Arizona Diamondbacks infielder Demetrio Crisantes has emerged as a prime candidate for a September roster promotion as Major League Baseball organizations navigate late-season call-ups and upcoming roster crunches. The 21-year-old infielder has forced his way into the major league conversation following a dominant offensive stretch in Double-A and an assignment to Triple-A.
Crisantes primarily plays second base and third base, positions currently anchored at the major league level by Ketel Marte and Nolan Arenado for Arizona. Despite the positional logjam, his elite bat-to-ball skills and high contact rates in the minor leagues have set him apart from other upper-level prospects. His offensive profile makes him a compelling option for a club needing late-season bench depth during a competitive Wild Card race.
The 40-Man Roster Crunch and Rule 5 Eligibility
A driving factor behind a potential major league look for Crisantes involves the upcoming offseason Rule 5 Draft. Crisantes is eligible for selection in the Rule 5 Draft this coming winter unless the Diamondbacks add him to their 40-man roster. Adding him in September allows the front office to evaluate his capabilities against major league pitching before making a definitive 40-man roster decision.
Historically, front offices use the final month of the regular season to test internal depth pieces under major league game conditions. While Crisantes has seen limited action at first base in the minor leagues to increase his defensive versatility, his bat remains his carrying tool. His ability to consistently barrel baseballs and limit strikeouts in Double-A served as the primary catalyst for his promotion to Triple-A.
Evaluating September Call-Up Strategies in MLB
September roster expansions provide a structured window for franchises to balance immediate postseason pushes with long-term evaluation. Teams frequently promote top prospects not only to inject energy into active lineups but also to gather baseline performance data heading into winter workouts and trade discussions. For Arizona, weighing Crisantes’ minor league track record against immediate major league needs highlights the delicate balance between preserving long-term prospect value and capitalizing on roster flexibility.
As the minor league season concludes and major league rosters adapt to September thresholds, the Diamondbacks face a definitive deadline on evaluating whether Crisantes fits into their immediate major league calculus or requires protected roster status to prevent losing him to another franchise.
