Royals Option Mitch Spence to Omaha – Notes

On Wednesday, the Kansas City Royals announced that they had optioned right-handed pitcher Mitch Spence to Triple-A Omaha to begin the season. This latest move now brings their Major League Spring Training roster to 49. 

Spence was acquired by the Royals from the Athletics this offseason in exchange for right-hander A.J. Causey. Spence was the top overall pick in the 2023 Rule 5 Draft, and he pitched two seasons with the Athletics before arriving in Kansas City. 

In 2024, the former Yankee pitching prospect was a hybrid arm for the Athletics, making 35 appearances (24 starts) and pitching 151.1 innings. In that sample, he posted a 4.58 ERA, a 1.38 WHIP, a 4.14 FIP, and 12.6% K-BB%.

He took a step back in his second year with the Athletics, pitching only 84.2 innings and making only eight starts (32 total appearances). In that more abbreviated campaign, Spence posted a 5.10 ERA, a 1.44 WHIP, a 5.06 FIP, and 10.7% K-BB%. His Statcast percentiles were also a bit mixed last year, as seen below via his TJ Stats Statcast summary.

The 27-year-old did a good job of generating whiffs, limiting walks, and generating chase and groundballs last year with Sacramento. However, he also gave up a lot of hard contact, and that hurt him in Sacramento’s hitter-friendly confines. He posted a 6.93 ERA at home compared to a 3.64 ERA on the road. Thus, the move to Kauffman Stadium should help Spence in 2026.

This spring was a rough one for Spence, albeit a limited sample. In three appearances (two starts) and 7.0 IP, he posted a 10.29 ERA, 1.71 WHIP, 7.53 FIP, and 3.0% K-BB%. Spence has been hurt by the long ball, as evidenced by his 28.6% HR/FB rate. However, his TJ Stuff+ metrics have been encouraging, as shown in his TJ Stats summary below.

Spence had a 106 overall TJ Stuff+ this spring with his cutter (108), slider (111), and curveball (101) all rating as above-average pitches. He generated a 31.6% chase rate, which was above average, but his zone rate and whiff rate were slightly below average, and his xwOBACON of .424 was well below average. Thus, it was more of a command issue for Spence in Cactus League play, and hopefully, he can work that out in Omaha.

With the Spence move, Bailey Falter, Alex Lange, Hector Neris, and Eli Morgan are the main relievers remaining in camp. They are battling for two spots in the Opening Day bullpen.

Lange and Falter are likely the favorites for those remaining spots, especially since they are out of Minor League options. Morgan has had a strong spring for the Royals, however. The former Cleveland reliever is posting a 1.17 ERA, 1.17 WHIP, 1.80 FIP, and 18.8% K-BB%. He has also shown solid Statcast percentiles this spring in his Cactus League sample. 

Morgan does have a Minor League option remaining, but if he doesn’t make the Major League squad out of Spring Training, he could opt to find a spot in the bullpen on another MLB team. Thus, it will be interesting to see what the Royals will do with Morgan, especially in the wake of the Spence move and Opening Day only nine days away.
