Brentz (elbow) signed a two-year deal with the Royals on Thursday.
Brentz underwent Tommy John surgery in the middle of July, so he's likely to miss the entire 2023 season. Prior to going down with the arm issue in 2022, he made only a few appearances with the Royals and allowed 14 earned runs across 5.1 innings with nine strikeouts and 10 walks.
