Four days after the Boston Red Soxsaid goodbye to Rafael Devers, the team is set to demote one of the prospects who was supposed to help replace him as a franchise player. Boston plans to option second baseman Kristian Campbell to Triple-A Worcester,according to MLB.com. The club has not confirmed the move but figures to do it Friday ahead of its game against Devers and the San Francisco Giants. The Red Sox signed Campbellto an eight-year, $60 million contract extension early in the season. Not much has gone according to plan this season for the 39-37 Red Sox, who made headlines earlier this week when they traded their longest tenured player, Devers, aftera simmering position dispute. Somehow, Campbell was a factor in Devers' unhappiness, withJoon Lee reporting for Yahoo Sportsthat Devers was upset when Campbell volunteered to cover first base for the Red Sox after Triston Casas tore his patellar tendon. Devers outright refused to switch positions after losing third base to offseason signee Alex Bregman, but he also reportedly interpreted Campbell's offer as a slight to his own stature. Campbell was one of three highly anticipated prospects Boston was expecting this season, alongside outfielder Roman Anthony and shortstop/third baseman Marcelo Mayer. All three players ranked in the top 15 of Baseball America's top prospects list, but only Campbell broke camp with the big-league club. As a prospect, the 22-year-old Campbell presented a well-rounded offensive approach combined with defensive versatility. He was an unheralded talent in the 2023 MLB Draft, with the Red Sox landing him in the fourth round, but he broke out in 2024, earning Baseball America's Minor League Player of the Year Award after hitting .330/.439/.558 between High-A, Double-A and Triple-A. For about a month this spring, Campbell delivered on the hype. He finished April hitting .301/.407/.495 and looked like a Rookie of the Year candidate, but then he fell off massively. He has hit .159/.243/.222 since the calendar turned to May, with only one base hit in the past week. While Campbell was scuffling, the Red Sox called up Anthony and Mayer. They had the trio together for a little more than a week but will now send Campbell down to work on his offensive approach and perhaps get his confidence back.
