Jackson Holliday’s 2026 season has shown clear progress, but it is better described as an encouraging step toward becoming a quality everyday player than a full superstar breakout.

Through 60 games and 194 plate appearances, the 22-year-old is hitting:

AVG OBP SLG OPS ISO BB% K% wRC+ WAR

.252 .356 .387 .742 .135 14.4% 25.3% 113 0.9

The 113 wRC+ means Holliday has been approximately 13% better than the league-average hitter after adjusting for league and park. That is valuable production from a 22-year-old middle infielder, particularly after he struggled badly during his initial MLB exposure.

His improvement is being driven by walks, better batted-ball distribution and more consistent competitive plate appearances. It is not being driven by elite bat speed, exceptional contact ability or a major power breakout. At this point, Holliday profiles as an above-average offensive second baseman with the potential to become more, but there are still meaningful weaknesses underneath the surface statistics.

Development from 2024 to 2026

In 2024, he hit only .189/.255/.311 with a 33.2% strikeout rate and 62 wRC+. He was clearly overmatched, particularly against breaking pitches.

He improved considerably in 2025, finishing at .242/.314/.375 with a 96 wRC+. Most importantly, his strikeout rate fell from 33.2% to 21.6%. He still was not producing much power or reaching base at a high level, but he looked much more like a viable MLB hitter.

His 2026 improvement has come in a different form. His strikeout rate has increased to 25.3%, but his walk rate has jumped from 8.6% to 14.4%. That increase has allowed him to produce a .356 OBP despite only hitting .252.

The overall progression is therefore:

• 2024: Overmatched and striking out excessively.
• 2025: Much better contact rate, but only slightly below-average overall production.
• 2026: More selective and reaching base frequently, though some swing-and-miss has returned.

How sustainable is the 2026 production?

There is not a massive difference. Holliday has received somewhat better results than his contact quality would normally produce, but he is not surviving on an extreme amount of luck.

His .321 BABIP is above his career .291 mark and has helped his batting average. The expected statistics suggest that his underlying offensive performance has probably been closer to a 105–110 wRC+ level than a his current 113-plus level.

That interpretation also matches the projection systems. The remaining projections generally place him between 102 and 112 wRC+, with most expecting an average in the .240s, an OBP around .330 and a slugging percentage close to .390–.410.

Plate discipline and approach

The walk rate is his biggest improvement

Holliday’s 14.4% walk rate is the strongest element of his 2026 profile. He is no longer dependent on batting average to reach base and is forcing pitchers to throw him strikes.

He is swinging less frequently overall, which is helping him work deeper counts and draw walks. He only swings at 24.1% of chase-zone pitches and almost never offers at complete waste pitches.

However, the underlying picture is not entirely positive. His chase rate is actually slightly higher than it was in 2025, while his contact rate has dropped by more than five percentage points. His zone-contact rate has also fallen.

That means the increased walk total is not simply the result of flawless swing decisions. Holliday is receiving fewer pitches in the strike zone—47.4% compared with 53.8% in 2025—and is taking more pitches overall. Pitchers are being more careful with him, and he has taken advantage of that caution.

Contact ability

A 72.8% overall contact rate, 81.8% zone-contact rate and 11.7% swinging-strike rate describe a hitter with noticeable swing-and-miss. His 25.3% strikeout rate is manageable, especially alongside a 14.4% walk rate, but it remains higher than ideal for a hitter who does not possess elite power.

The most encouraging point is that Holliday has already demonstrated that he can make more contact. His strikeout rate was 21.6% in 2025, and his zone-contact rate was nearly three percentage points higher. There is therefore a reasonable path toward combining his 2026 patience with something closer to his 2025 contact rate.

That combination would significantly raise his offensive ceiling. A 12–14% walk rate paired with a strikeout rate around 21–23% would make him a far more complete hitter.

Bat speed and swing characteristics

His 70.6 mph average bat speed and 6.8% fast-swing rate are modest. He is not consistently creating the type of explosive swings associated with elite raw power.

The attack-angle numbers are generally functional. His 10-degree attack angle matches reasonably well with his 11.9-degree average launch angle. He is capable of getting the ball into the air without using an extreme uppercut.

The concern is that his blast rate per swing is only 8.9%. He does not combine optimal contact, bat speed and launch angle frequently enough to project as an impact power hitter right now.

Exit velocity and power

Current contact quality

The 7.7% barrel rate is adequate, but the rest of the contact-quality profile is underwhelming. His average exit velocity and hard-hit rate have declined in each of his three MLB seasons.

His maximum exit velocity has also fallen from 109.6 mph in 2025 to 105.8 mph in 2026. Because the 2026 sample is only 117 tracked batted-ball events, that does not necessarily mean he has lost strength. It does mean that he has not yet displayed his best raw power this season.

Holliday’s .135 ISO matches the underlying data. He currently has moderate game power, not impact power. Over a full season, this profile is more consistent with approximately 14–18 home runs than 25 or more.

His power is being created more through launch angle and occasional barrels than overwhelming exit velocity. He can punish mistakes, but he is not regularly driving well-located pitches with elite force.

Batted-ball profile

His groundball rate has declined by more than 11 percentage points since 2024, while his line-drive rate has more than doubled.

The 2026 version of Holliday is producing a much healthier mix of line drives, fly balls and groundballs. That helps explain why his BABIP has risen and why his expected slugging percentage is better than it was during his rookie season.

One concern is his 9.8% infield-fly rate, which has risen from 2.3% in 2024 and 5.3% in 2025.

Directional contact and pull-side power

• Pull: 40.2%
• Center: 34.2%
• Opposite field: 25.6%

When Holliday pulls the ball, 63.8% of those batted balls are groundballs, while only 21.3% are fly balls and 14.9% are line drives. By comparison, his center-field and opposite-field contact is much more likely to be elevated.

That is currently limiting his power. Holliday pulls the ball frequently enough, but much of that pull-side contact is rolled over on the ground. His airborne contact is more commonly directed toward center or the opposite field, where more exit velocity is required to produce home runs.

He should not simply attempt to pull every pitch. His opposite-field ability is useful. He needs to better distinguish between pitches he should drive to right field and pitches he should allow to travel toward center or left.

Performance by pitch type

Four-seam fastballs are his clearest strength

He has produced a 155 wRC+ against four-seam fastballs, with strong on-base ability and his best reliable power production. His improvement against velocity is significant because four-seam fastballs were not a major strength during his first two seasons.

His results against sinkers are more complicated. He has a strong .382 OBP, largely because of a 20.6% walk rate, but only a .259 SLG and .037 ISO. He recognizes sinkers well enough to avoid chasing them, but he is not consistently driving them.

Offspeed pitches remain the main weakness

Changeups have been his worst pitch type by a wide margin. He is hitting only .105/.150/.105 against them, with no extra-base damage.

Sliders have also given him problems. His .172/.297/.276 line and 79 wRC+ show that he is not consistently squaring them, although his 16.2% walk rate demonstrates that he can still avoid some of the worst pitches.

He has struck out in 50% of plate appearances ending on curveballs. That sample is small, but it supports the broader concern that quality spin and speed separation can disrupt him.

His enormous results against cutters and splitters should be treated cautiously because he has seen only 43 cutters and 35 splitters. The production is encouraging, but those samples are too small to establish true skill.

Improvement against changeups and sliders is probably the single most important offensive development remaining.

Platoon splits

His similar on-base percentages are encouraging. Even against left-handed pitchers, Holliday has drawn enough walks to remain productive.

There is still a notable quality difference. His strikeout rate rises to 31.0% against lefties, while his ISO falls to .114. He survives those matchups through walks and a high BABIP rather than consistently authoritative contact.

He should remain in the lineup against left-handed pitching. Nothing here suggests that he needs to be platooned. However, he is currently more likely to reach base than produce extra-base damage against same-handed pitchers.

Recent performance and the July surge

July was extremely encouraging because Holliday simultaneously raised his walk rate and cut his strikeout rate. That is exactly the type of improvement needed for him to become a better all-around hitter.

However, the results were also supported by a .447 BABIP, while his July ISO was only .053. He did not suddenly unlock major power. He generated excellent results by putting the ball in play, controlling the strike zone and having a large percentage of those balls fall safely.

The second-half line of .364/.442/.409 and 145 wRC+ is encouraging, but it covers a limited number of plate appearances. It should be viewed as evidence of progress rather than proof that he is now a 140-plus wRC+ hitter.

Baserunning and situational value

His 5.2 speed score, +0.2 XBR and +0.3 wSB suggest average speed and generally sound decisions. He is not a major stolen-base threat, but he is not hurting the team through poor baserunning.

His situational performance has also been mildly positive:

• WPA: +0.69
• RE24: +5.10
• WPA/LI: +0.57
• Clutch: +0.05

The clutch rating is essentially neutral. Holliday has contributed positively in important situations, but there is no strong evidence that he has performed differently in pressure situations than in ordinary plate appearances.

Defensive evaluation

Defense remains an important limitation.

In 430.2 innings at second base during 2026, Holliday has recorded:

• -2 Defensive Runs Saved
• -1 Outs Above Average
• -2 Fielding Run Value
• Neutral throwing value
• Slightly negative range value

The 2026 numbers are only mildly below average, but his larger career sample is more concerning. Across 2,093 innings at second base, he has accumulated approximately:

• -14 DRS
• -8 OAA
• -7 FRV

Range appears to be the primary issue. His throwing has generally been neutral, but he has not consistently reached enough balls to provide average overall value at the position.

He has played a few innings at shortstop and third base, but the samples are too small to draw meaningful conclusions. Nothing in the supplied data suggests that either position is currently a superior defensive home.

Second base remains his best position, but his defense places additional pressure on the bat. A 105–110 wRC+ hitter with below-average defense can still be a regular, but that combination is more likely to produce two to three WAR than star-level value.

For Holliday to become a four- or five-WAR player, he will probably need one of two developments:

1. Improve his second-base range enough to approach average defense.
2. Develop into a consistent 120–130 wRC+ hitter.

Projection

Holliday’s current true-talent offensive level likely falls around:

• .240–.260 AVG
• .330–.355 OBP
• .390–.420 SLG
• 105–115 wRC+
• 15–20 home runs over a full season
• Approximately 2.5–3.5 WAR with regular playing time

That would make him a solid everyday second baseman, though not yet one of the top players at the position.

Ceiling outcome

Holliday can move toward a 120–130 wRC+ level if he:

• Maintains a walk rate above 11–12%.
• Reduces his strikeout rate closer to 21–22%.
• Produces more pull-side line drives and fly balls.
• Improves against changeups and sliders.
• Recovers some of his previous maximum exit velocity.
• Becomes closer to average defensively.

That version could hit 20–25 home runs, post strong on-base percentages and produce four or more WAR in his better seasons.

Lower-end outcome

The lower-end outcome emerges if his 2026 walk rate regresses while the strikeout rate remains around 25%. Without stronger contact quality, he could settle closer to a 95–105 wRC+ hitter.

Combined with below-average second-base defense, that would make him more of an ordinary regular than a foundational player.

Final verdict

Jackson Holliday is moving in the right direction. He has progressed from being badly overmatched in 2024 to becoming a productive MLB hitter in 2026. His ability to draw walks and handle four-seam fastballs gives him a legitimate offensive foundation.

At present, Holliday looks like a solid everyday second baseman with above-average on-base ability and moderate power. His path toward becoming an impact player depends on turning more of his pull-side contact into damage, improving against offspeed pitches and preventing his defensive limitations from reducing too much of his offensive value.
