In a significant move ahead of the trade deadline, the Chicago White Sox have acquired three-time All-Star pitcher Luis Castillo from the Seattle Mariners. The trade, which sees the White Sox send three players including Seranthony Domínguez and prospects Boston Smith and Nolan Jones to Seattle, aims to bolster their rotation with the addition of the veteran right-hander. With this deal, the Mariners are making room in their roster and shedding salary, while the White Sox look to strengthen their pitching staff as they strive for a competitive edge.
