Veteran left-hander Martin Perez has agreed to a one-year, guaranteed $5 million contract to return to the Boston Red Sox, a source confirmed to ESPN's Jeff Passan.
Perez's agreement, which was first reported by the Athletic, includes a club option for a second year for 2022.
The 29-year-old spent last season with the Red Sox, going 3-5 with a 4.50 ERA, after going 10-7 with a 5.12 ERA during the 2019 season with the Twins. He had spent the previous seven seasons with the Texas Rangers, posting double-digit wins three separate times.
