Red Sox promote top prospect Franklin Arias to Double-A Portland

The Red Sox have promoted top prospect Franklin Arias from High-A Greenville to Double-A Portland, according to the club’s MiLB.com transactions log.

Arias is moving up a level for the second time this season. The 19-year-old infielder opened the 2025 campaign at Low-A Salem and batted .346/.407/.397 (134 wRC+) with four doubles, nine RBIs, 15 runs scored, four stolen bases, six walks, and 12 strikeouts in 19 games (86 plate appearances) before receiving a promotion to Greenville in late April.

After getting off to a blistering start with Greenville that saw him net South Atlantic League Player of the Month honors for May, Arias began to cool off as spring turned to summer. The right-handed hitter continued to struggle offensively out of the All-Star break in July, but has fared relatively better as of late to bring his line up to .265/.329/.380 (107 wRC+) with 21 doubles, one triple, six home runs, 49 RBIs, 43 runs scored, seven stolen bases, 32 walks, and 35 strikeouts in 87 games (392 plate appearances) for the Drive.

Overall, Arias is slashing .279/.343/.383 (112 wRC+) with 25 doubles, one triple, six home runs, 58 RBIs, 58 runs scored, 11 stolen bases, 38 walks, and 47 strikeouts in 106 games (478 plate appearances) between Salem and Greenville this season. That includes a .214/.296/.282 line against lefties and a .300/.358/.415 line against righties.

Between his stops in Salem and Greenville, Arias primarily split his playing time between shortstop and second base, logging 780 2/3 innings at the former and 44 innings at the latter. The rangy 5-foot-11, 170-pounder (listed height and weight) committed six errors (all at shortstop) in 364 total defensive chances. He also made 10 starts at DH.

A native of Venezuela, Arias originally signed with the Red Sox for $525,000 as an international free agent coming out of Caracas in January 2023. Lauded for his ability to make contact and fielding prowess, he made his professional debut in the Dominican Summer League shortly thereafter. He impressed there before truly breaking out last season. As part of a standout 2024 campaign, he was recognized as a Baseball America Rookie and Florida Complex League All-Star, the Florida Complex League’s Top MLB Prospect and MVP, and Boston’s Minor League Baserunner of the Year.

Unsurprisingly, Arias was included in multiple top 100 prospects lists to begin the 2025 season. He is currently regarded by Baseball America as Boston’s No. 3 prospect and the game’s No. 50 prospect, while MLB Pipeline has him ranked as Boston’s No. 1 prospect and the No. 24 prospect in the sport. SoxProspects.com has him at No. 2 on its top 60 list behind only rookie left-hander Payton Tolle.

Arias, who turns 20 in November, is leading off and starting at shortstop in Portland’s series opener against Erie at Hadlock Field on Tuesday night. The Sea Dogs have 12 regular-season games remaining and currently trail Somerset by just 1 1/2 games for a spot in the Eastern League playoffs.
