What is Royce Lewis ’ role on the Minnesota Twins this year? It’s a valid question, and conversations about whether he’ll live up to his full potential are just as valid. The thing with Lewis is, he’s showing flashes of greatness this year, and what he's accomplished in the last couple of weeks is a perfect example of that. Let’s dive into Lewis’ background, his advanced analytics, and most importantly, what his true ceiling is. 

A 1st Overall Pick

Lewis was the first overall pick in the 2017 MLB Draft. The Twins selected him right out of high school, aiming to land a well-rounded prep product who could blossom into being the cornerstone of their organization. While that title has gravitated more towards Byron Buxton in past years, Lewis’ journey to the present day has been an intriguing one. 

He immediately showed an ability to harness a power-speed combo, stealing as many as 28 bases in 2018 (across Low-A Cedar Rapids and High-A Fort Myers) and having an OPS that peaked above .800 on multiple occasions. 

Injuries Galore

The unfortunate headline for Lewis’ major league career, so far, has been his lack of availability. Injuries have plagued the now 27-year-old since the moment he made his big league debut in 2022, where he appeared in 12 contests. From that point forward, Lewis appeared in 58 big-league games in 2023, 82 games in 2024, a career-best 106 contests in 2025, and now he’s on 82 games and counting for the 2026 campaign.

The former first overall pick has dealt with a pair of torn ACLs, hamstring strains, a strained oblique, and a variety of other knee issues along the way. Even with those issues, an 82-game sample size where Lewis slugged 16 home runs in 2024 shows he has potential to be a real game changer for Minnesota.

Underlying Metrics Show Promise

Even in 2026, after being sidelined for a variety of reasons, the corner infielder is on a heater. Lewis has reached base safely in 18 straight contests. During this on-base streak, he's slashing .308/.378/.554 for a .932 OPS. Lewis is also 11-for-24 in the month of August.

Much of this success starts with one of the most important attributes in hitting: bat speed. Lewis’ bat speed glides in at an average of 75.1 miles per hour, good enough to nestle him in the 85th percentile. Hard-hit metrics like exit velocity, hard-hit rate, slugging percentage and more all become more attainable with great bat speed. Just look at someone like Junior Caminero, who lives in the top one percent of hitters with bat speed and continues to slug homers at a remarkable rate. 

Another metric that can benefit from an above-average bat speed is barrel percentage, and Lewis is barreling up the baseball 12.8 percent of the time (84th percentile). 

The Twins infielder has also spiked his exit velocity to an above-average mark of 90.2 miles per hour (67th percentile) and also boasts an above-average hard-hit rate of 43.4 percent (63rd percentile). One of his greatest improvements this year has been the plate discipline, as the 27-year-old is drawing a free pass 9.3 percent of the time (a career-best). 

What’s There To Work On?

Lewis still has a lot of work to do, especially in the plate discipline department. His 24.3 percent strikeout rate is something I’m sure the Twins would love to cut down on, and if he can do so, his power numbers could rival that of Buxton. Lewis doesn’t have the bat speed quite up the alley of the aforementioned Caminero, but his analytics imply he could be a successful power hitter in this league if he stays on the field and learns to adjust to offspeed pitches, an offering he’s hitting just .111 against this year.

Overall, this 18-game stretch is one of the most promising mile-markers of Lewis' career. The former first overall pick hasn't had the start he's been looking for, but with a better track record for health and improved plate discipline, the raw power metrics still support an argument that he can be a real difference-maker in this league.

Twins must keep both Royce Lewis & Austin Martin as America can not survive another Lewis & Martin breakup.

[Linus]

Hope he keeps it up. We need difference makers in the lineup. I know this isn’t new age but I think he should go with the outside pitch more. Some doubles to right / center will get him some inside pitches which he really likes. 

[Bodie]

He needs some consistency. His highs are otherworldly, but rare.  His lows are bafflingly bad and all too common. 

I have some hope left that he can play at a star level, but six month hiatuses in any sort of productive play makes it hard.

[bean5302]

Lewis is still making adjustments, and the line drives are showing up, but his pop up rate is still too high. Still, he's hitting the ball extremely well over his past 20 games, and he was already hitting well the 20 games before that.

I'm not sure what his ceiling is anymore. Also not concerned with a 24% K rate. Median average for MLB qualified hitters is 21%.

[Craig Arko]

I suspect the lower half of his body is finally healthy, so he can drive the ball.

[HarmonK03]

He finally went back to what got him to the major leagues.  He has been going with the pitch more to RF, one example was the walkoff hit against KC and I think he will continue.

I really don't the Twins tinkering with him right now.  This front office has a history of trying to change the swings of our prospects going all the way back to Buxton and it has never worked out.  Martin, Lee and now Lewis have all mentioned this.  It is one thing to work and suggest tweaks within their normal framework but they have tried to completely overhaul swings and it's not working.

[nicksaviking]

I truly forget how great he was until September of 2024. It was legit MVP production for most of 2024. I’d been thinking it was the fantastic start in 2023 then the inconsistency. 
 

Last week I was on board with trading him in a package, now I’m thinking I want to see  if second half 2026 can be repeated or improved in 2027.

Maybe he’s just guy who plays well when there’s a winning atmosphere and falls asleep when it’s a losing atmosphere? That’s kind of damning, but I expect wining next year. 

[Fatbat]

Like Buxton, Lewis is going to age like a fine wine. Injuries just suck but when healthy, Lewis is a super star talent. At 27 yo, he should be signed to. 5-6yr deal in the $17.5M/yr range. Under $20M just because of his availability issues. Cheap Pohlads will never take the chance on him tho. 

[Richie the Rally Goat]

To the OP, it’s a silly nit-pick, but I’m going to do it anyways.

Barrels is a hard hit stat that is right in line with the rest of his hard hit stats. Calling that out separately while also lumping other hard hit stats loses some credibility to an otherwise very good article.

the comment about Lewis, like Buxton, aging like fine wine distilled the conversation extremely well.

Buxton’s excellent hitting on rate stats have been in place since his age 25 season, it wasn’t until his 30s that health allowed the counting stats to catch up.

Lewis has been far more inconsistent. I’m skeptical that Royce will age well. It’s great to see him on a heater, I look forward to him proving me wrong

[stringer bell]

IMHO Lewis had two consecutive seasons ruined by injuries and is wasn't the ACLs. The soft tissue injuries put Royce on the shelf and he came back twice when he wasn't ready and was a shadow of himself. The conclusion of 2025 wasn't great, but he was healthier and moving like a young man instead of Giancarlo Stanton. You'll note his sprint speed is up this year and he's 11-11 in stolen bases. 

The confidence is back and he's hitting very well. I still think there are a few too many moving parts in his hitting approach and that he'll have slumps, but this is a talented guy who has come to terms with what his body offers and he's going to have success for a while. 

I hope the expectations don't go back to budding superstar and people appreciate what they have. Also, I don't think a return to regular duty at third base is out of the question.

Wining is always good, however your team is doing!

[wesnewy]

Royce has a 1.000 OPS over his last 15 and almost .900 over the last 30 games. When he is at his best the Twins are winning games, and he is one of the true "vibes guy" for the team. I remember how fun it was when he was killing it in 2023 and I am starting to see that same guy again since he had the reality check in st paul earlier this season

[Jeff K]

His hitting is encouraging.  I also think that with experience, Royce can be an above average fielding first baseman.  I would 100% stop playing him at 2nd base and only in rare situations at 3rd base.  He is now the Twins 1st basemen unless the hitting stops.

This is very accurate. His swing is such that I think he will probably always be streaky but if he can manage more ups and fewer downs he will be productive. I especially agree that he still could end up at third base. Regardless he is playing a much more well rounded game. 

[sun]

I think that letting him hit higher up in the batting order gives him a better mindset and more confidence. The more that he enjoys himself the better he'll hit. For him the game is mostly in between his ears.

[gman]

I think the starting infield for most of next season is going to be Lewis 1B, Lee. 2B, Culpepper 3B and Houston at SS. I'd prefer that Lewis stayed at first base the rest of this year to get as much in game practice as possible.  Between Houston and Culpepper watching the majors and minors, Houston is pretty clearly the better shortstop and that may not be fair to Culpepper. It'll take the next year and a half to get a real good feel for how that infield is going together.

[BrainerdGuy]

I like your infield alignment for 2027 gman but I would place Culpepper at 2nd (keep him in the middle infield) and leave Lee at 3rd.  We might end up with one of the best up the middle defenses in the game (when is the last time a Twins fan could say that with a straight face?)!

[ashbury]

This discussion is timely in view of Lewis's 0-5 day today.

Ha. That typo seems like it should be more common in these threads than I recall!
