Guardians designate Zunino, promote catching prospect Naylor.
The Cleveland Guardians are set to promote catcher Bo Naylor to the majors after designating veteran backstop Mike Zunino for assignment. Naylor, who is the younger brother of Guardians slugger Josh, has had a fantastic season in Triple-A so far this year. Zunino, who joined the Guardians over the offseason on a one-year deal worth $6 million, batted .177/.271/.306 in 42 games. The Guardians have two other players on their roster who have caught games this season: Cam Gallagher and David Fry.
