Michael Harris II's outstanding rookie season in 2022 was followed by a stall in his development in 2023 that saw his power production plateau. A grade II hamstring injury limited him to 110 games in 2024, which also marked the beginning of the plate discipline problems that continue to keep him from reaching his considerable potential. The good news is that his underlying Statcast numbers have remained strong throughout his four seasons. He’s been focused on improving his plate discipline this spring, which could finally raise his productivity to a level more in line with his talent.

Michael Harris II's Decline Since Rookie Year

Stalled Development Limits Power/Speed Ceiling
Harris was promoted to the Major League club in 2022 at the age of 21, having played just 43 games at the Double-A level. Despite his excellent rookie season, the lack of experience has caused some growing pains in his development. Over the past two seasons his OPS has steadily declined, as poor swing decisions and plate discipline have led to his walk rate collapsing and poor quality of contact.
Harris II swings at far too many pitches outside the hitting zone. In 2025 he had the worst chase rate of all qualified batters. Surprisingly, he is able to make contact with a high percentage of those pitches but that contact is often of poor quality resulting in a high groundball rate. Nearly half of all the balls he puts in play are on the ground. Chasing all those pitches out of the zone has also caused his walk rate to completely crater. He started off in 2022 with a poor 4.8% rate, and finished last season at just 2.5%. The poor swing decisions are limiting his ability to get to his power stroke and keeping him off the bases, which limits his stolen base potential.
Steady Statcast Numbers and Underlying Strengths

Consistent Power Potential
There is a silver lining to what seems like a lot of doom and gloom. Despite all of Harris II’s plate discipline issues his Strikeout rate has stabilized at around 20%. More importantly, his underlying Statcast power metrics have remained quite steady over all four years of his MLB career thus far.
Consistency in those power metrics opens the door for Harris to be a more productive power hitter if he can improve the quality of his contact and hit more balls in the air to his pull side. His bat speed has been in the 82nd percentile or better among qualified hitters over the past three seasons. The 20 or so HR he’s hit each year can be considered his floor production at this point. If he makes the necessary plate discipline and swing decision improvements, he is capable of reaching 25 HR. Add in his 28.5 MPH Sprint Speed and there is no reason he can’t be a 25 HR/25 SB player if he can get back up to the .339 OBP he posted in his rookie season.
Spring Training Focus on Plate Discipline

Improvement Signals Bounceback
Harris II’s bounceback actually began after the All-Star break last year. During the second half of the season he had a .299/.315/.530 mark with 33 R, 42 RBI, 14 HR, and 8 SB. That was good for a .845 OPS, his highest mark since 2022. This spring he’s been focusing on his plate discipline, looking to lower his Chase Rate and raise up his Walk Rate. In 35 PA through March 19, Harris II has lowered his Chase Rate to 29.1% while drawing four walks for a rate of 11.4%.
While Spring Training stats aren’t predictive of in-season performance and we’re dealing with a very small sample size, they should put you on notice for the possibility of a bounceback 2026 season. Harris II’s ADP of ~98 puts him just inside the Top-25 OF. He’s a virtual lock for a 20/20 season if he remains healthy, but even incremental improvements could unlock 25/25 and perhaps more. He’s a solid mid-tier OF either way.
