The Chicago White Sox have bolstered their pitching staff by signing left-handed pitcher Martin Perez to a one-year deal, pending a physical examination. Perez, who spent time with both Pittsburgh and San Diego last season, recorded a 5-6 record and a 4.53 ERA over 26 starts. In his career, he has made 314 major league appearances, with a 90-87 record and a 4.44 ERA.

Last season, Perez faced challenges, including a stint on the injured list due to a groin strain, but he closed the season strong with a 3-1 record and a 3.46 ERA in his final ten starts with the Padres. The White Sox, coming off a dismal 2024 season with a record of 41-121, are looking for a turnaround.

Additionally, infielder Josh Rojas has joined the team with a one-year, $3.5 million contract, while Jake Amaya has been designated for assignment. Rojas struggled last season with the Mariners, hitting .225 with eight home runs and 31 RBIs. The White Sox also made roster adjustments, assigning outfielder Corey Julks to Triple-A Charlotte and claiming infielder Braden Shewmake off waivers from the Kansas City Royals.

The Chicago White Sox have bolstered their pitching rotation by signing left-handed starter Martín Pérez to a one-year contract. The deal, which is subject to a physical, comes as the team aims to improve after a challenging 2024 season where they set a major league record with 121 losses.

Pérez, who spent last season with the Pittsburgh Pirates and San Diego Padres, finished the year with a 5-6 record and a 4.53 ERA over 26 starts. The 33-year-old has a career record of 90-87 with a 4.44 ERA in 314 appearances, including 269 starts.

After recovering from a left groin strain that sidelined him for roughly a month, Pérez closed out his tenure with Pittsburgh strongly, allowing no runs in his final start before being traded to San Diego. He made a positive impact for the Padres, securing a 3-1 record and a 3.46 ERA in his last ten starts, though he did not participate in the postseason.

In addition to signing Pérez, the White Sox also finalized a $3.5 million, one-year deal with infielder Josh Rojas, who had a blend of power and speed with eight homers and ten steals in 143 games for Seattle last season. Meanwhile, infielder Jake Amaya was designated for assignment as part of the team's roster adjustments.

The Chicago White Sox have strengthened their bullpen by acquiring reliever Cam Booser from the Boston Red Sox in exchange for minor league pitcher Yhoiker Fajardo.

Booser had a solid first season in the majors, achieving a 3.38 ERA and earning the Tony Conigliaro Award for his resilience through personal challenges.

In a corresponding move, the White Sox designated outfielder Corey Julks for assignment to clear space on their roster.
