Outlet Syndrome. That 2020 season was a dominant one, however, as Rosenthal turned in an eye-popping 1.90 ERA and 41.8% K% across 23 outings between the Royals and Padres, locking down 11 saves in the process. When healthy, Rosenthal has the potential to see save opportunities for the Tigers in 2023.

The Detroit Tigers have signed reliever Trevor Rosenthal to a minor-league deal with an invite to MLB spring training.

Fantasy Impact

The Tigers are taking a flyer on Rosenthal after he missed each of the last two seasons due to injuries. Rosenthal actually briefly pitched for the Tigers in the 2019 season before exploding in 2020 to the tune of a 1.90 ERA and 41.8% K% across 23 2/3 innings between the Royals and Padres, saving 11 games in the process. Thoracic Outlet Syndrome has been a major hurdle to climb in his return to action as the Tigers take a low-risk flyer on the right-hander.

Trevor Rosenthal was traded from the Giants to the Brewers Tuesday.

Fantasy Impact

Rosenthal was signed in late July by the Giants but has yet to make an appearance this season. He is still on the IL with a left hamstring strain and does not have a timetable currently for his 2022 debut. If Rosenthal can get healthy, he figures to slide into a set-up role with the Brewers.

The Giants agreed to a one-year, $4.5 million deal with Trevor Rosenthal on Monday.

Fantasy Impact

Rosenthal can make an additional $2 million in incentives, but he'll begin the year on the 15-day IL with a left hamstring strain. He's still reportedly weeks away from returning, but he has looked good in bullpen sessions and can run pain-free. He's unlikely to make a fantasy impact this year so those in redraft leagues can ignore him.
