Can Consistency, Aggression Realize High-A Infielder Felnin Celesten’s Elite Ceiling for M’s?

EVERETT, Wash. - The word that kept escaping the lips of AquaSox coaches was perhaps the exact one that a 25-game hitting streak would evoke, or perhaps the opposite. But it was indeed consistency that Felnin Celesten’s coaches talked about and that the young infielder himself brought up as his guiding value. It’s something that he admires in his own baseball idol.

“Really, since I was little, Francisco Lindor was 100% my favorite player, and what I may be able to bring is the consistency, and the consistency that he has with both hands,” Celesten told Emerald City Spectrum. “But I do think that we’re each our own players, I am Felnin and he is Lindor, you know? But like I said, it’s the consistency.”

The switch-hitting shortstop has plenty to work on, but there are glimpses of a potential five-tool player in the way he has played for the High-A Everett AquaSox in 2026. Through Saturday’s game, Celesten has slashed .317/.430/.473 in 228 plate appearances. This production has been quite the leap from his 2025 season with the Low-A Modesto Nuts, even considering the hitter-friendly park Celesten now plays in. The Athletic’s Keith Law recently made a big swing by ranking him 17th all-MLB (gift article), putting him behind only Kade Anderson and Ryan Sloan in terms of Mariners prospects.
