2025 Fantasy Outlook
Tonkin started the 2024 regular season on the Twins' roster, then spent stints with the Mets and Yankees before finishing the year back in Minnesota after being claimed off waivers in late August. At this stage of his career (age 35), he has below average velocity, but limits hard contact (79th percentile Hard-Hit% per Baseball Savant). He's struggled to find a steady role in a major league bullpen and will need to win a spot in spring training. Read Past Outlooks
Signed a one-year, $1 million contract with the Twins in November of 2024.
Struggles when given save chance
PMinnesota Twins
August 3, 2025
Tonkin entered the ninth inning of Sunday's win at Cleveland in a save situation but couldn't hold a three-run lead. He allowed two runs on two hits and a walk over one-third of an inning before being pulled for Erasmo Ramirez, who recorded the final two outs for the save.
Analysis
Tonkin was given the team's first save chance after the Twins traded their top five relievers at the trade deadline, but he struggled and may have lost his shot to become the closer. Still, it looks like manager Rocco Baldelli may use a committee to close games the rest of the season, and Tonkin could still be part of the mix.

* Exit Velocity, Barrels/BBE %, Balls Hit 95+ MPH %, and Spin Rate are benchmarked against 2019 data (min 30 IP). See here for more exit velocity/barrels stats plus an explanation of current limitations with that data set.

Past Fantasy Outlooks
2017
2016
2015
2014
Tonkin finally became a regular in the Minnesota bullpen last season after dominating at Triple-A and failing to stick in the majors the previous two years. Unfortunately, he struggled with the long ball as he allowed 12 home runs and had an ugly 5.02 ERA. However, there are some encouraging signs as he had a 10.1 K/9 and his long ball problems may have been due to a 16.0 percent HR/FB. He'll need to improve against left-handed batters as he allowed a 1.061 OPS to lefties, but Tonkin will attempt to stay in the majors and win a bullpen role again this spring.
Tonkin had another dominant season at Triple-A, but hasn't been able to find a consistent role in the majors. Tonkin had 46:5 K:BB ratio in 41 innings at Triple-A Rochester, but was up-and-down from the minors last season. His 94.3 mph average fastball resulted in a decent 7.3 K/9 in the majors but he was too wild with 3.5 BB/9. Tonkin should get every chance to win a bullpen role this spring and could find a high-profile setup role due to his velocity if he can reduce his free passes.
Tonkin has a chance to win a setup role this spring after a strong season at Triple-A and reassuring September callup. He struggled when called up to the majors in April and May (5.84 ERA and 9:6 K:BB ratio), but thrived at Triple-A with a 2.80 ERA and 9.2 K/9. When back in the majors in September he improved with a 2.70 ERA and seven strikeouts in seven innings with no walks. Tonkin features a mid-90s fastball that would be welcomed in a bullpen that has lacked velocity. He's also shown good control in the minors. Tonkin could quickly become one of the top setup men with the Twins in 2015 as a result.
Tonkin is a late bloomer who came on strong in the minors the past three seasons with outstanding strikeout rates and a mid-90s fastball. He began last season in Double-A, but aced his second trip to the level and then also posted a strong strikeout rate while showing good control at Triple-A. After he was called up in September he struck out 10 batters in 11.1 innings and did not give up an earned run until his ninth and final appearance with the Twins. Despite his fastball velocity (94.4 mph), Tonkin's age (24) could limit his upside, and he did give up five unearned runs with the Twins last year. Still, he could win a high-leverage role in Minnesota's bullpen with a strong spring.

On roster fringe
PNew York Yankees
May 14, 2024
Tonkin retained his place in the Yankees' bullpen when Nick Burdi was activated from the injured list Friday, as Ron Marinaccio was optioned instead, reports Gary Phillips of the New York Daily News.
Analysis
Tonkin joined the Yankees as a waiver claim in late April and seemed to be the likely odd man out with the bullpen gaining back a reliever, but he's apparently showed enough to stick around with five scoreless appearances. New York could also soon get back Tommy Kahnle from a shoulder injury, at which point Tonkin will likely again be in danger of losing his roster spot.
