Former MLBer Kyle Farnsworth is getting ripped for his take on Orioles outfielder Trey Mancini ... after the ex-pitcher called out the star's toughness in his first season back after battling cancer.
29-year-old Mancini -- who beat stage 3 colon cancer in September 2020 -- has played in 128 games during his miraculous comeback in 2021 ... but took Monday off after getting hit in the foot and experiencing some "general soreness."
While most people wouldn't care what the 43-93 Orioles are doing in September, Farnsworth was randomly pissed about Mancini sitting out .
