Rick Ferrell: 1933-1937
Ferrell played the fewest games of any catcher on this list at 522 but left his mark in the short time he was a member of the Red Sox. Acquired from the St. Louis Browns in 1933, Ferrell was selected to start for the American League in the inaugural MLB All-Star Game that year. He would hit .297/.385/.382 in 118 games with the Red Sox that season as well as a career-high 72 RBI.
Inducted into the Baseball Hall of Fame in 1984 with a Red Sox cap on his plaque, Ferrell was an all-star in all five seasons he spent with the team. During his time in Boston, he set franchise catching records in batting average, doubles, home runs and RBI. His career .378 on-base percentage ranks eighth all-time among catchers with at least 3,000 at-bats.
Known for more than his offense, Ferrell threw out 51% of runners while a member of the Red Sox and led all American League catchers with a .990 fielding percentage in 1934.
Despite playing just five seasons with the team, his 10.6 fWAR ranks fourth among all Red Sox Catchers.
