Red Sox decline to pick up 2021 contract option on Martin Perez

Martin Perez officially is a free agent, marking the end of his short tenure with the Boston Red Sox

The Red Sox announced Sunday they declined to pick up Perez's $6.25 million option for the 2021 season and instead bought him out for $500,000.

Perez was Boston's most reliable pitcher this past season, going 3-5 with a 4.50 ERA in 12 starts. He was relied more heavily upon than anticipated following Eduardo Rodriguez's COVID-19 diagnosis and Nathan Eovaldi's struggles with injury. 

Free agency began at 5 p.m. ET on Sunday. Red Sox slugger J.D. Martinez opted into his player option for 2021 while Jose Peraza elected for free agency.
