The Red Sox have promoted power-hitting infield prospect Yoeilin Cespedes from High-A Greenville to Double-A Portland, as first reported by Andrew Parker of SoxProspects.com.
Cespedes is currently regarded as Boston’s No. 14 prospect by SoxProspects.com, while Baseball America and MLB Pipeline both rank him 16th. With 18 home runs this season, the 20-year-old slugger trails only No. 1 prospect and fellow infielder Franklin Arias (21) for the organizational lead.
In addition to crushing a team-leading 18 homers, Cespedes batted .249/.310/.477 (92 wRC+) with 57 RBIs, 58 runs scored, two stolen bases, 29 walks, and 94 strikeouts over 82 games (378 plate appearances) for Greenville this season. The right-handed hitter fared particularly well against lefties, slashing .328/.382/.590 in 68 plate appearances. He slashed .231/.294/.452 in 310 plate appearances against righties.
Among 68 qualified hitters in the hitter-friendly South Atlantic League entering play Saturday, Cespedes ranked 12th in isolated power (.228), 15th in slugging percentage, 18th in line-drive rate (24.7%), 30th in OPS (.787), and 33rd in batting average, according to FanGraphs.
Defensively, Cespedes split most of his playing time with Greenville between shortstop and second base. In 41 starts at short, the compact 5-foot-8, 181-pounder (listed height and weight) committed seven errors in 186 chances over 365 2/3 innings. In 31 starts at second, he committed five errors in 133 chances over 276 1/3 innings. He also made 10 starts at DH.
A native of the Dominican Republic, Cespedes originally signed with the Red Sox for $1.4 million as a highly-regarded international free agent in January 2023. In his professional debut that season, he earned Dominican Summer League All-Star honors and was recognized as Boston’s Latin Program Position Player of the Year. He then arrived stateside in 2024 and shined in the Florida Complex League before earning a late-June promotion to Low-A Salem.
Due to lingering soreness in his left hand, however, Cespedes did not make his full-season debut in 2024. Instead, he was diagnosed with a broken hamate bone that ultimately required season-ending surgery. He returned to action with Salem in 2025 and proved durable, playing in 110 of the team’s 130 games. That said, he did so while struggling to a .227/.292/.376 line with 10 home runs and 54 RBIs over 477 plate appearances.
Coming off a down year, Cespedes was identified by Baseball America as a potential bounce-back candidate entering 2026. He certainly came out of the gates firing, slashing .317/.365/.567 with 10 home runs and 34 RBIs over his first 42 games (200 plate appearances) for Greenville this season. Since the calendar flipped from May to June, however, he batted just .173/.247/.377 with eight homers and 23 RBIs across his last 40 games (178 plate appearances) before Saturday’s promotion.
Overall, it has very much been an up-and-down season for Cespedes, who is arriving in the upper minors a month-plus shy of his 21st birthday in early September. Assuming he is not traded between now and Monday’s deadline, he should provide Portland with additional power from the right side of the plate as well as middle infield depth.
