The Reds selected Arroyo's contract from Double-A Chattanooga on Tuesday, Francys Romero of BeisbolFR.com reports.
Arroyo slashed .284/.345/.371 with three home runs and 12 stolen bases over 120 games with Chattanooga in 2025 after missing the 2024 campaign due to shoulder labrum surgery. The 22-year-old is now on the 40-man roster and could move up to Triple-A Louisville to begin the 2026 season.
