D-backs Add Untapped Potential with Former Phillies Pitching Prospect

The Arizona Diamondbacks have made another addition to their minor league ranks.

According to the D-backs' transaction log page on MLB.com, Arizona has signed right-handed pitcher Gustavo De La Cruz to a minor league contract, backdated to an April 9 signing date.

De La Cruz is just 19 years old, and spent his time with the Phillies organization in their Dominican Summer League club. He is now set to join Arizona, likely in the same region of the organization, though that is not yet clear.

The Phillies signed De La Cruz as a 17-year-old back in 2024 out of the Dominican Republic. He's only pitched 21.1 innings in the DSL thus far in his young career, making four appearances in 2024 and 11 in 2025.

The 6-foot-3, 165-pound righty has mostly been used as a reliever, but he also did make three starts during the 2025 season. He owns a 7.17 ERA in a very limited sample size due to an immense walk problem.

Though De La Cruz has 21 strikeouts in his 21.1 career innings, he's also issued an astounding 40 walks in that span. He's only given up 16 hits (and zero homers) in his limited time in the DSL, but command is clearly an area that needs extreme development.

As is often the case, young international free agents can occasionally become eventual hidden gems, though that is nothing of a guarantee. The Diamondbacks clearly saw something in De La Cruz's abilities that they felt worthy of taking a flier on.

Regardless of talent, there is usually an extremely lengthy development pathway for players who are signed as teenagers. There have been exceptional success stories, of course, but results are not realized until years down the road, for the most part.

It may not end up being a move that amounts to anything, but there may be some untapped potential in De La Cruz.
