Vargas signed a minor-league contract with the Diamondbacks on Friday, Jon Heyman of the New York Post reports.
Vargas spent most of his time at Triple-A Reno this past season but still managed to appear in 38 games for the D-backs, during which he slashed .270/.292/.383 with 19 RBI and 12 runs scored. He'll officially return to the organization to begin the 2026 campaign, although he's expected to remain an organizational depth piece.
