Campbell was removed from Triple-A Worcester's game Wednesday versus Syracuse after feeling a spasm in his left shoulder while running the bases, Tommy Cassell of the Worcester Telegram & Gazette reports. He was later diagnosed with left lat soreness, according to Alex Speier of The Boston Globe.
Worcester manager Chad Tracy said he's unsure if Campbell will be able to play Thursday, but the lat injury is considered "very minor" and isn't expected to keep the infield prospect out for the season. The 22-year-old's prospect stock has gained plenty of helium during a banner 2024 campaign in which he's slashed .330/.439/.558 with 20 home runs and 24 stolen bases in 519 plate appearances across three levels.
