1. SS Franklin Arias | 20 | AA | 2027

Arias signed for $525,000 as the second highest paid player in Boston’s 2023 international class. Today, that looks like money well invested. A right-handed hitter listed at 5’11” 170 lbs, Arias wasn’t as good in 2025 as he had been the year before, but he was facing much older competition and still managed a 108 wRC+ in 87 High-A games despite slashing .265/.329/.380. The plate skills were still elite: 8.2% walk rate against an 8.9% strikeout rate, so the organization waved him along to Double-A for a ten-game stretch at season’s end. He hits the ball hard enough. Just needs to add some loft and grow into some man-strength.
