The Red Sox parted ways with infielder Vaughn Grissom on Tuesday by sending him to the Angels in a minor trade.
In exchange for Grissom, Boston simultaneously opened a 40-man roster spot ahead of Wednesday’s Rule 5 Draft and acquired outfield prospect Isaiah Jackson from Los Angeles.
Jackson, 21, was originally taken by the Astros in the 18th round of the 2022 draft out of Cienega High School in Arizona. Rather than enter the professional ranks at that time, though, the Vail, Ariz. native elected to honor his commitment to Arizona State. He played three seasons with the Sun Devils and batted .310/.402/.630 with 11 doubles, two triples, 18 home runs, 68 RBIs, 51 runs scored, 14 stolen bases, 28 walks, and 43 strikeouts in 60 games (251 plate appearances) as a junior this past spring en route to earning All-Big 12 First Team honors.
Coming off a standout junior season, Jackson was ranked as Baseball America’s No. 179 prospect in the 2025 draft class. This time around, the left-handed hitter was selected by the Angels in the eighth round (229th overall) of July’s draft and signed for an over-slot $297,500. He made his professional debut with Los Angeles’ High-A affiliate in early August and appeared in 10 games for the Tri-City Dust Devils, going 7-for-32 (.219) with one double, one home run, four RBIs, six runs scored, four walks, and 13 strikeouts. Defensively, he made nine starts in center field and did not commit an error in 81 innings there.
Before Tuesday’s trade, Jackson was slated to enter 2026 as Baseball America’s No. 25 Angels prospect. The publication notes that the 6-foot-3, 220-pounder is “a well-built left-handed-hitting center fielder who is a plus defender despite only average speed,” adding that “he has the bat speed to have solid power with a swing geared especially toward pullside damage, but there are some questions about how well he will hit against more advanced pitching, especially against breaking balls.”
Jackson, who turns 22 in May, becomes the latest 2025 draftee to be added by the Red Sox via trade in recent weeks, joining the likes of Luke Heyman (acquired from the Mariners) and Adonys Guzman (acquired from the Pirates). Barring another move, he appears likely to start the 2026 campaign at High-A Greenville.
