In 2019, the Kansas City Royals had a terrible bullpen. Only Baltimore had a worse ERA from their bullpen. The good news is that a decent bullpen can be built through minor league development and free-agent pickups.
The Royals have some up and coming options in guys like Scott Barlow, Richard Lovelady, Josh Staumont, and Kyle Zimmer. We also have some minor league guys like Gabe Speier and Grant Gavin that should become reasonable bullpen arms.
The bad news is that we have been unable to develop or find much in free agency over the last couple of seasons.
