Boston Red Sox Have New No. 1 Overall Prospect

The 20-year-old has been incredible for the Red Sox organization down with Double-A Portland so far this season. Arias has played in 26 games and is slashing .366/.444/.699 with eight homers, 22 RBIs, 10 walks, seven doubles and 20 runs scored.

Arias can play both middle infield spots and also has gotten some playing time as Portland's designated hitter this season. It has been far and away the best season of his professional career to this point as well. In 2025, Arias hit eight homers, drove in 66 runs and slashed .278/.335/.388 in 116 games played. In 2024, he hit nine homers, drove in 54 runs, stole 35 bases and slashed .309/.409/.487 in 87 games played.

The biggest difference in 2026 has been Arias' power. That's the one area of his game offensively that hadn't really fully come together yet. Now, he looks like a threat all over and is just two steps away from the big leagues.

Plus, he's just 20 years old. There's a world in which Marcelo Mayer and Arias could be the middle infield of the future for Boston, unless the club makes some sort of trade. Arias joins a long line of former top prospects for the organization. Tolle had the title for a very brief time. Last year, Roman Anthony held it for a while. There was a chunk of time in which the title belonged to Mayer. Now, it's Arias' and he's certainly plenty like he's worth of the top spot.

If Arias keeps playing like he has to begin the season, he should be in line for a promotion to Triple-A Worcester soon. Then, it's all about opportunity. If Arias plays well and some sort of injury pops up, maybe we could even see him in Boston this year. That's thinking a bit ahead, but he's another prospect fans should be very happy about.
