Royals Sign Michael Fulmer To Minor League Deal

The Royals announced Thursday that they’ve signed righty Michael Fulmer to a minor league contract. He’s been assigned to Triple-A Omaha. Fulmer, a client of BBI Sports Group, recently passed through waivers and elected free agency after being designated for assignment by the Cubs.

Fulmer, 32, is a former American League Rookie of the Year whose career has been slowed by injuries. He was an integral part of the Tigers’ rotation for three years before elbow and knee surgeries pushed him to the bullpen. He found second life as a reliever with the Tigers, Twins and Cubs from 2021-23 before a torn UCL required Tommy John surgery and wiped out his entire 2024 campaign. He spent all of last year and the beginning of the current season in the Red Sox organization after inking a two-year minor league contract, but the Royals are now his third organization before the All-Star break.

Fulmer started 75 games with the Tigers from 2016-18 and posted a combined 3.81 ERA. His 2021-23 work as a closer and setup man resulted in another 190 1/3 innings of 3.55 ERA ball. He fanned 24.6% of his opponents in that time against a 9.4% walk rate, and Fulmer added in 19 saves and 45 holds along the way.

Though his return from Tommy John surgery hasn’t yet netted him a lengthy look in the majors, he did get into three games between Boston and Chicago this season. In that time, he pitched a combined 5 2/3 innings and allowed three runs on six hits and a pair of walks with three strikeouts.

The bulk of Fulmer’s 2025 season, however, has been spent in Triple-A. He’s tossed 36 innings between the top affiliates for the Red Sox and Cubs, recording a sharp 3.00 ERA with a huge 33.8% strikeout rate against a shaky 11.5% walk rate. He’s sitting 92.7 mph with his four-seamer in Triple-A, which is down about 1.5 mph from his pre-surgery form.

Kansas City has had a quality bullpen in 2025, ranking sixth in the majors with a collective 3.55 ERA. They’ve been more of a middle-of-the-pack group over the past month, however, pitching to a 16th-ranked 3.94 ERA in that time. They’ve still gotten mostly solid work from their top relievers, but they’ve cycled through several names in the final couple bullpen spots and received poor performance over the past month. Trevor Richards, Sam Long and Taylor Clarke all have ERAs north of 6.50 in that span (albeit in a total of just 19 innings between the three of them). Fulmer will add a veteran arm to the depth chart in Omaha and could get a look as the summer wears on.
