A’s Trade Mitch Spence To Royals

The Athletics have traded right-hander Mitch Spence to the Royals in exchange for minor league righty AJ Causey, per announcements from both clubs. Spence was designated for assignment by the A’s earlier this week. Kansas City placed righty Alec Marsh on the 60-day IL to open a roster spot for Spence.

The 27-year-old Spence didn’t have to wait long to find a new home after getting DFAed on Tuesday. He’ll head to Kansas City as a depth option behind a fairly set rotation. Marsh had labrum surgery in November and is set to miss the 2026 season. His placement on the 60-day was a formality.

The Athletics added Spence as a Rule 5 pick from the Yankees ahead of the 2024 season. He emerged as a mainstay in the rotation that year, piling up 151 1/3 innings across 35 appearances (24 starts). Spence posted an ERA in the mid-4.00s with subpar strikeout numbers. He did well to limit walks and got ground balls at an above-average clip.

The offseason additions of Jeffrey Springs and Luis Severino squeezed Spence out of the rotation. He made 32 appearances with the club, mostly out of the bullpen. Spence briefly returned to the rotation in June. His performance as a starter (5.05 ERA, 11 home runs allowed) led to a demotion to the minors. Spence returned to the A’s in September. He was hammered for nine earned runs in 10 innings to close the season.

Spence will be built up as a starter with Kansas City, but the club likes that he has experience in both roles, notes Anne Rogers of MLB.com. The Royals currently have Bailey Falter penciled into the swingman role.

Kansas City took Causey in the fifth round of the 2024 draft out of Tennessee. The 23-year-old right-hander began his pro career at High-A this past season. After 40 1/3 innings of a 1.56 ERA with Quad City, he made the jump to Double-A. Causey maintained a sub-2.00 ERA in 21 games with Northwest Arkansas. He compiled a 1.72 ERA with more than a strikeout per inning in 48 appearances across the two levels. Scouting grades laud Causey’s slider and changeup. His sidearm delivery helps his 90 mph fastball play up.
