The Royals released Duffey on Tuesday, Robert Murray of FanSided.com reports.

EDGE Analysis

The right-hander has been at Triple-A Omaha since being designated for assignment in late May, and he's now been released. Duffey allowed five runs with a 10:8 K:BB over nine innings with the Royals and pitched to a 2.35 ERA, 1.16 WHIP and 34:11 K:BB in 23 outings for Omaha.

The Royals outrighted Duffey to Triple-A Omaha on Wednesday.

EDGE Analysis

Duffey is no longer on the Royals' 40-man roster but appears set to remain in the organization. The veteran right-hander has collected a 5.00 ERA, 1.67 WHIP and 10:8 K:BB over nine innings at the big-league level this season.

The Royals designated Duffey for assignment Friday.

EDGE Analysis

The right-hander was added to the Royals' roster in late April and posted a 5.00 ERA, 1.67 WHIP and 10:8 K:BB over nine innings during his month in the majors. Duffey was removed from the 26-man and 40-man rosters to clear a spot for the return of Carlos Hernandez (shoulder).

Duffey (1-0) pitched a perfect inning and earned the win over the Angels on Friday.

EDGE Analysis

The Royals saved their offense for late, and Duffey ended up benefiting from it after keeping the deficit to one run in the eighth inning. He's kept runs off the board in four of his six major-league appearances this season. The right-hander has a 4.05 ERA, 1.50 WHIP and 8:5 K:BB over 6.2 innings while adding one hold, though he's primarily served as a low-leverage option.

The Royals selected Duffey's contract from Triple-A Omaha on Monday.

EDGE Analysis

Kansas City had a spot on its 40-man roster open for Duffey after Jordan Lyles (personal) was placed on the inactive list over the weekend. Duffey, who made just one appearance at the big-league level in 2023 as a member of the Cubs, posted a 3.24 ERA and 1.36 WHIP over 8.1 innings across six relief appearances for Omaha this season.

The Royals are expected to call up Duffey from Triple-A Omaha on Monday, Jon Heyman of the New York Post reports.

EDGE Analysis

Duffey will move up to the majors after compiling a 3.24 ERA and 10:5 K:BB over 8.1 innings with Omaha this season. The 33-year-old made just one appearance in the majors in 2023 and wasn't great with the Twins in 2022, but Duffey holds a career 3.99 ERA and 301:85 K:BB across 284 innings as a reliever at the big-league level.

Duffey (back) has made two appearances out of Triple-A Omaha's bullpen so far this season, striking out four batters over three innings while allowing one earned run on one hit and two walks.

EDGE Analysis

Duffey didn't pitch at all for the Royals during the Cactus League after Feb. 26 upon requiring surgery to remove a cancerous mole from his back. The medical issue derailed any hopes Duffey had of making the Royals' Opening Day bullpen, but fortunately, the 33-year-old has been able to resume his playing career in the minors after a relatively brief delay. He'll look to stack together more quality relief appearances at Triple-A with the hope of eventually receiving a call-up to Kansas City.

Duffey has been sidelined since Feb. 26 after having surgery to remove a cancerous mole from his back, MLB.com reports. He started light baseball activity Wednesday.

EDGE Analysis

A suspicious mole on Duffey's back was diagnosed as melanoma during an exam early in spring training. Duffey hopes to pitch in games by the end of spring training, but it appears likely he'll begin the season on the injured list. He signed a minor league deal with the Royals and is attempting to win a spot in the major league bullpen this spring.

Duffey signed a minor-league contract Thursday with the Royals.

EDGE Analysis

Duffey made only one MLB appearance with the Cubs in 2023 and held a 3.77 ERA and 53:23 K:BB in 45.1 innings with their Triple-A affiliate in Iowa. The 32-year-old right-hander owns a career 4.57 ERA in the big leagues.

The Cubs selected Duffey's contract from Triple-A Iowa on Sunday, Meghan Montemurro of the Chicago Tribune reports.

EDGE Analysis

The right-hander was cut loose by the Cubs in early June but resigned on a minor-league deal a couple weeks later. Duffey posted a 4.91 ERA in 40 outings with Minnesota last year and had a 3.77 ERA over 45.1 innings at Triple-A this season.
