Of all the Rule 5-grabbing and waiver wire-pouncing and free agent bargain bin-diving the White Sox have done this offseason, the biggest paycheck will go to Martin Pérez, a journeyman lefty who has put the “eh?” in “meh.”
The 33-year old Pérez has been a very slightly below-average starter both recently (4.53 ERA for a 92 ERA+ in 2024) and through his career (4.44 ERA, 99 ERA+). He had a terrific year in 2022 (2.89 ERA, 137 ERA+ for the Texas Rangers), but has been on the wrong end of the aging curve since.
