Keller has spent the 2025 season with the Chicago Cubs after making the team as a non-roster invitee in the spring. The Cubs took a 1-game-to-none lead in the best-of-three NL Wild Card series. Interestingly enough, while one former Royals friend was closing things out, it was a familiar foe who kicked things off. There is, in fact, no team Boyd has faced more over the course of his career than the 30 games pitched against the Royals. While Boyd has spent most of his career as a foe to the Kansas City Royals, he was never particularly effective, posting a 9-11 record and a 4.98 ERA.
