Red Sox infield prospect Franklin Arias has the makings of a ‘true shortstop’

The Red Sox had a number of young, international prospects make their respective professional debuts in the Dominican Summer League this past season, including infielder Franklin Arias.

Arias, who just turned 18 last month, signed with Boston for $525,000 coming out of Venezuela back in January. In May, Ben Badler of Baseball America noted that the Caracas native was a “high baseball IQ player with good rhythm at the plate” and “easy arm strength” on the field.

Nearly four months after putting pen to paper, Arias debuted for DSL Red Sox Red on June 18. The right-handed hitter immediately made his impact felt by going 4-for-5 out of the leadoff spot with two RBIs, one run scored, and one walk in an 11-9 victory over DSL Tigers 1.

Arias recorded two more four-hit games in June (the first of which he notched his first pro home run) before cooling off to the tune of a .191/.261/.262 slash line in 12 July contests. He then ended the year on a strong note by going 14-for-34 (.412) with five extra-base hits in August.

All told, Arias batted a stout .350/.440/.453 with nine doubles, one triple, one home run, 15 runs driven in, a team-high 32 runs scored, three stolen bases, 19 walks, and 14 strikeouts in 37 games (159 plate appearances) for Boston’s DSL Red affiliate. Going even deeper, Arias posted a 1.036 OPS against lefties and an .854 OPS against righties.

Among the 276 hitters in the Dominican Summer League who registered at least 150 plate appearances this season, Arias ranked fifth in strikeout rate (8.8 percent), fourth in batting average, 24th in on-base percentage, 57th in slugging percentage, 37th in OPS (.893), 57th in line-drive rate (23.3 percent), 12th in swinging-strike rate (14.8 percent), and 33rd in wRC+ (144), per FanGraphs.

On the other side of the ball, Arias saw all of his playing time on the field this summer come at shortstop. The 5-foot-11, 170-pounder logged a team-leading 260 1/3 innings at the position, committing nine errors in 121 chances (.926 fielding percentage) while also turning 16 double plays.

Arias, who was not ranked by SoxProspects.com at the start of the minor-league season in April, is now regarded by the site as the No. 30 prospect in Boston’s farm system. Similarly enough, MLB Pipeline currently has Arias ranked 28th on its Red Sox-centered top prospects list.

The Boston Globe’s Alex Speier, who compiles the Red Sox’ organizational rankings for Baseball America, unsurprisingly excluded Arias from his preseason top-10 list heading into 2024. He did, however, have encouraging things to say about Arias in a virtual chat with BA subscribers on Friday.

“Yeah, he’ll start to get attention next year,” Speier wrote of Arias. “There’s a strong consensus that he’s a true shortstop, with enough bat-to-ball that he should have some offensive value. His physical development will determine how much, but he has an unusually clear path to being a big-leaguer for someone who has yet to play in the United States.”

To that end, Arias is projected by SoxProspects.com to make the jump to the States and play in the rookie-level Florida Complex League next season. As things stand now, he would seemingly be in a competition for playing time at shortstop with top prospect and fellow 2023 international signee Yoeilin Cespedes.

Of course, the Red Sox will more than likely find a way to accommodate both infielders so they each get plenty of at-bats in Fort Myers. Still, this can be viewed as a good problem to have if it means one or both of Arias and Cespedes get exposure at a new position next year.
