Chris Flexen agreed to a $1.75 million, one-year contract with the Chicago White Sox, giving manager Pedro Grifol another possibility for his rotation.
Flexen played for Seattle and Colorado this season, going 2-8 with a 6.86 ERA in 29 games, with 16 starts. The right-hander is 27-34 with a 4.95 ERA in 120 major league appearances, including 80 starts.
To clear a roster spot, Chicago designated catcher Carlos Perez for assignment on Saturday.
The 29-year-old Flexen had an $8 million salary last season. He was designated for assignment by the Mariners on June 27 and then traded to the New York Mets, who promptly designated him for assignment.
Flexen signed a minor league deal with Colorado and was recalled from Triple-A Albuquerque on July 29. He went 2-4 with a 6.27 ERA in 12 starts with the Rockies.
