According to MLB.com's Ian Browne, Doerr was the oldest living Hall of Famer and former Red Sox player prior to his death.
Doerr spent his entire 14-year career with the Red Sox from 1937 through 1951, with the exception of 1945 when he served in World War II.
Playing only second base, Doerr was a .288 career hitter with 223 home runs, 1,247 RBI, 1,094 runs scored and 2,042 hits.
He was named an All-Star on nine occasions, including his penultimate season in 1950 when he hit .294 and reached career highs with 27 homers and 120 RBI.
Although he never won a World Series, Doerr hit .409 in the 1946 Fall Classic, which the St. Louis Cardinals won in seven games.
Following his playing career, Doerr served as a scout and eventually a first base coach for the Red Sox before he became the expansion Toronto Blue Jays' hitting coach in 1977, a position he stayed at until 1981.
Despite falling short of championship glory as a player, Doerr was elected to the Hall of Fame in 1986, and he received a World Series ring in 2004 when the Red Sox ended their title drought, per Browne.
