I came across this picture of Nellie Fox as coach for the Senators standing next to Frank Howard and thought it needed to be shared. Baseball-Reference has Nellie listed as 5'10" 160lbs (a bit generous) and Hondo at 6'7" 255lbs. Even with Fox standing on first base, Howard dwarfs him.
Nellie Fox's last Topps card showed him as "2nd Base-Coach" for the Astros in 1965. Although he played his last game in 1965 he continued as coach for the Astros through the 1967 season. He coached the Senators from 1968-1971 and moved with the franchise to Texas for the 1972 season.
