Boston Red Sox Reportedly Promote Top Prospect to Triple-A

There have been few prospects in baseball that have seen their stock rise as much this season as Boston Red Sox shortstop Franklin Arias has. In the span of months, he has become one of baseball's best prospects. 

The 20-year-old has dominated Double-A in 2026, hitting .318/.407/.587/.994 in 75 games for Portland. Heading into the season, Arias was seen as a glove-first prospect with a strong hit tool, whose ceiling would be determined by his ability to grow into power. Well, he has found that power stroke in a major way in his fourth season of professional play. After hitting just 18 home runs in his first three years, Arias has hit 19 in 2026.
