BA Grade/Risk: 55/Extreme

Track Record: Arroyo spent most of his youth representing Colombia at international tournaments across the globe, including in the United States, Panama, Mexico and the Bahamas, and established himself as one of the top players in the 2022 international class. The Mariners signed him on the first day of the 2022 signing period for $1.375 million, the largest bonus given to a Colombian amateur. Arroyo immediately impressed team officials when he reported to the Mariners' Dominican complex and continued to stand out in his pro debut in the Dominican Summer League. He hit a team-best .314 and had nearly as many walks (27) as strikeouts (33).

Scouting Report: Arroyo is an exceptionally mature hitter for his age. He has a preternatural feel for the strike zone, is extremely disciplined and quickly adjusts to different velocities and pitch types. He rarely chases out of the zone and does a good job of identifying pitches to drive. Arroyo has quick hands and generates a lot of contact with a short, direct swing from the right side. He can manipulate the barrel and covers the entire plate, giving opponents few zones to attack and helping him project to be a plus hitter. Arroyo doesn't hit the ball overly hard, but he has room to get stronger and his balls carry well off the barrel. Arroyo is firmly a bat-first player. He is a shortstop now, but he's an average runner with fringy range who will be stretched at the position as he matures. He is a reliable defender with solid hands and an average arm and should be an average defensive second baseman.

The Future: Arroyo's swing mechanics and overall skill set draw frequent comparisons with Howie Kendrick. He projects to be a similarly contact-driven second baseman and will make his U.S. debut in the Arizona Complex League in 2023.
