Overview

• Kristian Campbell, Boston's rookie second baseman and a top prospect, has started training at first base following Triston Casas' season-ending knee injury.
• Manager Alex Cora outlined a structured evaluation process for Campbell's transition, estimating it could take between 10 days and two months.
• Initial replacement Romy Gonzalez, currently on the 10-day injured list with a quad contusion, is expected to return by early next week.
• Star slugger Rafael Devers declined a positional shift to first base, limiting Boston's options for filling the vacancy.
• Campbell, who has experience at multiple positions but none at first base, is seen as a key part of Boston's long-term development strategy.
