The Cleveland Guardians are expected to promote catcher Bo Naylor to the majors ahead of Saturday's contest against the Arizona Diamondbacks, according to Jesús Cano of That news surfaces just a few hours after the Guardians designated veteran backstop Mike Zunino for assignment. 

Naylor, 23, has appeared in six big-league games over the last two seasons. He's authored a fantastic season in Triple-A so far this year, hitting .253/.393/.498 with 13 home runs and nearly as many walks as strikeouts. Naylor is, of course, the younger brother of Guardians slugger Josh. 

It's worth noting that the lefty-swinging Naylor has been particularly effective against righties this season. He's hit .271/.398/.510 against them, as opposed to .203/.370/.453 versus lefties. Naylor's average exit velocity is also much better against righties: 92.3 mph, contrasting his 87.1 mph mark versus lefties.

Zunino, 32, joined the Guardians over the offseason on a one-year deal worth $6 million. In 42 games, he batted .177/.271/.306 (63 OPS+) with three home runs and 11 runs batted in. Zunino, who has often struggled with strikeouts throughout his big-league career, fanned in 43.6% of his plate appearances. He's posted a 54 OPS+ over the last two years after an impressive 2021 campaign that saw him make his first (and so far only) All-Star Game.

In addition to Naylor, the Guardians have two other players on their roster who have caught games this season: Cam Gallagher and David Fry, who has appeared in 11 games a backstop. 

The Guardians entered Friday with a 32-36 record on the season, putting them in second place in the AL Central. They trailed the Minnesota Twins by 2 ½ games.
