Royals demote Kelvin Herrera to Triple-A

3 Comments

Kelvin Herrera was one of the best relievers in baseball last season as a 22-year-old rookie, throwing 84 innings with a 2.35 ERA and 77/21 K/BB ratio while leading MLB with an average fastball velocity of 98.5 miles per hour.

He’s struggled this season, mostly due to serving up eight homers in 20 innings, but with a 4.87 ERA and 24/8 K/BB ratio he’s hardly fallen apart completely. But that didn’t stop the Royals from demoting Herrera to Triple-A today.

Herrera had a 1.92 ERA in 220 innings as a minor leaguer and has a 3.04 ERA in 107 innings as a major leaguer, so while this strikes me as an overreaction based on a small sample size mostly I just feel sorry for Pacific Coast League hitters.
