The Guardians will promote slugging prospect Kyle Manzardo prior to tomorrow’s game with the Tigers, according to The Athletic’s Zack Meisel (X link).  Cleveland has an open space on its 40-man roster to add Manzardo, and the 26-man space will be created when outfielder Steven Kwan is placed on the 10-day injured list.

Kwan left Saturday’s game due to hamstring tightness and was set to undergo an MRI today.  The results of the tests aren’t yet known, but even if the MRI is clean, the Guards might’ve felt it necessary to sideline Kwan anyway given his long history of hamstring problems.  As Kwan explained to reporters (including Paul Hoynes of the Cleveland Plain Dealer) yesterday, he has battled hamstring issues both in the minors and during his college days.

Losing Kwan for any amount of time is a blow to the Guardians, as his huge early-season performance has fueled Cleveland’s rise to first place in the AL Central.  Kwan is hitting .353/.407/.496 over 145 plate appearances, leading the American League in both batting average and hits (47).  Some regression is inevitable since Kwan has a .370 BABIP and has continued to make some of the weakest contact of any hitter in baseball, but the Guards were happy to ride that offensive wave for as long as possible.  In addition to this surge at the plate, Kwan has also been delivering his customary superb left field defense, and looks like a favorite to win his third straight Gold Glove.

Will Brennan got the start in left field today, but the Guardians will probably keep the Brennan/Ramon Laureano platoon going in right field and address Kwan’s absence by using Estevan Florial a bit more regularly in left.  Florial has gotten the bulk of DH at-bats for Cleveland this season, yet the team will now need the designated hitter spot as a way to get Manzardo (who only plays first base) and Josh Naylor in the lineup at the same time.  Gabriel Arias and David Fry also figure to get some playing time in the corner outfield in certain situations.

A second-round pick for the Rays in the 2021 draft, Manzardo came to Cleveland at last year’s trade deadline in the one-for-one swap that sent Aaron Civale to Tampa Bay.  Manzardo’s minor league numbers had already drawn him top-100 prospect attention prior to the trade, and he has only gotten better since joining the Guardians organization.  Manzardo is hitting .303/.375/.642 with nine home runs over 128 PA with Triple-A Columbus this season, and while the Guards chose to start him at Triple-A rather than add him to their Opening Day roster, it only seemed like a matter of time before Manzardo made his MLB debut.

MLB Pipeline ranked Manzardo 52nd on its list of the sport’s top 100 prospects, and Baseball America has him 87th.  (For lists released prior to the season, The Athletic’s Keith Law ranked Manzardo 66th and ESPN’s Kiley McDaniel had him 83rd.)  The consensus is clear — Manzardo’s bat is definitely ready for the big leagues, though the 23-year-old might already be ticketed for a DH-only future even in a world where Cleveland didn’t have Naylor locking down first base.  Manzardo is viewed as a decent first baseman at best, and his lack of speed makes him an implausible choice to play outfield.

At the plate, however, Manzardo is a threat.  He both makes a lot of hard contact and a lot of contact in general, befitting the Guardians’ preference for hitters who rarely strike out.  Manzardo has 50 home runs over his 990 PA in the minors, and there is some sense that he might be able to unlock more power given how well-developed his approach is in the batter’s box.

This is music to the ears of a Guardians team that has long been lacking in power, though Cleveland’s offense has been greatly improved in the early going this season.  Naylor has been a big contributor to that more dangerous lineup, but since Naylor is a free agent after the 2025 season, there has been a sense that Manzardo might well be the heir apparent at first base.  Cleveland’s history of trading pricier players prior to free agency could make Naylor a big trade chip this coming offseason, so while a nice showing from Manzardo in his rookie season would certainly help the Guardians’ chances in 2024, it might have the Catch-22 of also hastening Naylor’s eventual departure.

Even if he stays on the Guards’ roster for the rest of the season, Manzardo won’t earn quite enough service time for a full season of MLB service.  As a result, he wouldn’t garner the Guardians an extra draft pick under the Prospect Promotion Incentive even if he had a top-two finish in Rookie Of The Year voting.  It is possible Manzardo might earn Super Two status and an extra year of arbitration eligibility if he garners enough service time over his first three seasons, though we won’t know that answer until the 2026 season is complete.
