Kristian Campbell struggles in Triple-A after data-driven swing changes

The Red Sox organization continues to monitor Kristian Campbell as the prospect remains in Triple-A Worcester. After signing an eight-year, $60 million extension in April 2025, Campbell struggled to maintain his early major-league performance. He hit.301 with an.902 OPS in his first 29 games but saw his production fall to a.159 average over his final 38 games before his demotion in June 2025. Team officials previously integrated Driveline Baseball hitting principles into his development to prioritize ball flight and bat speed. Trainers have attempted to refine his swing since his reassignment to the minors, yet he has not regained his initial form. Evaluators remain divided on whether internal tinkering or adjustments to specific pitch types like sinkers caused his decline.
