Tyler Mattison: Everything you need to know

The Tigers re-signed Mattison to a minor-league contract Dec. 18 that includes an invitation to spring training, Evan Petzold of the Detroit Free Press reports. Mattison was non-tendered by the Tigers last month, but he's now back in the organization and will be in big-league camp this spring. The righty reliever boasts a 32.8 percent strikeout rate in the minors but has been held back by a bloated 13.4 percent walk rate.

Mattison was non-tendered by the Tigers on Friday. Mattison was designated for assignment Tuesday after being selected by the Tigers in the Rule 5 Draft last year. He'll now be a free agent after reaching Triple-A Toledo in 2025.

The Tigers designated Mattison for assignment Tuesday, Cody Stavenhagen of The Athletic reports. Mattison was added to the 40-man roster last November, but he finds himself on the other side of Rule 5 cutdown day this time around. The right-hander has yet to make his major-league debut. He pitched mostly between Double-A and Triple-A this past season after recovering from right UCL reconstruction surgery.
