SCOTTSDALE – The Arizona Diamondbacks' farm system is very strong with up-the-middle infielders. Among them is Jansel Luis, who played the 2025 season with their High-A affiliate in Hillsboro.

Luis is coming off a strong season, in which he batted .304 with 21 doubles, seven triples, five home runs, and a 106 wRC+ in 102 games. Among 20-year-olds at the level, his wRC+ ranked fifth amongst players who logged 250 at-bats.

"I just want to thank God for a positive season," said Luis through pitching coach Tyler Mark, who served as the translator. "I just want to keep working on my approach here, and just keeping going from here, making better swing decisions."

Luis missed three weeks of the season due to injury. To make up for those lost reps, the D-backs sent him to compete in the Arizona Fall League.

With fellow infield prospect Cristofer Torin manning short for Hillsboro, Luis played primarily at second base. By starts, it was 51 at second, 18 at short, and 26 at third. The switch to second was mostly triggered by a season-ending shoulder injury to Demetrio Crisantes in May.

In the fall league, he started at third base on Tuesday and shortstop on Wednesday.

"Just develop playing second base, getting used to third and short. Second base obviously has a shorter throw, third base has got to be a little bit more prepared.

"I'm feeling comfortable, just getting more reps at the different spots and different angles. I'm feeling comfortable, I think I'm going to keep getting better with more reps at each position."

Adding more spots he can play on the infield will help in his climb to the big leagues. The D-backs have established veterans at second base and shortstop in Ketel Marte and Geraldo Perdomo. Third base is still unsettled, but they have a couple options between Blaze Alexander and Jordan Lawlar.

The organization has plenty of middle infield depth in its farm system, but most of them do not possess the overall upside that Luis does. Tommy Troy is knocking on the door and looking like a potential replacement for Marte at second. The organization also has Torin, Crisantes, and 2025 first-rounder Kayson Cunningham among its top infield prospects.

At 20 years old, Luis is still very much a raw talent. FanGraphs' scouting report projects 60 raw power and 55 in-game power. He's already recorded an exit velocity reading of 109.2 MPH in the fall league. His physical development is very much on the same track as the D-backs' two starting middle infielders, so patience will be the key in his overall development as a player.

Finding a spot for Luis on the infield is likely a decision the team doesn't have to consider until after the 2026 season at the earliest. That's when he becomes Rule 5 eligible, and is almost certain to be a 40-man roster addition if healthy. His likely arrival time will come at some point during the 2027 season, but there are a lot of decisions the D-backs will have to make between now and then.
