Pitcher List’s Week 18 “Patience or Panic” entry puts Kyle Stowers in the headline, but the body turns quickly to Kyle Manzardo and a far starker question: what happened to a hitter who looked like a breakthrough last year and now looks like a problem. Manzardo, 24 during his 2025 season, has gone from a regular MLB role and 27 home runs to a.209/.298/.358 line through 95 games in 2026.
That is the part that makes the search feel urgent today. His July OPS has fallen to.429, second-worst in MLB behind Colt Emerson’s.373 mark, and over his last 22 games he is hitting.134/.205/.254. For a player once treated as a power source, the drop is not just in average. It is in the shape of his production.
Manzardo’s 2025 season gave the Cleveland Guardians a reason to believe the bat had arrived. He hit.234/.313/.455 with 19 doubles, 70 RBIs, a.768 OPS and a 113 wRC+, numbers that looked far better than the Triple-A line that preceded them, when he posted a.945 OPS with 20 home runs in 2024. The Guardians had acquired him from the Tampa Bay Rays in 2023 for Aaron Civale, and the move had already lived through enough roster churn to make any breakout feel important.
This is why the decline lands so hard. Manzardo is a power-first hitter, and the power has backed up. His home run rate has dropped from 5.1% in 2025 to 3.3% in 2026, his barrel rate has fallen, and his slugging percentage is now 125th out of 147 qualified hitters. He ranks 97th in ISO, which is not where a left-handed slugger wants to live when the job is to punish mistakes rather than merely put the ball in play.
The split data is even less forgiving. Manzardo has struck out 52 times on fastballs, 37 times on breaking balls and 16 times on offspeed pitches. He is hitting.261 against fastballs, but.159 against breaking pitches and.132 against offspeed pitches. Against sliders, one of the pitches that has bothered him most, he is at.122 with a 48.8 Whiff% and a 41.7 K%.
That is the friction inside the profile: the swing that once translated into damage now gets beat by almost everything it sees. His strikeout rate has climbed from 25.4% to 31.7%, a number that sits in the seventh percentile of all players, while his results against changeups are barely better at.135 with a.135 slugging percentage. Even in a season measured over a long enough sample, the trend line is moving the wrong way fast.
Manzardo still has age on his side, and his 2025 production was good enough to make this 2026 slide feel like a warning rather than a verdict. But with his July OPS at.429 and the contact quality down across the board, the question is no longer whether he broke out. It is whether the league has already found the way to take that breakout apart.
