The Red Sox have promoted outfield prospect Isaiah Jackson from High-A Greenville to Double-A Portland, as first reported by Beyond the Monster’s Hunter Noll.
Jackson is currently ranked by Baseball America as Boston’s No. 30 prospect. The 22-year-old is in his first full season, both in the organization and as a professional. He was originally selected by the Angels in the eighth round (229th overall) of the 2025 draft out of Arizona State, then acquired by the Red Sox for infielder Vaughn Grissom in December.
An Arizona native himself, Jackson earned 2023 and 2024 Pac-12 All-Defensive Team and 2025 All-Big 12 First Team honors before signing with the Angels for $297,500 last July. He made his pro debut with High-A Tri-City, playing 10 games there. After being traded to the Red Sox, he remained at the High-A level to begin this spring, breaking camp with Greenville.
Though he got off to somewhat of a slow start, Jackson turned a corner in July and ended up putting together a productive season for the Drive, particularly in the power department. The left-handed hitter batted .243/.340/.465 with 18 doubles, two triples, a team-leading 21 home runs, 69 RBIs, 68 runs scored, 10 stolen bases, 49 walks, and 105 strikeouts over 102 games (444 plate appearances). He slashed .252/.343/.482 in 356 plate appearances against righties and .203/.330/.392 in 88 plate appearances against lefties.
Among 57 qualified hitters in the South Atlantic League this season, Jackson notably ranked ninth in isolated power (.222), 11th in line-drive rate (25.9%), 13th in slugging percentage, 20th in OPS (.805), 24th in wOBA (.358), and 25th in wRC+ (103), according to FanGraphs.
Defensively, Jackson saw playing time at all three outfield spots with Greenville. The athletic 6-foot-3, 220-pounder made 53 starts in center field, 31 starts in right field, and 14 starts in left field, committing five errors and recording six assists in 194 total chances. He also made two starts at DH.
Jackson, who does not turn 23 until next May, will get the opportunity to finish the 2026 campaign in the upper minors with Portland. The Sea Dogs have six games against Binghamton at Hadlock Field remaining on their schedule and currently sit 4 1/2 games back of a playoff spot. Unless a miracle occurs, their season will end on Sunday.
Barring his involvement in a trade or other move this winter, Jackson is projected by SoxProspects.com to return to Portland in 2027. This late-season promotion, then, gives him something of a head start in getting a feel for the Double-A level.
