Hooper was often known for his defensive skills, and he was among the league leaders in defensive categories such as putouts by a right fielder. During several seasons with Boston, he teamed up with Duffy Lewis and Tris Speaker to form the Golden Outfield, one of the best outfield trios in baseball history. Hooper is also one of only two members of four separate Red Sox World Series championship teams (1912, 1915, 1916, 1918). He was elected to the Baseball Hall of Fame in 1971.
