Lance Lynn and the White Sox agreed to a two-year, $38 million extension just days after the right-hander's first All-Star appearance in nearly a decade.
The right-handed pitcher will receive $18.5 million each of the next two seasons while the club holds an $18 million option for 2024 with a $1 million buyout.
The 34-year-old, who pitched the second inning of Tuesday's American League win, is currently 9-3 with a 1.99 ERA and 105 strikeouts over 16 starts this season. Lynn was set to be a free agent this offseason after joining Chicago in December following a trade with Texas.
