The Royals have added another arm to their spring bullpen puzzle, signing former Cardinals reliever Seth Maness to a minor-league deal, according to the St. Louis Post-Dispatch.
Maness, 28, posted a 3.19 career ERA in 244 appearances across four seasons in St. Louis, including a 3.41 ERA in 29 games last season. But in baseball circles, he is perhaps best known for undergoing an experimental procedure on his elbow after damaging his ulnar collateral ligament last summer — an injury that usually requires Tommy John surgery.
Maness underwent the new surgery lasts Aug. 18, according to the Post-Dispatch.
