Is this Red Sox shortstop the next big thing, or just a work in progress? While a young phenom is making waves in the Red Sox system, questions linger about his ability to translate raw talent into consistent power. Baseball America has placed 20-year-old shortstop Franklin Arias as the No. 2 prospect within the Red Sox organization and even ranked him No. 49 on their prestigious Top 100 list. Meanwhile, the highly respected Keith Law over at The Athletic has him even higher, slotting Arias as the No. 12 overall prospect in all of baseball! That's some serious buzz for a player who's already showing off impressive skills.
But here's where it gets interesting: despite his high rankings, there are some whispers of concern. The main talking point? Whether Arias can consistently hit for extra-base power. While his range and arm are considered above average, and he boasts excellent bat-to-ball skills (evidenced by his .299 batting average and .377 on-base percentage over 240 minor league games), the slugging numbers haven't quite caught up yet. He finished the 2025 season with a .388 slugging percentage, a modest eight home runs, 27 doubles, and just one triple in 116 games. What's more, a significant 47.7% ground ball rate in his professional career suggests he might be leaving some potential power on the table.
And this is the part most people miss: the Red Sox have been actively working with Arias on two key areas to unlock his full potential. Firstly, they want him to focus on hitting the ball in the air more consistently, which involves adjusting his point of contact to be a bit further out in front of the plate. Secondly, and perhaps more tangibly, they asked him to add weight, and he's responded impressively! The 5-foot-11 shortstop, who weighed 170 pounds last season, proudly announced at the Red Sox Rookie Development Camp in January that he's now up to 179 pounds, a testament to his dedication to nutrition and weight training.
Arias himself acknowledges the importance of these adjustments. "That (point of contact more out in front) is one of the things I want to keep improving," he shared through a translator. "I’ve talked to them during the season and the offseason to try to improve that point of contact to put the ball in the air. I feel that’s going to be one of my main focuses in spring training." His former hitting coach, J.P. Fasone, who is now the organization's minor league hitting coordinator, elaborated, "He’s really good at letting the ball travel and taking his hits. But I think there’s more opportunities for him to kind of catch the ball out in front, hit the ball in the air a little bit more and pull it a little bit more. He tends to miss some pitches early in the count. I think as he continues to improve those pitches will get hit."
While these adjustments aren't drastic – Arias describes them as more "tweaks" – they have had an impact. His slugging percentage did dip from .446 in the first half to .331 in the second half last year. However, a strong finish in his 10 games at Portland, where he hit two homers and two doubles with a .435 slugging percentage, offers a glimpse of what's to come. One area that still needs work is his performance against left-handed pitchers. He's demonstrably better against righties, posting a .291/.343/.412/.755 line compared to a .235/.307/.313/.620 line against lefties in 2025. Arias is optimistic, though, stating, "I was able to see making those changes will lead to better results in terms of slugging."
The Red Sox also recently made a trade, acquiring pitcher Gage Ziehl from the White Sox in exchange for reliever Jordan Hicks and prospect David Sandlin. Ziehl, a 22-year-old right-hander, posted a 4.12 ERA and 1.26 WHIP in 22 outings in 2025. Baseball America grades his sweeper as 55 (above average), his cutter at 50 (major league average), and his curveball and changeup at 45 (fringe average), with his fastball at 40 (below average). His scouting report highlights his reliance on his sweeper and cutter, with his fastball being used sparingly.
In other roster news, the Red Sox signed catcher Matt Thaiss to a minor league deal with an invitation to big-league camp. Thaiss, who has played in 305 major league games, will compete with Connor Wong to be Carlos Narváez’s backup. He's a strong blocker but has concerns with arm strength and framing, though the team has shown they can help improve those areas.
Spring training is just around the corner, and the Red Sox have extended invitations to several minor league players to join the big league camp. These include a host of pitchers (both right and left-handed), catchers, infielders, and outfielders, giving them an opportunity to impress the coaching staff.
What do you think? Is Franklin Arias destined for stardom, or are the concerns about his power a sign of a player who might plateau? And how will the new additions like Gage Ziehl and Matt Thaiss impact the Red Sox's future? Let us know your thoughts in the comments below!
