Here are three things well be paying attention to around baseball this Thursday: 1. Arbitration filing deadline: By noon CT this afternoon, all arbitration-eligible players must either agree on a contract for the 2025 season or both player and team must file for arbitration. The deadline for both sides to submit arbitration figures is later this evening at 7:00 PM CT. That means you can expect a significant number of players to sign their deals for the upcoming season today.

Another 40-man move incoming from the White Sox: The White Sox have already made a handful of 40-man roster moves in the past few weeks, such as DFAing , , and to make room for , , and , respectively. Soon, Chicago will have to make another transaction before finalizing the teams biggest (relatively speaking) offseason addition yet: . The veteran starting pitcher agreed to with the White Sox on Wednesday. Before officially announcing the deal, the club must open a space for Prez on the 40-man roster.
