Ferriss' record in 1947 was 12–11. His arm troubles and asthma restricted him to only nine starts and 31 appearances in 1948, and four appearances in 1949. His final major league appearance was on Opening Day of the 1950 season, when he pitched only one inning. Ferriss compiled a career record of 65–30, and shares the MLB record for consecutive home wins to start a season (13, in 1946). He was inducted into the Boston Red Sox Hall of Fame in 2002.
