Sox roll the dice on Castillo, trading future depth for rotation upgrade

White Sox, acting as buyers, sent Seranthony Domínguez, Boston Smith and Nolan Jones to Seattle to acquire Luis Castillo, hoping for an immediate rotation upgrade in a tight market. Castillo carries a two-year, $45.5 million commitment (roughly $22.75M per year) and a 5.06 ERA this season, making the risk tangible; the deal could effectively become a one-year, about $10 million cost for 2027 if it pays off after offsetting Domínguez. The trade reflects a calculated push for the present in exchange for future depth, aided by earlier moves that added pitching upside, but it raises questions about long-term payroll and farm-system strength.
