The Chicago White Sox and veteran left-hander Martin Perez are in agreement on a one-year deal worth $5 million, a source told ESPN amid multiple reports Wednesday. Perez, 33, went 5-6 with a 4.53 ERA in 26 starts with the Pittsburgh Pirates and San Diego Padres in 2024.

The White Sox and left-hander Martin Perez are in agreement on a deal, reports Robert Murray of FanSided . It’s a one-year, $5M deal, per Jose F. Rivera of ESPN. That comes in the form of a $3.5M salary and a $1.5M buyout on a $10M mutual option for 2026, per Jon Heyman of The New York Post. The deal is pending a physical for the Octagon client.

That’s somewhat encouraging but Pérez has previously flashed better results without sustaining them. He posted a 2.89 ERA over 32 starts for the Rangers in 2022, which prompted Texas to issue him a $19.

Former Red Sox slugger Bobby Dalbec and the White Sox are reportedly in agreement on a contract ahead of the 2025 season.
