The Kansas City Royals designated a pair of major league players for assignment Wednesday to help make room for four new players on the 40-man roster.

The Royals added left-handed pitcher Foster Griffin, right-handed pitcher Carlos Hernandez, shortstop Jeison Guzman and outfielder Nick Heath to the 40-man roster ahead of Wednesday’s reserve list deadline.

To make room, the Royals designated outfielder Jorge Bonifacio and catcher Nick Dini for assignment. Both players spent time with the major league team in 2019.

The Royals also designated right-handed pitchers Conner Greene and Arnaldo Hernandez for assignment.

Bonifacio played only five games for the Royals after returning from an 80-game suspension by Major League Baseball for the use of performance enhancing drugs. He hit .350 with three RBIs before being sent back to Triple-A Omaha on June 21 when Hunter Dozier was activated off the injured list. Bonifacio hit .247 with 21 home runs and 66 RBIs in 187 games in three seasons.

Dini hit .196 with two home runs and six RBIs in 20 games with the Royals in 2019.

Griffin, 24, a first-round selection in the 2014 draft, was named a postseason all-star in the Pacific Coast League in 2019, going 8-6 with a 5.23 ERA in 25 starts with Triple-A Omaha.

Guzman, 21, who was signed as a non-drafted free agent out of Santo Domingo, D.R., was named the 2019 Lexington Player of the Year, batting .253 (114-for-450) with 23 doubles, five triples, seven homers and 51 runs in 121 games. The left-handed hitter helped the Class A Legends win their second-straight South Atlantic League championship.

Heath, 25, a 16th-round selection in 2016, led all minor league players with 60 stolen bases combined between Omaha and Double-A Northwest Arkansas. The left-handed hitter also tied for sixth in the Texas League with seven triples.

Carlos Hernandez, 22, originally signed as a non-drafted free agent out of San Felix, Venezuela, finished this season with Lexington, going 3-3 with a 3.50 ERA in seven starts after stints with rookie league teams in Burlington and Surprise earlier in the year.
