Introduction
For no particular reason, and definitelynot in light of any recent events involving the Diamondbacks, I thought it might be a good idea to examine a few of the middle infielders in the Arizona farm system, specifically second baseman. In this article I’m going to go into the middle infield prospects that stood out for various reasons.
The Omissions
There are two glaring omissions that are very close to the major leagues that I didn’t include in this writeup, only because each got their own dedicated article that I’ve put out in the last couple months. If not for that fact, Demetrio Crisantes and Danny Serretti would have their own section spotlighting them here in the ‘top prospects’ section. Crisantes is the team’s de facto top prospect overal, and the heir apparent at second base. He’s likely a year away from being ready at the earliest, while Serretti is a AAA Rule 5 guy who’ll need to be put on the 40 man roster at the end of the season if the Dbacks don’t want to see him taken in the MLB portion of the Rule 5 draft this winter.
Although I’ll still use this as an opportunity to give a quick update on both players, you can read my article on Demetrio Crisantes here, and my article on Danny Serretti here. Crisantes has gotten off to a slow start since his promotion to AAA Reno. He has 29 hits (including 5 doubles, a triple, and HRs) in 110 plate appearances, with 5 walks and 22 strikeouts. That translates to a triple slash line of 264/.299/.355 which works out to just a 52 wRC+ along with a .298 wOBA. His .232 xwOBA shows he’s probably been a bit lucky to even put up those meager numhers.
Meanwhile, Danny Serretti spent a couple months in Reno with an OPS above 1.000 at the end of July. Serretti began slumping over the following three weeks, with his statistics dropping down to a (still good) .934 OPS by August 18th, when he was sent back to AA Amarillo, although not for perfomance related reasons. Serretti currently has a .924 OPS in AA Amarillo.
The Top Prospects
John Samuel “JD” Dix (FG| B-Ref )
Bats/Throws: Switch/Right Height/Weight 6’2″ / 190 DOB: 10/12/2005 in Chicago, IL
Tools: Hit: 55. Power: 50. Run: 50. Field: 50. Arm: 50
Drafted in the Competive Balance-A round (35th overall) by the Arizona Diamondbacks in the 2024 draft, JD Dix signed for $2,150,000. Dix was the top prospect out of the state of Wisconsin in that 2024 draft class, attending the same Whitefish Bay HS that Dbacks 2001 World series alumni Craig Counsell attended.
Dix made his debut the following year in the Arizona Complex League. In 39 games for the ACL Dbacks, Dix had 178 plate appearences, hitting .342/.421/.493 with a .427 wOBA and 142 wRC+.Dix would get a promotion to the A ball level Visalia Rawhide, where he’d spend the remaining 50 games of his 2025 season. In 230 plate appearances for the Rawhide, Dix hit .261/.391/.335 with a .368 wOBA and 114 wRC+.
Overall, in the 89 games and 408 plate appearances total between the rookie level Arizona Complex League and the A Ball level California League in 2025, Dix hit .297/.404/.406 with 2 HRs, 29sb .394 wOBA 126 wRC+. 14.2% bb% 20.8% strikeout percentage.
I’ve embedded a video below of an interview that Visalia Rawhide posted to their official channel.
Dix began his season back in the California league to start the 2026 season. In 48 games, Dix received 235 plate appearances, hitting .253/378/.468 with a .382 wOBA and a 116 wRC+. At first glance those numbers don’t look like much of an improvement outside of the better wOBA and wRC+, Dix had a slightly worse walk percentage and strikeout percentage, he had much worse luck with a Batting Average on Balls In Play (BABIP) that was .052 lower.
The real improvement though was reflected in JD’s power: He had the same amount of triples, but hit three more doubles and seven more homers in two fewer games, which resulted in Dix’s isolated slugging percentage (ISO) having a massive surge from .074 to .216. In addition, Dix stole just as many bases (19) but was caught stealing only once, as opposed to four times the year before.
The Dbacks promoted JD to the A+ level Hillsboro Hops in the much less hitter friendly Northwestern League, where he’s had a much tougher time. In 48 games, Dix has recieved 212 plate appearences, hitting .245/.325/.351 .314 wOBA with an 80 wRC+. His power outburst slowed down, with only a pair of homeruns. He’s continued to be a burner on the basepaths, stealing 16 bases so far. However, he hasn’t been quite as successful with Dix getting caught stealing four times. Weirdly Dix has managed six more singles and three more triples than he had in Visalia.
The defensive picture is a lot more opaque compared to the offensive side of his game. Lingering effects from a labrum injury in highschool rendering his right arm strength too weak for him to play shortstop, however, Dix was put on an arm strength program over the last offseason. I have not heard much in the ways of his current arm strength, so someone in the comment section can hopefully chime in, since as far as I can tell, Dix has only played seven innings at shortstop in the complex league last year. This season he’s played all but 10 innings at second base, with those appearances coming at designated hitter.
Carson Kerce (FG | B-Ref )
Bats/Throws: Right Height/Weight 5’11 / 200lbs Born: 11/29/2004 in Atlanta, GA
Scouting Grades: Hit: 50 | Power: 40 | Speed: 55 | Field: 45 | Arm: 50
Drafted in the 2nd round of the 2026 draft with the 53rd overall pick by the Diamondbacks, Kerce essentially went from an afterthought in a potent Georgia Tech lineup his freshman year, to an offensive force as a leadoff hitter by his junior year, his last season going professional.
You can easily see the progress Kerce made year to year just looking at his wOBA and wRC+ statistics. Kerce put up a below average .360 wOBA and a 79 wRC+ his freshman season, improved to a slightly above average .403 wOBA and 103 wRC+ his sophomore season, before breaking out as a hitter with a robust .497 wOBA and 148 wRC+ his junior season. He also cut his strikeout percentage from 22% down to 15.2%, then even further to 13.3% in that same time span. Below I’ve embedded a video featuring highlights from Kerce’s time with Georgia Tech.
Kerce has played in 15 games with the Visalia Rawhide, and has 17 hits in 69 plate appearences, with three doubles, a HR, and 10 walks and two HBP. That works out to a triple slash line of .298/.420/.404, with a .393 wOBA and a 122 wRC+. He’s stolen five bases successfully in six attempts as well.
Kayson Cunningham (FG | B-Ref )
Bats/Throws: Left/Right Height/Weight: 5’10/182lbs Born: 6/25/2006 in Tucson, Az
Scouting Grades: Hit: 60+ | Power: 45 | Run: 55 | Field: 50 | Arm: 50
When I last talked about the Dbacks 2025 first round pick, Cunningham had demolished the California League. In 43 games he hit .381/.471/.506 with a .451 wOBA and 157 wRC+. He showed excellent plate discipline with 30 walks (14.5 bb%) to his 38 strikeouts (18.4 SO%). I’ve embedded a video below with highlights from the first half of season prior to his promotion.
The Dbacks promoted Cunningham to the A+ level Hillsboro Hops on June 9th, and the new level and league has proven to be much more of a challenge. In 53 games with the Hops, Cunningham is hitting .246/.360/.382 with a .344wOBA and a 98 wRC+. While he’s seen a slight uptick in his walk percentage by .01% to 14.6%, he’s also seen his strikeout percentage jump from 18.4% to 22.2%. Some of that decline in numbers may just be the result of his luck changing. In Visalia, Cunningham had an unsustainable .482 BABIP, while in Hillsboro it has swung back in the other direction to a .310 BABIP. He hasn’t been unlucky necessarily, just not as lucky.
Cunningham has an argument for being the best pure hitter in the Diamondbacks farm system, or at least in my opinion, the potential to be the best pure hitter in the system once he develops more as a hitter. (I’d argue right now that the best pure hitter is Demetrio Crisantes, with Cunningham a tic behind, mostly as a result of the former being further along in his development) Cunningham has played shortstop or designated hitter exclusively, and he certainly has the tools to stick at the position. However, I wouldn’t be surprised if he ends up at second base, third base, or somewhere in the outfield potentially.
The Underperforming but still young prospects
Not only were Jansel Luis and Cristofer Torin were signed as amateur international free agents signed in January of 2022, but both players have had their prospect stock fall in 2026 thanks to having bad seasons playing in the most hitter friendly ballpark in the already very hitter friendly Texas League. I have seen comments here on the Snakepit and on the Azdiamondbacks sub-reddit writing off both players’ status as prospects, with some even going so far as to label them busts.
Jansel Luis (FG| B-Ref )
Bats/Throws: Switch/Right Height/Weight 6’0 / 170lbs Born: 3/6/2005 in San Pedro de Macoris, DR
Scouting Grades: Hit: 50 | Power: 45 | Run: 50 | Field: 50 | Arm: 50
Jansel Luis is coming off an impressive season playing for the Hillsboro Hops in the Northwestern League. In 102 games played in a pitcher friendly ballpark, in a pitcher friendly league, he hit .304/.342/.422 with a .346 wOBA and a 106 wRC. Add in the four games played in the ACL, and that bumps his numbers up to .311/.347/.435 with a .353 wOBA and a 110 wRC+.
So with Luis headed to a hitter friendly ballpark, in a hitter friendly league, his underwhelming 2026 season is much more disappointing. Through his first 108 games in 2026, Luis has hit .270/.315/.445 with a .336 wOBA and a 78 wRC+. Though his walk percentage has dipped down from 6.0% to 5.0%, his strikeout percentage has shown a much more signifant increase from 16.3% to 25.1%. That’s right at the edge of still being acceptable, any worse and it’s a major red flag going forward. In general, the lack of walks combined with too many strikeouts are always a recipe for failure, and that combined with an erratic approach at the plate have been noted by other prospect evaluators as major red flags.
I wouldn’t write Jansel Luis off just yet, he’s still below the league average in age, and he’s got impressive tools all around. Jansel’s biggest weakness is his propensity for aggression at the plate, swinging too often at pitches he has no business trying to hit. That said, he’ll need to tone down the aggression and become more selective ar the plate to get back on track down the stretch, and he’ll need put up above average numbers in AA in his next season.
Primarily a shortstop and second baseman in the past, Luis has not played at second base in 2026. Instead, he’s now seen more time at third base instead, though he is still getting starts at short as well as DH on occasion. Some scouts think he’d be better off in outfield position, but the Dbacks have not played him at all in the outfield, at least in-game.
Cristofer Torin (FG | B-Ref)
Bats/Throws: Right Height/Weight 5’10/155lbs Born: 5/26/2005 in Acarigua, Venezuela
Scouting Grades: Hit: 45 | Power: 30 | Run: 40 | Field: 60 | Arm: 60
Torin had solid 2024 season in his second go around in A ball level Visalia, hitting .255/.381/.344 with a .360 wOB and a 106 wRC+ in 108 games. He followed that up with a breakout 2025 season for the A+ level Hillsboro Hops, hitting .287/.381/.385 with a .360 wOBA and a 115 wRC+ in 122 games. He then had an impressive cup of coffee with AA Amarillo to end his 2025 season, getting eight hits with four of those being doubles, a stolen base, and three walks in 25 plate appearences. That works out to triple slash of .381/.440/.571 with a .449 wOBA and a 159 wRC+.
Considering all of that, Torin’s 2026 season in AA Amarillo has proven to be extra disappointing, much like Jansel Luis’ 2026 season. In 102 games and 476 plate appearences, Torin is hitting a very meager .270/.335/.418 with a .337 wOBA and a 79 wRC+.
Probably the most interesting fact about his season is that while his walk percentage has dropped from 12.1% to 8%, his strikeout percentage has improved from 14.3% to 11.1%. In addition, he’s hit four triples and twelve homeruns, career highs in both, the latter being more than the previous two seasons combined.
Torin is an impressive defender at shortstop, enough so that he really doesn’t need to hit all that much to be a positive contributor in the major leagues. He’s always had an impressive ability to limit his strikeouts, while also drawing walks at a fairly impressive rate. Prior to this season he had only one season where he walked less than a 12% of the time, 9% in A ball in 2024. Considering Torin has needed a second try at a level in the pasr, it’s not surprising he’s struggled making the second hardest jump in professional baseball. If he struggles in his next try at AA, then I would start writing him off as prospect. As I stated with Jansel Luis, he’s still young for the level, so it’s not that big of deal if he’s back in AA next season.
Promising Start, but Too Young to Worry About
Leonardo Sivilla (FG|B-Ref)
Bats/Throws: Switch/Right Height/Weight 5’10/180lbs Born: 12/17/2007 in Santa Clara, Cuba
Scouting Grades: Hit: 55 | Power: 45 | Run: 70 | Field: 45 | Arm: 50
Sevilla signed for $750,000 on January 15th of 2026. He’s had a solid debut in the Domincan Summer league, hitting .293/.435/.395 with a 106 wRC+ in his first 53 games. Sevilla definitely lives up to that 70 grade speed, as he’s stolen 29 bases, though he has been caught seven times.
There’s not much else to say about Sevilla just yet as he’s likely three to four years away, he’s worth mentioning as a player expected to move through the farm system quickly, and for having all of his tools grade out as above average.
